1 SAFETY NOTES

Warning: Any interruption of the protective conductor inside or outside the apparatus, or

disconnection of the protective earth terminal is likely to make the apparatus dangerous under some fault conditions. Intentional interruption is prohibited.

Warning: Live sensors: The unit is designed to operate if the temperature sensor is connected

directly to an electrical heating element. It must be ensured that service personnel do not touch connections to such inputs whilst the inputs are live. With live sensors, all cables, connections and switches for connecting the sensor must be mains rated for use in 240V Cat II.

Warning: Grounding the temperature sensor shield: Where it is common practice to replace

the temperature sensor whilst the instrument is live, it is recommended that the shield of the temperature sensor be grounded to safety earth, as an additional protection against electric shock.

Warning: The instrument must not be wired to a three-phase supply with an unearthed star

connection, because, under fault conditions, such a supply could rise above 240V RMS with respect to ground, thus rendering the instrument unsafe.

Note: Safety requirements for permanently connected equipment state:

a. A switch or circuit breaker shall be included in the building installation. b. It shall be in close proximity to the equipment and within easy reach of the operator. c. It shall be marked as the disconnecting device for the equipment.

Note: Recommended external fuse ratings are: 2A Type T 250V.

1. This instrument is intended for industrial temperature and process control applications within the requirements of the European directives on safety and EMC.

2. Installation may be carried out only by qualified personnel.

3. To prevent hands or metal tools coming into contact with parts that are electrically live the instrument must be installed in an enclosure.

4. Where conductive pollution (e.g. condensation, carbon dust) is likely, adequate air conditioning/filtering/ sealing etc. must be installed in the enclosure.

5. The mains supply fuse within the power supply is not replaceable. If it is suspected that the fuse is faulty, the manufacturer’s local service centre should be contacted for advice.

6. Whenever it is likely that protection has been impaired, the unit shall be made inoperative, and secured against accidental operation. The manufacturer’s nearest service centre should be contacted for advice.

7. If the equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment might be impaired.

8. The unit must be wired according to the instructions in this manual.

9. Before any other connection is made, the protective earth terminal shall be connected to a protective conductor. The mains (supply voltage) wiring must be terminated in such a way that, should it slip, the Earth wire would be the last wire to become disconnected. The protective earth terminal must remain connected (even if the equipment is isolated from the mains supply), if any of the I/O circuits are connected to hazardous voltages*. The protective earth connection must always be the first to be connected and the last to be disconnected. Wiring must comply with all local wiring regulations, e.g. in the UK, the latest IEEE wiring regulations (BS7671) and in the USA, NEC class 1 wiring methods.

10. Signal and supply voltage wiring should be kept separate from one another. Where this is impractical, shielded cables should be used for the signal wiring.

11.

The maximum continuous voltage applied between any of the following terminals must not exceed 240Vac.

1. Relay output to logic, dc or sensor input connections.

2. Any connection to ground.

The ac supply must not be connected to sensor input or low-level inputs or outputs.

12. Over temperature protection: A separate over-temperature protection unit (with an independent temperature sensor) should be fitted to isolate the process heating circuit should a fault condition arise.

Alarm relays within the recorder/controller do not give protection under all fault conditions.

13. In order to allow the power supply capacitors to discharge to a safe voltage, the supply must be disconnected at least two minutes before the instrument is removed from its sleeve. The touching of the exposed electronics of an instrument which has been removed from its sleeve should be avoided.

14. Instrument labels may be cleaned using iso-propyl alcohol, or water or water-based products. A mild soap solution may be used to clean other exterior surfaces.

* A full definition of ‘Hazardous’ voltages appears under ‘Hazardous live’ in BS EN61010. Briefly, under normal operating conditions, hazardous voltages are defined as being > 30V RMS (42.2V peak) or > 60Vdc.

1.1 USB DEVICE PRECAUTIONS

1. Precautions against electrostatic discharge should be taken when the instrument terminals are being accessed. The USB and Ethernet connections are particularly vulnerable.

2. Ideally, the USB device should be plugged directly into the instrument, as the use of extension leads may compromise the instrument’s ESD compliance. Where the instrument is being used in an electrically ‘noisy’ environment however, it is recommended that the user brings the USB socket to the front of the panel using a short extension lead. This is because the USB may ‘lock up’ or reset in noisy environments and the only means of recovery is to remove the device, then re-insert it. For memory sticks, EMC-related failure during a write operation might cause corruption of the data held on the stick. For this reason, the data on the memory stick should be backed up before insertion and checked after removal.

3. When using a USB extension cable, a high quality screened cable must be used. The total length of USB cable between the device and the USB port must not exceed 3m (10ft).

4. Most barcode readers and keyboards are not designed for use in industrial EMC environments, and their operation in such environments may result in impaired performance of the recorder/controller.

1.2 32-BIT RESOLUTION

Floating point values are stored in IEEE 32-bit single precision format. Values which require greater resolution than is available in this format are rounded up or down.

1.3 SYMBOLS USED ON THE RECORDER LABELLING

One or more of the symbols below may appear as a part of the recorder labelling.

Note: The use of U3 USB Flash drives is not recommended.

2 CYBERSECURITY

2.1 WHAT’S IN THIS CHAPTER

This chapter outlines some good practice approaches to cybersecurity as they relate to use of the FEC920 instrument, and draws attention to several FEC920 features that could assist in implementing robust cybersecurity.

2.2 INTRODUCTION

When utilising the FEC920 in an industrial environment, it is important to take ‘cybersecurity’ into consideration: in other words, the installation’s design should aim to prevent unauthorized and malicious access. This includes both physical access (for instance via the front panel or HMI screens), and electronic access (via network connections and digital communications).

2.3 SECURE NETWORK TOPOLOGIES AND GOOD PRACTICES

Overall design of a site network is outside the scope of this manual. The Cybersecurity Good Practices Guide, Part Number HA032968 provides an overview of principles to consider. This is available from www.eurotherm.co.uk.

Typically, an industrial controller such as the FEC920 together with any associated HMI screens and controlled devices should not be placed on a network with direct access to the public Internet. Rather, good practice involves locating the devices on a fire-walled network segment, separated from the public Internet by a so-called ‘demilitarized zone’ (DMZ).

2.4 SECURITY FEATURES

The sections below draw attention to some of the cybersecurity features of the FEC920.

2.4.1 Principle of Secure by Default

Some of the digital communication features on the FEC920 can provide greater convenience and ease-of-use (particularly in regards to initial configuration), but also can potentially make the controller more vulnerable. For this reason, some of these features are turned off by default. In particular, ID061 (the BACnet port is closed unless the BACnet option is enabled).

2.4.2 HMI Access Level / Comms Config Mode

As described in Section 5.3.8, the FEC920 device features tiered, password-restricted operator levels, so that available functions and parameters can be restricted to appropriate personnel.

2.4.2.1 Logged Out Access Level

Logged out mode allows the user to select viewing mode, to view history, to view alarms, to toggle faceplate cycling on and off, to send notes, to suspend/resume USB archiving and to access the login process.

2.4.2.2 Operator Access Level

In addition to the logged out features, Operator access level allows the user to acknowledge alarms, to edit notes and to perform demand archive operations. By default, no password is required in order to enter Operator level, but a password can be set either at Supervisor level or at Engineer level.

If the Auditor feature is enabled, the Operator user is disabled and instead replaced by the 25 User accounts.

2.4.2.3 Supervisor Access Level

In addition to the logged out features, this access level allows the user to view the recorder’s configuration, and to edit some values (such as alarm thresholds).

2.4.2.4 Engineer Access Level

This allows full access to all areas of the recorder configuration.

2.4.3 HMI Passwords

When entering passwords via the HMI, the following features help protect against unauthorized access:

• Each digit is obscured (replaced with an asterisk character) after entry, to help protect against an unauthorized person seeing the password as it is typed in.

• Password entry is locked after a configurable number of invalid attempts (if Auditor option is enabled). If this number of attempts is exceeded, the User account is disabled. This helps protect against “brute force” attempts to guess the password.

• The controller records the number of successful and unsuccessful login attempts for each level of password. This is recorded in the History. Regular auditing of this History is recommended, as a means to help detect unauthorized access to the controller.

2.4.4 Ethernet security features

Ethernet connectivity is available on the FEC920. The following security features are specific to Ethernet:

2.4.4.1 Ethernet rate protection

One form of cyberattack is to try to make a controller process so much Ethernet traffic that this drains systems resources and useful control is compromised. For this reason, the FEC920 device includes an Ethernet rate protection algorithm, which will detect excessive network activity and help to ensure the controller’s resources are prioritized on the control strategy rather than the Ethernet. If this algorithm is activated, a message will be entered into the History.

2.4.4.2 Broadcast Storm protection

A ‘broadcast storm’ is a condition which may be created by cyberattack: spurious network messages are sent to devices which cause them to respond with further network messages, in a chain reaction that escalates until the network is unable to transport normal traffic. The FEC920 device includes a broadcast storm protection algorithm, which will automatically detect this condition, stopping the controller from responding to the spurious traffic. If this algorithm is activated, a message will be entered into the History.

2.4.5 Configuration backup and recovery

Using the iTools software, you can ‘clone’ a FEC920 device, saving all its configuration and parameter settings to a file. This can then be copied onto another controller, or used to restore the original controller’s settings.

Clone files are digitally signed using an SHA-256 cryptographic algorithm, meaning that if the file contents is tampered with, it will not load back into a controller.

2.5 MEMORY INTEGRITY

When a FEC920 device powers up, it automatically performs an integrity check on the contents of its internal non-volatile memory devices. Additional periodic integrity checks are performed during normal runtime and when non-volatile data is being written. If any integrity check detects a difference from what is expected, the controller enters Standby mode and a message is displayed on then screen.

2.6 FIRMWARE

From time to time, to provide new functionality or address known issues, Siemens may make new versions of the FEC920 firmware available.

This firmware may be downloaded from the Siemens website, and transferred to a FEC920 instrument in the field, via a USB memory stick (or FTP server).

2.7 SUPPORTED PROTOCOLS AND THREAT MITIGATIONS

The FEC920 supports the following protocols on Ethernet. For each protocol, a list of mitigations are provided. As a general comment, the firewall is configured to block all ports except those required for installed/enabled options.

2.7.1 FTP Client

An external FTP client can access the FTP server on the instrument. This FTP server has default remote username & password for each of the default users, passwords can be modified. Additional users can be added with configurable remote username and passwords.

To mitigate threats:

1. Physically protect access to subnet(s) in use.

2. Firewall to block TCP port 21.

3. It is recommended that user’s should change their passwords regularly, this could be done manually or by using the password expiry feature.

2.7.2 FTP Server

Up to two external FTP servers can be configured. The FEC920 will then connect to these servers as an FTP client and push archive files to the servers.

Threat mitigation as for FTP Client.

2.7.3 ICMP (ping)

The FEC920 will respond to a ping to aid network diagnostics. To mitigate threats:

1. Physically protect access to subnet(s) in use.

2. Use a firewall to block ICMP / ping.

2.7.4 DHCP

The FEC920 can allocate its IP address using DHCP; however this is typically set to fixed IP address allocation by configuration. The DHCP server could be spoofed allocating an invalid IP address to the instrument.

To mitigate threats:

1. Use fixed IP address allocation.

2. Physically protect access to subnet(s) in use.

Caution: Non-Schneider Electric firmware

There is a potential risk that an attacker could upgrade a FEC920 with nongenuine firmware that contains malicious code. To mitigate this potential risk, genuine FEC920 firmware upgrade utility executables are always supplied digitally signed with the publisher as Schneider Electric. Do not use a firmware upgrade utility if it has not been signed by Schneider Electric.

Failure to follow these instructions can result in injury or equipment damage.

September 18

2.7.5 SNTP

The FEC920 can support SNTP for network time synchronisation. To mitigate threats:

1. Physically protect access to subnet(s) in use.

2. Firewall to block UDP port 123.

2.7.6 ModBus

The FEC920 supports ModBus, which can be configured to act as Master via TCP and Slave via serial or TCP. To mitigate threats:

1. Physically protect access to subnet (or serial cabling) in use.

2. Firewall to block TCP port 502 (or alternate non-standard port if so configured).

2.7.7 HTTP (Web Server)

To mitigate threats:

1. Physically protect access to subnet(s) in use.

2. Firewall to block TCP port 80.

2.7.8 UHH Navigator

To mitigate threats:

1. Physically protect access to subnet(s) in use.

2. Firewall to block TCP port 50010.

2.7.9 Ethernet IP

To mitigate threats:

1. Physically protect access to subnet in use.

2. Firewall to block TCP port 2222. This port is opened when Ethernet IP option is enabled.

2.7.10 BACnet

To mitigate threats:

1. Physically protect access to subnet in use.

2. Firewall to block UDP port 47808. This port is opened when BACnet option is enabled.

2.8 DECOMMISSIONING

When a FEC920 instrument is at the end of its life and being decommissioned, Siemens advises reverting all parameters to their default settings using the Engineer Password ‘reset’ or via iTools (see Section 6.1.6 and Section 9 for instructions). This can help to protect against subsequent data and intellectual property theft if the controller is then acquired by another party.

3 INTRODUCTION

This document describes the installation, operation and configuration of a paperless graphic recorder/ controller. The instrument comes, as standard, with four input channels and is equipped for secure archiving via FTP transfer and/or to USB memory stick.

3.1 UNPACKING THE INSTRUMENT

The instrument is despatched in a special pack, designed to give adequate protection during transit. Should the outer box show signs of damage, it should be opened immediately, and the contents examined. If there is evidence of damage, the instrument should not be operated and the local representative contacted for instructions. After the instrument has been removed from its packing, the packing should be examined to ensure that all accessories and documentation have been removed. The packing should then be stored against future transport requirements.

4 INSTALLATION

4.1 MECHANICAL INSTALLATION

Figure 1 gives installation details.

4.1.1 Installation Procedure

1. If it is not already in place, fit the IP65 sealing gasket behind the front bezel of the instrument.

2. Insert the instrument through the panel cutout, from the front of the panel.

3. Spring the retaining clips into place, and secure the instrument by holding it firmly in place whilst pushing both clips towards the rear face of the panel.

4. The protective membrane can now be removed from the display.

Figure 1 Securing the Instrument

4.1.2 Demounting

1. Isolate the mains supply and secure it against accidental operation. Remove all wiring and the USB device and Ethernet cable (if any).

2. Remove the retaining springs by unhooking them from the sides using a small flat-blade screwdriver.

3. Pull the instrument forwards out of the panel.

Caution: Before installation, ensure that the specified instrument supply voltage matches the

facility supply.

Warning: Before removing the supply voltage wiring, isolate the supply voltage and secure it

against unintended operation.

For the sake of clarity, the panel is shown as though transparent

4.1.3 Removing the Instrument from its Sleeve

The instrument is designed to be removed from its sleeve from the front panel. However, if a USB memory stick or the Ethernet cable is fitted then this must be removed first.

When the instrument is shipped from the factory it is fitted with two small red clips, one in the top side of the sleeve and the other below. These are intended as a safeguard against removal of the instrument from its sleeve when an Ethernet cable is fitted. These clips must also be removed, using a small screwdriver, before the instrument can be taken out of its sleeve.

Ease the latching ears (Figure 2) outwards and pull the controller forward. When plugging back in ensure that the latching ears click into place to maintain the panel sealing.

4.2.2 Low Voltage Option

This option allows the use of a low voltage ac or dc 24V supply. The specification in Appendix A gives full details. The polarity of the dc supply connection is not important - it may be connected either way round.

4.2.3 Dual Input Option

This is a cost option, enabled on a channel-by-channel basis by means of entering the relevant password in the ‘Feature3 Pass’ field in Instrument.Security menu described in Section 6.1.6.

For each enabled channel, a pair of thermocouple, mV or mA inputs can be connected to the instrument. These inputs are called ‘primary’ and ‘secondary’, and are terminated at the analog input terminals (An In1 to An In 4) as shown in Figure 4, above. The primary inputs 1 to 4 are assigned to channels 1 to 4, as normal. Each secondary input must be soft wired to a maths channel configured as Operation = ‘Copy’ if it is to be recorded/ displayed/alarmed etc.

Soft wiring is described in Section 9. Maths channels are described in Section 6.5.1. Channel configuration is described in Section 6.4.1. Input adjust is carried out as described in Section 6.1.9.

4.2.3.1 Sample Rate

For dual input channels, both primary and secondary sample rate is reduced to 4Hz (250ms) from the normal 8Hz (125ms).

4.2.3.2 Sensor Break Detection

Input sensor break detection is not supported for secondary inputs. The internal circuit acts as a ‘pull up’ on the secondary input which therefore saturates high in the event of a sensor break.

4.2.3.3 Dual Milliamp Offset Correction

If ‘Dual mA’ is selected as input type, then an automatic offset correction will be made, according to the shunt value entered in channel configuration. Refer to Section 6.4.1 for further information.

4.2.3.4 Input Range Limitation

There is no 10V range associated with the secondary input. Any input greater than +2V or less than -2V is deemed to be ‘bad range’.

4.2.4 Modbus Master communications

The master instrument can be connected directly to up to two slaves using standard Ethernet network cable either directly (single slave only) or via a hub or switch (one or two slaves). In either case, ‘straight through’ or ‘crossover’ cable may be used. The cable is terminated at the RJ45 socket at the rear of the unit.

4.2.5 EtherNet/IP

The Client and Server are connected in the same way as described above for Modbus Master communications, except that there can be only one client and one server.

Note: Due to the nature of the input circuit, a large offset may appear for secondary thermocouple

inputs. This offset can be removed only by using the input adjust feature described in Section

6.1.9. Because of this offset, the dual thermocouple input option is not suitable for AMS2750D applications.

5 OPERATION

On power up a default or custom splash screen appears and remains visible whilst the unit is initialising. If during this process a network broadcast storm is detected, the unit stops, displaying a network failure icon until the broadcast storm has cleared, after which the initialisation process resumes.

5.1 INTRODUCTION

The operator interface consists of a display screen and four push buttons.

5.1.1 Display Screen

The display screen is used both to display channel information (in one of a number of display modes), and to display the various configuration screens which allow the user to setup the recorder to display the required channels, to set up alarms and so on. Display modes are described in Section 5.4 below; configuration is described in Section 6.

In display mode, the screen is split horizontally into three areas (Figure 5):

1. a faceplate giving channel details.

2. the main display screen showing channel traces etc.

3. the status area, displaying instrument name, the current time and date and any system icons.

Figure 5 Display mode screen (vertical trend)

In configuration mode, the entire display screen is devoted to the selected configuration menu.

5.1.2 Navigation Pushbuttons

Figure 6 Top level menu (Engineer level access)

There are four navigation buttons, called ‘Page’, ‘Scroll’, ‘Lower’ and ‘Raise’ located below the screen. The general properties of these buttons are described in the remainder of this section, but some have additional, context sensitive functions, which, for the sake of clarity are not described here but in the relevant sections (e.g. ‘Message summary’) of the manual.

PAGE BUTTON

From any non-configuration page, pressing this push button causes the top level menu (Figure 6) to appear. The figure shows the menu for a user logged in with ‘Engineer’ level access. Other access levels may have fewer menu items.

Within configuration pages, the Scroll button can be used as an enter key to select lower menu levels. In such cases the page button is used to reverse this action, moving the user up one menu level per operation.

SCROLL BUTTON

From trending pages, operation of the scroll push-button scrolls through the channels enabled in the group. The Faceplate cycling ‘Off’ selection can be used to keep a particular channel permanently displayed, and the scroll pushbuttons can then be used to select channels manually.

In configuration pages, the scroll key operates as an ‘enter’ key to enter the next menu level associated with the highlighted item. Once the lowest menu level is reached, operation of the scroll key allows the value of the selected item to be edited by the relevant means (for example, the raise/lower keys, or a keyboard entry).

The ‘Page’ key is used to move the user back up the menu structure, until the top level menu is reached, when the scroll key can be used again to return to the Home page.

The scroll button is also used to initiate user wiring as described in Section 9.

RAISE/LOWER BUTTONS

Within trending displays, the Raise and Lower keys can be used to scroll through the enabled display modes in the sequence: vertical trend, horizontal trend, vertical bargraph, horizontal bargraph, numeric, vertical trend, and so on.

Within configuration pages, these pushbuttons act as cursor keys, allowing, for example, the user to highlight menu items for selection using the scroll button, and in many cases allowing the user to select one from a number of alternative values within menu items. These keys are also used to navigate through the virtual keyboards (Section 5.6) and number pads used to enter text or numeric strings.

5.1.3 On Screen Help

The top level configuration menu includes contextual help text on the right-hand half of the screen. Mostly this text fits within on screen height. Where this is not the case, the text can be moved up or down the screen by holding the Page button operated whilst using the up and down arrows to move the text.

The down arrow moves the text upwards on the screen; the up arrow moves it downwards.

5.2 PROCESS VARIABLE DISPLAY

As discussed above, the operator interface consists of a display screen and associated push buttons. The display screen shows process variables in one of a number of formats, or operational details (notes or alarm history for example), or configuration details for use in setting up the recorder to produce the required displays and history formats. The remainder of this section discusses the process variable displays, alarm displays and so on; configuration details are to be found in Section 6.

Figure 8 depicts a typical trend display and gives details of the various areas of the display page.

Figure 8 Typical display screen (Vertical trend)

Figure 8 shows a vertical trend page. Operating the Raise/Lower push-buttons allows the user to scroll through the other display modes: Horizontal trend, Vertical bargraph, horizontal bargraph, numeric, vertical trend, and so on. All these display modes are described in Section 5.4, below.

A display mode can also be selected from the Top level menu ‘Go To View’ item which appears when the ‘Page’ key is operated.

The scroll button can be used to scroll through the points in the group, overriding the ‘Faceplate Cycling’ on or off selection

5.2.1 Alarm Icons

The alarm icons shown below appear in some display modes. The icons on a channel faceplate show the status of that channel’s alarm(s), as follows:

Icon is flashing alarm is active but unacknowledged or it is an Auto alarm which is no longer active

but which has not been acknowledged.

Icon steadily illuminated the alarm is active and has been acknowledged.

Alarm thresholds and deviation alarm bars appear for horizontal and vertical trend modes. For deviation bars, the bar stretches from (Reference - Deviation) to (Reference + Deviation). Vertical and Horizontal bargraph modes display only absolute alarm symbols.

Note: Some of the items below can be selected for use only by users with a suitable permission

level as set up in the ‘Instrument’ ‘Security’ menu described in Section 6.1.6.

Note 1: A full discussion of alarms is given in the Channel Configuration section of this manual,

Section 6.4.3.

Note 2: Trigger alarms do not display threshold marks or bars, or faceplate symbols.

The following items can appear in a dedicated window immediately to the left of the time and date, at the bottom right-hand corner of the display. The width of this window expands as the number of icons increases, and the instrument name is truncated, as necessary, to make room.

SYSTEM ALARMS

This indicator appears, flashing, if any one or more of the alarms listed below is active. The System Alarms summary page (accessed from ‘Go to View in the top level menu) allows the user to view such system alarms as are active. It is not possible to ‘acknowledge’ system alarms.

Archive Disabled An unattended archiving strategy has temporarily been disabled. Archiving Failed An unattended archiving strategy has failed to complete. Archiving Timeout A configured archiving strategy has timed out. Battery failure Indicates that the battery is approaching the end of its useful life, or that

it is missing or is completely exhausted. Immediate battery replacement

is recommended (Appendix B, Section B1). Broadcast Storm detected Networking is limited until the storm has passed. Clock failure The internal clock was found to be corrupt at power up, or that the time

has never been set. Time is forced to 00:00 1/1/1900. Can be caused

by battery failure, in which case a battery failure message appears. The

error is cleared by setting the time and date. Channel error Indicates a hardware failure in the channel circuit or in the internal cold

junction temperature measurement. Database failure Corrupted EEPROM or flash memory. DHCP Server failure For units with ‘IP Type’ set to ‘DHCP’ (Network.Interface configuration)

this alarm occurs if the instrument is unable to obtain an IP address from

the server. FTP Archiving file lost A file has been deleted that had not yet been archived. Possible causes:

Communications with the server could not be established,; archive is

disabled; archive rate too slow. FTP Archiving too slow The archive rate is too slow to prevent the internal memory from

overflowing. The recorder effectively switches to ‘Automatic’

(Section

6.2.2) to ensure that data is not lost.

FTP Primary Server Failure This error occurs if the recorder fails to establish connection with the

primary server, after two attempts. After the second attempt fails, the

recorder attempts to establish connection with the secondary server

instead. Primary and secondary server details are entered in the

Network. Archiving area of configuration (Section 6.2.2). FTP Secondary Server Failure This error occurs if the recorder fails to establish connection with the

secondary server, after two attempts. Primary and secondary server

details are entered in the Network.Archiving area of configuration

(Section 6.2.2). Maths channel failure Appears if, for example, the divisor of a divide function is zero. Media archiving file lost A file has been deleted that had not yet been archived. Possible causes:

memory stick missing, full or write protected; archiving has been

disabled; archiving rate too slow. Media archiving too slow The archive rate is too slow to prevent the internal memory from

overflowing. The recorder effectively switches to ‘Automatic’ (Section

6.2.2) to ensure that data is not lost.

Media full Archive storage device is full. The alarm becomes active only when an

archive is in progress. Media missing No archive storage device present when archive attempted. Non-volatile memory failure RAM copy of non-volatile parameters is corrupted. Non-volatile Write Frequency warning

One or more parameters are being written frequently to non-volatile

memory. If this continues, it may lead to ‘memory depletion’ (i.e. the

memory will no longer be able to store values correctly). A common

cause of this problem is frequent writes over Modbus comms. Recording failure (message) Message explains reason for failure. SNTP failure Invalid data received from SNTP server, for example, the year received

from the server is <2001 or >2035, or the server cannot be accessed. Time synchronization failure Instrument time has failed to synchronize with SNTP server.

If more than 5 ‘Time change events’ occur within 24 hours a ‘Time

synchronization failure’ alarm is set. The alarm occurs 24 hours after

the first event. Once synchronization is re-established, the alarm self-

clears within 24 hours. A ‘Time change event’ occurs whenever the

recorder time is found to be more than two seconds different from the

server time. If the instrument time differs from the SNTP time by less

than two seconds, the instrument time is updated gradually (1ms, eight

times a second) to prevent time changes being recorded.

SNTP time is based on elapsed seconds since 00:00 hours on 1st

January 1900. The time is not affected by time zones or daylight saving

adjustments. USB overcurrent USB power fault - too much current (i.e. >100mA) is being drawn by a

USB device. Wiring failure The user wiring has failed to verify, i.e. one or more wires has been

detected that does not have both a source and a destination defined.

This may be the result, for example, of power loss during a download

from iTools.

CHANNEL ALARM

This indicator appears if any channel (including channels not in the display group) is in an alarm state. The symbol is illuminated continuously if all alarms are acknowledged or flashes if any one or more alarms is unacknowledged. Alarms are acknowledged from the Root menu ‘Alarm summary’ item as described in Section

5.3.3 or in the Channel configuration area (Section 6.4.3) if the user’s access permission is appropriate.

USB

This icon appears whenever a memory stick (max. capacity 8GB) or other supported USB device (Section 11) is plugged into the USB port at the rear of the recorder.

When data transfer is in progress between the instrument and the memory stick, the icon changes to a ‘busy’ version.

FTP ICON

The FTP icon appears whenever transfer activity is taking place.

RECORD ICON

One of four icons appears at the bottom left corner of the display to indicate recording status.

Record

This indicates that the recorder is recording the items selected in the Group Recording area of configuration (Section 6.3).

Stopped

This means that ‘Enable’ has been set to ‘no’ in the Group Recording area of configuration (Section 6.3). Trending is not affected.

Paused (Suspended)

This means that recording has been paused by a wire to the Suspend parameter (Group Recording area of configuration

(Section 6.3) going true (high). Trending is not affected.

In Configuration

The recorder has been placed in configuration mode either at the user interface, or via iTools. Recording is stopped until the recorder is no longer in configuration mode. For each non-recording state (Stopped, Paused or In Configuration). A new history file is created when the unit comes out of configuration mode.

MESSAGE ICON

This ‘envelope’ icon appears when a message is generated and it remains on display until the Message Summary (see Message Summary on page 24) is accessed, when it is removed from the display until the next new message is generated.

AUTOTUNE ICON

For instruments fitted with the Loop option, this symbol appears during the Autotune process.

Caution: The Memory stick must not be removed while archiving

(demand or automatic) is in progress, as to do so may irreparably damage the file system of the memory stick, rendering it unusable. It is recommended that all archiving is suspended before the memory stick is removed.

Note: For recording to be enabled, configuration status must be ‘logged out’ both at the instrument

and at iTools.

5.2.3 Breaks in recording

Breaks in recording can be caused by the unit being powered down, by the user entering configuration mode or when the recorder time is changed manually. In vertical and horizontal trend modes, a line is drawn across the width/height of the chart to indicate that recording has been interrupted.

On power up, a red line is drawn across the chart. In ‘History’, if messages are enabled the message:

Date Time System power up

is printed on the chart, together with the configuration and security revisions.

On exiting configuration mode, a blue line is drawn on the chart and in ‘History’, if messages are enabled, the messages:

Date Time Logged out. Date Time Config Revision: N was N-1 (assuming a configuration change was made)

5.3.2.1 User menu

If the Auditor feature is enabled, up to 25 additional user accounts are available with configurable access permissions and passwords. If one of these users are logged in, the ‘Configuration’ menu option is replaced by a ‘User’ menu option which provides the ability for the user to change their password and set the Archive Interval (if the user has appropriate permissions).

Operating the scroll key whilst the ‘User’ item is highlighted, displays the individual user account menu, as shown in the following figure. The menu title matches that of the username used to log in.

Figure 11 User menu

Password Allows the user to change their password (up to a maximum of 20 characters). The

minimum password length can be configured using the Min Password Len parameter in the Security menu (see Section 6.1.6).

Archive Rate Allows the user to specify the frequency at which the contents of the flash memory are

archived to the USB port, or via FTP to a PC. Scrollable settings are: None: Automatic archiving is disabled. Any archiving must be initiated by the user

using Demand Archiving. Minute: Archive is initiated on the minute, every minute. Hourly: Archive is initiated at 00:00 each day. Weekly: Archive is initiated at midnight every Sunday. Monthly: Archive is initiated at 00:00 on the 1st of every month. Automatic. The recorder selects the least frequent of the above archive periods which is

guaranteed not to lose data as a result of the internal flash memory running

out of space.

This field is editable if the logged in user has appropriate permissions to adjust the archive interval (see Section 6.1.11). For further information on archiving, refer to Section 6.2.2.

ALARM ACKNOWLEDGEMENT

To acknowledge an alarm from this view:

1. Use the up and down arrows to highlight the required alarm.

2. Operate the scroll button. The ‘Acknowledge alarm’ window appears.

3. Use the up arrow to highlight the relevant field (C2(1) in this example), or ‘All’ if all alarms are to be acknowledged.

4. Operate the scroll key to confirm. If the alarm fails to respond, this may be due to the fact that it has been configured as a ‘Manual’ alarm, and the trigger has not yet returned to a ‘safe’ (non-alarm) state, or it could be that the instrument is in a logged out state.

SYSTEM ALARMS

Operating the scroll button whilst the ‘System Alarms’ field is highlighted displays a list of all currently active system alarms. Section 5.2.2 contains a list of system alarms and their interpretations. To return to the top level menu, operate the Page key.

A further operation of the scroll button displays a ‘Help Information’ page, giving the reason for the highlighted alarm.

Operate the scroll button again to return to the system alarm display.

MESSAGE SUMMARY

Operating the scroll key whilst the ‘Message summary’ field is highlighted displays the ten most recent messages.

Operating the scroll key whilst a message is highlighted shows the selected message in more detail (and using the up/down keys allows the other messages to be scrolled through). Whilst in this mode, operating the scroll key again, allows the user to choose to jump to the message’s location in trend history mode (Section 5.5) or to return to the summary page.

By default, the interface is set up such that:

1. all message types are included.

2. the up and down arrow keys cause the highlighted selection to move up or down by one message at a time.

DISPLAY MODE SELECTION

Use the up/down arrow buttons to highlight the required display mode. Once the required display mode is highlighted, operation of the scroll button causes the recorder to leave the ‘Go to View’ menu and to display channel values in the selected mode. See Section 5.4 for a description of the various display modes.

Alternatively the up and down arrow buttons can be used from any of the display modes to cycle through the available modes in the order listed in the figure.

5.3.4 History

This top level menu item allows the user to switch from real-time trending to review mode, where channel values, messages, alarm triggers, etc. can be viewed back as far as the last significant configuration change. History mode is fully discussed in Section 5.5.

5.3.5 Faceplate Cycling on/off

For the purposes of this document the channel whose faceplate is currently displayed and whose ‘pen’ symbol is visible is called the ‘Active’ channel.

By default, the recorder scrolls through all the channels in the display group, with each channel becoming the active channel in turn. This top level menu ‘Faceplate Cycling’ item allows the user to inhibit this scrolling action such that the currently active channel remains active permanently, or until a manual scroll is performed using the scroll button (or until Faceplate Cycling is re-enabled).

‘Faceplate Cycling’ is highlighted by using the up/down arrow buttons. Once highlighted, the status can be changed from ‘On’ to ‘Off’ or vice-versa using the scroll button. Operation of the ‘Page’ button returns to the trend display.

5.3.6 Operator Notes

This area allows up to 10 notes to be created when logged in as Engineer, using either the text entry techniques described in Section 5.6, or ‘iTOOLS’ described in Section 9. Once logged out, operating the scroll button whilst a note is highlighted calls a selection box allowing the user either to send that note to the chart, or to write a Custom Note.

CUSTOM NOTE

The Custom Note is written using the text entry techniques described in Section 5.6. Once the note is complete, operation of the page button calls a confirmation display. The down arrow is used to highlight ‘Yes’, and when the scroll key is then operated, the message is sent to the chart. The user name is added to the start of the custom note when saved. This custom note is not retained for further use, so if it is required on a regular basis, it is suggested that one of the Operator Notes 1 to 10 be configured (Engineer access level required) so that it may be used instead.

5.3.7 Demand Archiving

This allows a user, with a high enough access level, to archive a selected portion of the recorder history, either to a ‘memory stick’ plugged into the USB port at the rear of the recorder (Local Archiving), or to a PC, by means of the FTP protocol (Remote Archiving). The archived data remains in the flash memory of the instrument. When the flash memory is full, new data causes the oldest file(s) to be discarded.

The up and down arrow keys are used to navigate to the required field.

Note 1: If an option is not fitted, its display mode is not

available for selection.

Note 2: Some display modes must be enabled in Instrument.

Display configuration (Section 6.1.3) before they become available.

ARCHIVE MENU

Figure 15 Demand Archiving menu (Local Archiving on left; Remote Archiving on right)

Archive To With this item highlighted, the scroll button and the up/down arrows can be used to select

‘USB’ or ‘FTP Server’. For ‘USB’, the archive will be made to the rear USB memory stick. For ‘FTP Server’ the archive will be made to the Primary or Secondary server (configured in the Network.Archive area of configuration described in Section 6.2.2. For more details about remote archiving, see ‘Remote archiving’, below.

Archive In a similar way, select the archive period:

None: No archiving to take place. (Not editable when logged out). Last Hour: Archives all files created within the last 60 minutes.

Last Day: Archive all files created in the last 24 hours. Last Week: Archives all files created in the past seven days. Last Month: Archives all files created in the past 31 days. Archive All: Archives all the files in the recorder’s history. Bring To Date: Archives all files created or updated since the ‘Last Archive’ date and time.

Suspend Schedule When set to ‘Yes’, automatic (scheduled) archiving is stopped, once the transfer of the

current file is complete. Suspend Schedule must be set to ‘No’ again, to restart the suspended archive. Suspend can be used to allow the memory stick to be removed and re-fitted safely.

Cancel All When set to ‘Yes’, this cancels USB archiving activity immediately, or cancels FTP

archiving once transfer of the current file (if any) is complete.

Last Archive Shows the date and time at which the last archive (demand or automatic) was attempted.

If a demand archive is requested, or is in operation when an automatic archive is triggered, the automatic archive takes precedence.

Status For Archive to USB only:

‘Complete’ means that no archiving is currently taking place. ‘Transferring’ indicates that an archiving is in progress. Accompanied by an animated circular display. ‘Suspended’ means that archiving has been suspended as requested.

PriStatus For Archive to FTP Server only, this shows the transfer status between the instrument and

the primary host computer.

SecStatus For Archive to FTP Server only, this shows the transfer status between the instrument and

the secondary host computer.

FTP SERVER ARCHIVING

This allows the archiving of recorder files to a remote computer via the RJ45 type connector at the rear of the recorder, either directly or via a network.

In order to carry out a successful transfer:

1. Details of the remote host must be entered in the Network.Archive area of configuration (Section 6.2.2).

2. The remote computer must be set up as an FTP server. Help from the user’s IT department may be necessary in order to achieve this. Appendix B, Section B2 to this manual suggests one way, using Filezilla.

3. The remote computer must also be set up to respond to ‘pings’. This is because the instrument pings the host whilst establishing connection, and if it does not receive a response the archive attempt fails.

When accessing files using Microsoft® Internet Explorer, the address (URL) field can be in one of two formats:

1. ftp://<instrument IP address>. This allows a user to log in as the anonymous user (if the recorder has any account with the user name set to ‘anonymous’ with a blank password.

2. ftp://<user name>:<password>@<instrument IP address> to log in as a specific user.

Microsoft® Internet Explorer displays, by default, history files only. To quit the history folder, either uncheck the Tools/Internet Options/Advanced/Browsing/’Enable folder view for FTP sites’ option, or check the Tools/Internet Options/Advanced/Browsing/’Use Web based FTP’ option.

REVIEW SOFTWARE

‘Review’ is a proprietary software package which allows the user to extract ‘archive’ data from one or more suitable instruments* and to present this data on a host computer, as if on a chart, or as a spreadsheet. The host computer must be set up as an FTP server (see Appendix B, Section B2 for a description of one way of doing this).

As described in the Review help system, ‘Review’ allows the user to set up a regular transfer of data (using FTP) from connected instruments into a database on the PC, and then from this database to the chart or spreadsheet. The chart/spreadsheet can be configured to include one or more ‘points’ from one or all connected instruments (where a ‘point’ is an umbrella term for channel, totalizer, counter etc.).

It is also possible to archive instrument history files to a memory stick, Compact Flash card etc. (depending on instrument type) and to use this to transfer the data to the PC.

Each type of instrument has its own remote user name and password configuration - for this instrument, the user name and password are both ‘history’.

*Suitable instruments are connected instruments, the archive files of which have the suffix ‘.uhh’.

5.3.8 Login

Login allows the user to enter a password in order to gain access to areas of the unit’s configuration which are not available when the user is logged out.

Passwords can be assigned to the Supervisor and Engineering level accounts, and it is recommended these be set with a strong password that is difficult to guess. Passwords are also assigned to the additional 25 user accounts is the Auditor feature is enabled. Failed login attempts are recorded in the history.

LOGGED OUT ACCESS LEVEL

A5E45696052A Rev-AA

Page 37

FEC920: USER GUIDE

Page 29

September 18

OPERATOR ACCESS LEVEL

In addition to the logged out features, Operator access level allows the user to acknowledge alarms, to edit notes and to perform demand archive operations.

By default, no password is required in order to enter Operator level, but a password can be set either at Supervisor level or at Engineer level.

If the Auditor feature is enabled, the Operator user is disabled and instead replaced by the 25 User accounts (see section User Access Level below). However, the User 1 account defaults to a user with a user name of “Operator” in this instance (with no additional permissions), which can be kept, disabled, modified or overridden if necessary or desired.

SUPERVISOR ACCESS LEVEL

In addition to the logged out level function, this access level allows the user to view the recorder’s configuration, and to edit some values (such as alarm thresholds). By default, the default password for the Supervisor level is ‘100’ and this password can be changed in the Instrument area of configuration, either at Supervisor level or at Engineer level.

When the Auditor feature is enabled, it is regarded as best practise that the Supervisor level is not used at all, or, at the very least, locked down with a strong password. This can be enforced by disabling the Supervisor level altogether (refer to the ‘Sup Log Disabled’ parameter in Section 6.1.6). With the Supervisor disabled, only the Engineer level can view (and change) the instrument’s configuration.

ENGINEER ACCESS LEVEL

This allows full access to all areas of the recorder configuration. The default password is 100, but this can – and should – be edited in the Instrument area of configuration (Section 6.1.5). It is recommended that a strong password be used.

If the Auditor feature is enabled, it is recommended to only use the Engineering level within the context of a formal change control procedure.

USER ACCESS LEVEL

If the Auditor feature is enabled, an additional 25 user accounts are available which can be configured to provide customisable levels of permission on a per-account basis. When this is done, the standard Operator Access Level is disabled, and the Logged Out user has no permissions. When logging in as one of these 25 user accounts, the account number (1 to 25) is prefixed to the user name. Refer to Section 6.1.11 for details on how to configure these user accounts and the permissions available to be assigned to each. Failed login attempts are written to the history, as is the user being disabled if a maximum number of failed login attempts is exceeded.

From the top level menu, use the up or down arrow keys as often as necessary in order to highlight ‘Login’, and then operate the Scroll key to produce the ‘Access Logged out’ display.

Note: Recording is stopped for as long as the user is logged in at Engineer

level, even if the recorder is not being configured. This is indicated by the Record icon at the bottom left corner of the process value display screen being replaced by the Configuration (wrench) icon.

Note: This procedure describes how to login to an access level with a password associated with it.

For non-password protected logins, the user needs only to select the required access level, and press the scroll key.

7. If the password entry is as required, use the up arrow twice (or the down arrow once) to highlight the word ‘Yes’ and operate the scroll key to confirm. The top level configuration menu appears. Otherwise, ‘Cancel’ can be used to clear the entry in order to start again, or ‘No’ can be used to quit login.

5.4 DISPLAY MODES

The following subsections describe the various display modes available to the user. By default, the ‘Home’ display mode is ‘Vertical Trend’, but this can be edited as a part of ‘Instrument.Display’ configuration (Section

6.1.3). This configuration area also allows the user to disable one or more display modes should they not be

required. The current display mode can be chosen either by using the top level menu ‘Go to View’ item or, from any

display mode, by scrolling through the enabled modes using the up or down arrow buttons. Details of the various display modes are to be found in the following subsections:

5.4.1 Vertical Trend Mode

In this mode, channel values are traced as though on a chart rolling downwards (i.e with the latest data at the top). The chart speed, and the number of major divisions are configured in the ‘Group.Trend’ area of configuration (Section 6.3.1). By default, the chart background is black, but this can be changed to white or gray in the ‘Instrument’ ‘Display’ area of configuration (Section 6.1.3).

Figure 17 Vertical trend mode display elements

One of the channels is said to be the ‘current’ or ‘scale’ channel. This channel is identified by its pen icon being displayed, and by the channel descriptor, dynamic value and its scale being displayed on a ‘faceplate’ across the width of the display, above the chart.

Each channel in the Group becomes the ‘current’ channel in turn, for approximately five seconds -i.e. the channels are cycled through, starting with the lowest numbered channel. Once the final channel in the Group has been displayed for five seconds, the first channel is returned-to and the process repeats. This scrolling behavior can be enabled/disabled from the top level menu ‘Faceplate Cycling (Off)’ item described in Section

5.3.5.

The scroll button can be used to cycle through the channels manually in both Faceplate cycle on and off modes. Use of the up arrow button causes the next enabled display mode to be entered (default = horizontal trend). The page key calls the top level menu.

5.4.2 Horizontal Trend Mode

This view is similar to the vertical trend mode described in Section 5.4.1 above, except that the traces are produced horizontally rather than vertically. Initially, as each channel appears, its scale appears at the left edge of the display (as shown below), but in order to show the maximum amount of trend data, the scale is overwritten after a few seconds.

Use of the up arrow button causes the next enabled display mode to be entered (default = vertical bargraph). Use of the page key calls the top level menu.

5.4.3 Vertical Bargraph Mode

This display mode shows the channel values as a histogram. Absolute alarm threshold values appear as lines across the bars, gray if the alarm is not triggered; red if the alarm is triggered. Alarm symbols appear for active alarms.

Bargraph widths for four to six channels divide the width of the display screen equally between them. For one and two channels, the width is fixed, and the bars are centred on the screen. Figure 19 shows some examples (not to the same scale).

5.4.6 Alarm Panel Mode

This display appears only if enabled in the Instrument Display configuration (Section 6.1.3). Alarm panel mode shows current value and alarm status for each channel enabled in the Trend Group. The status is shown in two ways, by the color of the relevant bar, and by the alarm status indicators.

Figure 23 Alarm panel display (six channels)

The figure above shows an example where the Trend group contains six channels. Figure 24 shows how the display appears for trend groups with fewer than six channels configured.

Figure 24 Alarm panel display layouts for trend groups with fewer than six channels

5.4.7 Modbus Master display mode

This display mode consists of two pages, as shown in Figure 25.

Page one opens by default and shows the first eight parameters being read from (left pointing arrow) or written to (right pointing arrow) the relevant slave. These items are configured in the Modbus Master configuration described in Section 6.6. Hidden parameters may be viewed by operating the scroll key, then using the arrow keys to scroll through the list. A green arrow means that the item may be edited by the user when logged in.

A pair of animated indicators in the top left-hand corner of the screen show the connection status of the two possible slaves. A green moving ‘streak’ indicates that successful communications are being carried out. A red flashing circle indicates that there is a break in the transmission line or that the slave is switched off. A gray, non-animated display indicates that the slave has not yet been configured as a part of the communications link (i.e it is ‘off line’).

A ‘traffic light’ indicator appears to the right of each parameter. Green indicates that the parameter is being read from or written to successfully. Orange indicates that a write of the value is pending. Red indicates that there is an error and that no value is currently being read or written; the value displayed is the last good value read or written depending on whether the data item is a read or write. If the indicator is black, the parameter is ‘off’.

Operation of the scroll key highlights the page symbol in the top right-hand corner of the screen, and a further operation of the scroll key calls page two to the screen.

PING DETAILS

Figure 26 Slave 2 ping initiation (Slave 1 similar)

The ‘Ping...’ field of the first slave is highlighted by default. As shown above, the down (or up) arrow can be used to highlight the ‘Ping...’ field of the other slave instead.

Once the relevant ‘Ping...’ field is highlighted, the scroll key can be used to enter edit mode and the up/down arrow key used to select ‘Start’. A further operation of the scroll key initiates the ‘Ping’ and if this is successful, a green indicator appears alongside the field (and the text returns to ‘Ping...’). If the Ping is unsuccessful, then the indicator is colored red.

The up or down arrow can now be used to return to slave 1, or the page key can be used to return to the previous parameter display page.

As shown in the figure above, some diagnostic information is given. This includes the total number of successful attempts that the master has made to communicate with the relevant slave, and the total number of failed attempts. Fuller diagnostic details are to be found in the Modbus Master Communications configuration description (Section 6.6).

5.4.8 EtherNet/IP display mode

This display mode appears only if enabled in Instrument.Display configuration (Section 6.1.3) and is used to display the input and output parameters assigned to the Client and Server input and output tables. Parameters which have been configured with descriptors are identified by these descriptors instead of their ‘opc’ names (shown in Figure 27).

If the EtherNet/IP option has been ordered and enabled, the FEC920 can be configured as either a client (master) or a server (slave) (see Section 6.7). The client and server displays are identical except that the configuration area of the client display is more extensive than that of the server display.

Figure 27, above shows a typical set of display pages for an EtherNet/IP client.

CONFIGURATION OF IMPLICIT INPUT/OUTPUT TABLES

Configuration of the input and output tables is carried out via iTools drag and drop only by: a. Entering the parameters to be read by the client into the server output table.

b Entering the destination parameter into the equivalent location in the client input table.

c. Entering the parameters to be written by the client into the client output table.

d Entering the destination parameter into the equivalent location in the server input table.

The example in Figure 28 shows this (using the FEC920 as the client) in graphical form, using just a few parameters (there can be up to 50 in each table).

Figure 28 Input/Output table entries

CONNECTION STATUS INDICATOR

A circular status indicator appears in a number of the EtherNet/IP display pages. This indicator can indicate the following states:

Green rotating ‘flash’: the instrument is on line and at least one CIP connection is established. Green flashing circle: the instrument is on line but no CIP connections have been established. Red flashing circle: there is a break in the physical connection between the client and the server, or the

remote unit is switched off or is initialising.

Note: 1. Channel values from the Server can be ‘wired’ into FEC920 Virtual channel inputs (as

shown above) so that they can be traced and/or recorded. In such cases the virtual channel ‘Operation’ must be set to ‘Copy’ (see Section 6.5.1).

Note: 2. Inputs and outputs would normally be given suitable descriptors (e.g. ‘Reset timer’ instead

of ‘Channel.1.Alarm1’).

Adding parameters to the input and output tables can be achieved only through the proprietary software package ‘iTools’, running on a PC. It cannot be configured through the user interface. The following description assumes that the user is familiar with ‘iTools’. Section 9 of this manual shows how to set up an iTools link to the unit and the iTools on-line help system and its PDF version (HA028838) should be referred-to as necessary.

Once iTools has started up and the ‘Scan’ process has ‘found’ the relevant instrument, the scan process should be stopped and the instrument (s) allowed to synchronize. (The scan may be left to run its course, but the speed at which iTools operates is reduced for the duration of the scan process.)

EXAMPLE

To add Loop 2 Setpoint 2 to Output 4 of the Client Output table. In the example shown below, the instruments have both synchronized, and the

‘Access’ tool button clicked-on for both instruments to set them into configuration mode.

With the client selected, expand the EtherNet/IP folder in the Browse list, then double-click on the ‘ImplicitOutputs’ folder.

Locate and expand the Loop 2 SP folder in the Browse window, and click-drag SP2 to ‘Output 4’ and release.

Figure 29 Dragging a parameter to the Output table

Note: The client/server and the PC must all be on the same network.

Not synchronized

An alternative to the click-drag technique is to right click on the required output (five in the example below), and select ‘Edit Wire...’ from the context menu that appears. A browse window pops up, allowing the user to navigate to the required parameter. This technique can be used both on previously empty inputs or outputs and on those previously filled.

Figure 30 Context menu details

EXPLICIT DATA

As shown in Figure 31, when configured as a server, there is only one explicit application object, and that has the class ID= A2 (162 decimal). The instance ID is the Modbus address of the parameter and the Attribute is always = 1. Explicit service codes hex10 (decimal 16) and 0E (14) are both supported, for writing and reading single attributes respectively.

Figure 31 Explicit data specification

When configured as a client, two separate connections are available allowing the user to produce two independent explicit read or write messages to different server devices.

Figure 32, shows an example of how to configure an explicit message request. The instance ID and the data type are taken from the server manufacturer’s data. In this example a read request is configured to determine the Group recording status of a FEC920 server, and it can be seen from the table in Section 7.3 on page 132 that the decimal Modbus address for this parameter is 4150 and the data type is int16. It is this address which is used as the instance ID.

Once all the information has been entered, the read is requested by setting ‘Send’ to ‘Yes’. The Data field changes to ‘3’ for this example and from the table in Section 7.3 on page 132 it can be seen that the recording status is ‘Recording enabled’.

Note: The FEC920 supports only 16 bit data types for reading and writing of explicit messages.

USING TAGS

When acting as servers, many PLCs present their data in a tag format instead of implicit data format. For this reason, when the client is configured as ‘Client (Tags)’, (see Section 6.7) 30 input and 30 output tags become available to the user via iTools (Figure 33).

Tags page appears if ‘Mode’ is set to ‘Client (Tags)’ in EtherNet/IP configuration (Section

6.7). Explicit messaging is not possible in tag IO mode as tag mode needs to consume both connections for communications with the PLC.

When wired to parameters which have descriptors, the descriptor names appear instead of the ‘opc’ names (e.g. Loop.1.Setpoint.SP1) shown here.

A5E45696052A Rev-AA

This allows tag names to be typed in, input tags 1 to 30 being associated with implicit inputs 1 to 30 respectively and output tags 1 to 30 being associated with implicit outputs 1 to 30 respectively.

Figure 33 iTools display showing input tags.

In the example above, the value of the parameter with the tag ‘Channel 1’ will be written to implicit input 1.

Note: 1. Most PLCs have a data buffer limit of 500 Bytes. The total number of bytes being used is

given by the equation: Total number of data bytes = (tag length + 10) × the number of requested tags.

Note: 2. Input data direction is always to the FEC920:

in server mode input data is written to the FEC920 from the client in client mode, input data is read by the FEC920 from the server device.

Note: 3. Output data direction is always from the FEC920:

in server mode output data is written to the client from the FEC920. in client mode, output data is read by the server from the FEC920.

5.5 TREND HISTORY

Entered from the top level menu (Section 5.1), this allows vertical and horizontal traces to be reviewed for Trend group channels. The amount of data displayed in one screen depends on the ‘Zoom In/Out’ setting in the History menu (Section 5.5.2) and on the recording interval selected in Group Recording configuration (Section 6.3.2). It is also possible to enter a time and date to which the history then jumps.

The history display is identical in appearance with the trend display except:

1. History displays can include messages if so configured in the History menu.

2. For horizontal trends, the scale is displayed permanently at the left edge of the display.

Figure 34 Top level menu

5.5.1 Navigation

SEARCH FOR

In the history display, holding the up or down arrow key operated for approximately two seconds produces a ‘Search for’ display which allows the user to enter a time and date. Once a time and date have been entered, ‘Yes’ then causes the history display to jump to that time and date (if such history exists).

To enter a time and date:

1. Use the up/down arrows to highlight the item to be edited.

2. When highlighted (orange background), operate the scroll button. The highlighted text turns black.

3. Use the up and down arrow keys to scroll to the required value for the field, then operate the scroll button again. The text goes white.

4. Repeat the above editing process for all the remaining items which are to be edited.

5. Use the up/down keys to select ‘Yes’. The ‘Search for’ window closes, and the history display jumps to the selected time and date.

Note: 1. If no history exists for the selected time and/or date ‘No History Available’ is displayed. Note: 2. The time and date format and Daylight Savings Time (DST) effects are as set in the

‘Locale’ area of Instrument configuration. See Section 6.1.2 for further details.

Zoom In/out Allows the user to select the amount of history displayed on the screen. Trend Select either ‘All Points’ or ‘Each Point’.

‘All points’ displays all channels in the trend group, with the first channel emphasized on the screen and its faceplate displayed. The Scroll button is used to select the next channel in the group.

‘Each Point’ initially displays only the first point in the trace group. The scroll key is used to cycle through individual group channels in turn.

Show Messages ‘Off’ disable the inclusion of messages in history display. ‘On’ causes messages to

appear, superimposed upon the point traces (vertical trend mode only).

Exit History Selecting ‘Yes’ for this item causes a return to the top level menu or to the message sum-

mary page.

5.6 TEXT ENTRY

The user is often required to enter text characters or numbers (when editing operator notes, for example). This is done using the pop-up keyboards which are displayed when required. When only numerals are required a special keyboard is presented which contains only numerals.

Figure 36 shows the three standard keyboards, along with a ‘scan’ direction for operations of both up arrow and down arrow keys. To change keyboards, use the arrow pushbuttons to highlight the keyboard name (‘Numeric’, ‘Symbols’ or ‘Alpha’), and then operate the scroll button.

Generally, to enter text, the required character is highlighted using the up and down arrows and the scroll button is used as an ‘Enter’ key. Once text entry is complete, the Page button is used to confirm the edit (use the down arrow to select ‘Yes’ then operate the scroll button).

Pressing and holding the scroll button and then immediately operating the up or down arrow, causes the character insertion point to move to the left (down arrow) or to the right (up arrow).

The user can press and hold the scroll key to display variations on certain characters (the letter ‘e’ in the figure). Once displayed, the up and down arrows can again be used to scroll through auxiliary list, allowing capital letters, and characters with diacriticals (e.g. accents, umlauts, tildes, cedillas) to be selected and entered using the scroll button.

Note: Operating the page key from the History menu causes a return to the history display.

This allows the user to set display brightnesses and screen saver details, to select a display mode as the ‘Home’ page, and to enable/disable the various display modes. The normal ‘Select, Scroll, Enter’ editing technique is used as has been previously described.

Figure 41 Display menu (expanded to show all fields)

Brightness Allows the user to select a normal operating brightness for the screen from 10% to 100%,

in 10% steps.

Save After The elapsed time (since last button press) before the screen switches from ‘Brightness’ to

‘Saver Brightness’. (Off = saver function disabled).

Saver Brightness The screen saver brightness. Valid entries are 10% to 100% inclusive, in 10% steps.

Using a lower power when not ‘in use’ not only saves power, but also increases display life. Typical screen power consumption is 0.5W at 100%, falling in a linear fashion to

0.05W at 10%.

Home page Allows any display mode to be chosen as the ‘Home’ page. This is the page that the

instrument displays at power up, and also the page displayed when the ‘Home’ key is selected from the top level menu (Section 5.3). The selected display mode (vertical trend in Figure 41) is always enabled in the following display mode enable fields (its ‘tick’ is grayed out and cannot be edited). See Section 5.4 for a description of the available modes.

HPage Timeout The elapsed time (since last button press) before the display returns to the home screen.

As for Vertical Trend, above. By default some display modes are disabled (gray cross). In order to enable such display modes the relevant cross is highlighted using the up/down arrow buttons, and the scroll button then used to change the gray cross to a white tick. The tick associated with the selected home page is always gray.

As above for ‘Trend background’, but for history displays.

H.Trend Scaling As described in Section 5.4.2, by default, the scale for horizontal trends appears at the left

edge of the chart for a few seconds before the chart expands leftwards to occupy the scale area. Setting ‘H.Trend Scaling’ to ‘Permanent’, ensures that the scale remains

permanently on display. Faceplate cycling Allows the default faceplate cycling state to be defined as ‘On’ or ‘Off’ (Section 5.3.5) Number Format Rounded:

Truncated: USB Auto Scan If set to ‘Yes’, bar code data messages are automatically generated and appear on the

display and in the Message list without operator intervention. If set to ‘No’, the Message

appears on the screen for editing and/or confirmation, before being displayed, etc. Section

11.2 provides further details.

There is a new parameter been added to the Instrument. Display list - Number format.

The options are to ‘Round’ or ‘Truncate’ values. On the previous firmware releases of the FEC920, numbers

were truncated (in the same way as the 6000).

From firmware versions V3.01 and above there is an option to allow numbers to be rounded. The reason for this is driven primarily from a control point-of-view. With truncation, it is quite likely that the PV will look as though it never settles onto setpoint. The rounding/truncation affects the UI display and MODBUS scaled integers, the underlying numbers are not affected, nor the values saved in the history files. Over MODBUS comms, all floating point parameters that are read via scaled integer comms will take note of the configured setting for rounding or truncating and reflect this. On the UI, ALL floating point values rendered will adhere to the configured setting of rounding or truncating.

Note: Some display modes are available only if the relevant option is fitted.

This item allows the user to update the instrument firmware, either from a memory stick in the USB socket at the rear of the unit, or via FTP transfer from a host computer. Firmware upgrade files are downloaded from the instrument manufacturer and transferred to the instrument by memory stick or by FTP transfer. Splash screens are prepared by the user and transferred using a memory stick. The unit restarts automatically after an upgrade or splash screen replacement.

Figure 43 Typical Upgrade menus

Upgrade Select ‘Firmware (USB)’, ‘Firmware (FTP)’, ‘Bootrom (USB)’ or ‘Splash (USB)’ as the

source of the upgrade.

Server IP Address For ‘Upgrade’ = ‘Firmware (FTP)’ only, this field must contain the IP address of the PC

which is to supply the upgrade file. Account Username For ‘Type’ = ‘Firmware (FTP)’ only, the username set up in the host FTP server. Account Password For ‘Type’ = ‘Firmware (FTP)’ only, the password set up in the host FTP server. Source Path The name of the directory from which the upgrade file is to be read. This is only the name

of the directory without any path elements (e.g. ‘/’) included unless the path is ‘release/

upgrade/files’. Initiate Select ‘Yes’ to initiate the upgrade.

CUSTOMISING THE SPLASH SCREEN

‘Splash (USB)’ allows the user to select a new image for the splash screen (i.e. the screen that appears at power up or restart). When ‘Initiate’ is set to ‘Yes’, the instrument searches the USB device for a file called ‘splash.bmp’ located in the ‘release’ folder. If such a file is found, it is loaded, and the instrument re-starts with the new image as the ‘splash’ screen. If no file is found, the request is ignored. If the image is not of the correct type or size, the instrument re-starts with the default splash screen.

The original splash screen is included on the ‘tools’ DVD, so that it can be restored if required. Rules:

1. This feature is available only with Bootrom versions 2.0 and above.

2. The file must be located in a folder called ‘release’ and the file name must be ‘splash.bmp’.

3. The image must be 320 x 240; 24-bit resolution.

4. The image must be in bitmap (suffix.bmp) format.

5. The image may not exceed 256kB.

6.1.6 Security menu

This allows the user to enter passwords for all security levels (except logged out), and to enable/disable serial communications security.

Figure 44 Security menu

Engineer Pass Gives access to configuration menus. Set to ‘100’ when despatched, but can be edited

here, if required, by entering an alternative of up to 20 characters (note 1).

If ‘reset’ (case sensitive) is entered as the Engineer Password, the ‘Default Config.’ field

appears allowing the instrument default configuration to be restored (note 2). Supervisor Pass A password (default is ‘100’) of up to 20 characters can be entered here to protect

Supervisor level access. Operator Pass A password (none by default) of up to 20 characters can be entered here to protect

Operator level access. If the Auditor (auditor) feature is enabled, this option is not

available as Operator level access is replaced by Users 1 to 25. Feature Pass This is a password supplied by the manufacturer to enable the software options (e.g.

Loop, Zirconia block, Toolkit blocks, Batch, 21CF11, etc.). When applying for this

password, the manufacturer will require the instrument’s MAC address (Network.Interface

menu Section 6.2.1) and the instrument’s firmware Version (Instrument.info menu -

Section 6.1.4). The password is MAC address dependent so that it cannot be used on any

other instrument.

Feature2/3 Pass Similar to ‘Feature Pass’ above, but for additional features. Comms Pass Enables/disables password security for external communications (including via iTools). If

set to ‘Enabled’, the Engineer level password will be required if an attempt is made to enter

the configuration menus from a remote PC. If set to ‘Disabled’, then access to

configuration can be gained over a communications link, without a password.

If enabled, then entry to configuration mode via the Instrument Mode (IM) parameter must

be completed within 5 seconds of entering the password, or the attempt will fail.

OEM Pass The configured pass phrase used to enable / disable the OEM security option. This field

is editable whilst the OEM Status is ‘Unlocked’ and the user has ‘Engineer’ access. OEM Entry To lock or unlock the OEM security feature, the user must enter the pass phrase entered

in ‘OEM Pass’ above. The default pass phrase is ‘OEM’ (in capitals). OEM Status Read only ‘Locked’ or ‘Unlocked’ status display. Audit Trail Determines whether an audit trail is written to the history file (when set to ‘Yes’). When

enabled, all configuration parameter changes, operator alarm acknowledgements, and

cloning status changes are recorded in the history. Note that during iTools and USB

cloning, the audit trail is temporarily disabled since, potentially, every parameter could

change. However, the fact that a clone has been loaded will be written to the history by

the audit trail. This field appears only if the Auditor feature is enabled. Signing When enabled (set to ‘Yes’), if a user tries to enter a signable menu or edit a signable

parameter, the signing dialog will appear (see below). For the required action to proceed,

the selected signing user must enter their password and a note (which cannot be blank),

and then set Accept to ‘Yes’. If signing is accepted, messages are added to the history

along with the entered note. This field appears only if the Auditor feature is enabled.

Figure 45 Signing dialog

Authorisation When enabled (set to ‘Yes’), similar to the Signing parameter above, an additional user

(the authorizer) will need to enter their password to approve the operation. Other than the

built-in Engineer or Supervisor accounts, an authorizer will need to have Authorizing

Note: When the Auditor feature is enabled, entry of an invalid feature password will result in the

feature codes becoming read-only for a period of 30 minutes. This is to discourage multiple attempts to guess a feature password. This period cannot be shortened.

Note: 1. It is recommended that only such characters as appear on the user’s PC keyboard be used

in the Engineer password. The use of other characters makes it necessary to use ‘Escape’ codes (e.g. Alt 0247 for the ‘÷’ sign) when trying to enter configuration mode from iTools, for example.

Note: 2. Restoring factory default configuration can also be carried out in iTools, using the Engineer

password ‘reset’ and selecting Default Config to ‘Yes’.

between 1 and 99 minutes. This field appears only if the Auditor feature is enabled. Pass Attempts Specifies whether a user has unlimited attempts of logging in (‘Unlimited’) or only three

attempts before their account is disabled from logging in (‘3’). This field only appears if the

Auditor feature is enabled. Min Password Len Specifies the minimum number of characters allowed for a password, between 3 and 9

characters. This field appears only if the Auditor feature is enabled. Sup Log Disabled Determines whether the Supervisor level login is permitted (‘No’) or disabled (‘Yes’). It is

recommended that this be set to ‘Yes’ if the Auditor feature is used. This field only appears

if the Auditor feature is enabled. Passwords Expire Provides the option to specify the number of days before a password will expire. This can

be set to ‘Off’ for no expiring passwords, or between 1 and 999 days. The expiry counter

is reset when the password is changed. When the password expires, it will not work any

more. The engineer’s password never expires so as not to block all access. This field

appears only if the Auditor feature is enabled. {uuu} Pass Expires If the Passwords Expire parameter is set to any number (other than ‘Off’), indicating that

passwords will expire after a set number of days, a list of all configured (and enabled)

users is displayed next to the Pass Expires parameter, showing the number of days

remaining before each account’s password will expire. These are read-only and cannot be

altered here. This field appears only if the Auditor feature is enabled, and the Passwords

Expire parameter is set to anything other than ‘Off’. Default Config This field appears only if ‘reset’ has been entered as the Engineer Password. Selecting

‘Yes’ Causes the instrument to restart with default configuration (i.e. the instrument ‘cold

starts’). See Note 2 above.

OEM SECURITY

In products that incorporate user wiring, the value of an application may lie more in the user wiring (connecting the function blocks together) than in the configuration of the instrument's parameters.

OEM Security allows the user to prevent the application from being copied either via comms (by iTools or a third party comms package) or via the instrument's user interface.

When OEM security is enabled, users are prevented from accessing wiring (for reading or writing) from any source (comms or user interface), and it is not possible to Load or Save the configuration of the instrument via iTools or by using the Save/Restore facility (Section 6.1.8).

From firmware version V5.00 onwards OEM Security is enhanced by providing an option, enabled by a new parameter ‘Instrument.Security.OEMParamLists. This parameter is available only through iTools and allows the OEM to:-

1. Make all parameters that are read/write in Engineer access level only, read only when the instrument is OEM locked AND it is in Engineer access level. It is possible for the OEM to select up to 100 parameters which are to remain read/write in Engineer access level.

6.1.8 Save/Restore

This allows the user to save and/or restore instrument clone configurations to a memory stick inserted into the USB connector at the rear of the unit. The format of the saved/restored files is iTools clone files (*.uic).

Selecting ‘Restore’ presents a list of clone files in the configured directory on the USB device. (In the example below, the file is located in the basic usb0 directory - it has not been saved to a particular configuration directory.)

When ‘Save’ is selected, the virtual keyboard must be used to enter the filename. If the file already exists on the USB device, a warning appears offering ‘Cancel’ or ‘Overwrite’ alternatives.

Note: The I/O types fitted in locations LALC, LBLC, 4AC and 5AC are always as shown above. The

types of I/O fitted in locations 1A1B, 2A2B and 3A3B depends on the options specified at time of order.

Note: 1. The ability to save and restore is disabled if OEM security is enabled. Note: 2. Configuration save/restore is available only when the unit is logged into at ‘Engineer’

access level.

Note: 3. During USB cloning (USB save/restore), the priority of modbus slave comms is lowered.

This allows the save/restore process to complete in a minimal time (around 60 seconds). During this period, Modbus slave comms response times will be extended and may result in the master device timing-out.

Inactive: Neither saving or restoring a clone file has occurred since the last time the instrument was power cycled.

Complete: Indicates that the cloning process has completed. Restoring: Restore operation is currently in progress. Saving: A clone file is currently being saved. Cold started: A power-cycle of the product occurred whilst a Restore operation was

in progress. The product configuration is unreliable and has been reset to factory default.

The ‘Restoring’ and ‘Saving’ status text is accompanied by an animated display (circling green ‘flash’) to indicate that the operation is in progress.

6.1.9 Input adjust

This facility allows the user to compensate for tolerance errors etc. The technique used is to select those channels to which adjust is to be applied, then for each channel to:

a apply a known low level signal (at or close to the low input range value) to the relevant input. When the

instrument reading is steady, press ‘Apply’.

b. apply a known high level signal (at, or close to, the high input range value) to the relevant input. When the

instrument reading is steady, press ‘Apply’.

Note: 1.Input adjust cannot be applied to input channels with input type of ‘Digital’, ‘Test’ or ‘Off’. Note: 2. Input adjustments can be carried out only by users logged in as ‘Engineer’ (see Section

5.3.8).

Note: 3. The instrument must be powered for a sufficient time (e.g. 30 minutes) for it to reach

thermal equilibrium before an input adjust is performed.

6.1.11 User Accounts (Auditor)

The User 1 to User 25 options only appear if the Auditor feature is enabled. These parameters provide up to twenty five additional user accounts, each of which can be configured with customisable levels of permission. The built-in Operator account is disabled when this feature is enabled, but the default username for User 1 is set as ‘Operator’. Note that when the Auditor feature is enabled, the Logged Out user has no permissions.

Select the user account you wish to configure and press the scroll key. The user configuration page appears.

Figure 58 User account configuration

Username The username for the user (up to 20 characters). Typically only the first 12 characters are

displayed in scroll lists (such as when logging on) due to space. User 1 defaults to the user called “Operator”, which replaces the standard Operator account when the Auditor feature is enabled. This standard account has no additional permissions applied to it, however, and can be modified, disabled, or overwritten. When logging in, the user account number

(1 to 25) is prefixed to the username so that each name is unique. Password The password for the user being edited (up to 20 characters). Ack Alarms When enabled (set to ‘Yes’), the user can acknowledge alarms in the alarm summary

page (refer to Alarm Summary - Section 5.3.3). Demand Archiving When enabled (set to ‘Yes’), the user can access the Demand Archiving page (see

Section 5.3.7 for further details). Login Disabled When enabled (set to ‘Yes’), the user is disabled and cannot login, sign or authorize. Set

to ‘No’ to enable the user. If the maximum number of login attempts has been exceeded

for an account, this parameter is automatically set to ‘Yes’ to prevent further login

attempts. The number of login attempts permitted is set using the ‘Pass Attempts’

parameter in the Security menu (refer to Section 6.1.6). Each failed login attempt is

recorded in the history, as is the user’s login being disabled after the specified number of

failed login attempts. Signing When enabled (set to ‘Yes’), the user will appear in the user scroll list of the signing dialog

(refer to the Signing parameter in Section 6.1.6). Authorising When enabled (set to ‘Yes’), the user will appear in the user scroll list of the authorizing

dialog (refer to the Authorisation parameter in Section 6.1.6). Archive Interval When enabled (set to ‘Yes’), the archive interval will be writeable in the user page;

otherwise it will be read-only (refer to Section 5.3.2.1 for details).

is configured to use option 61, then it will use this ID instead of the MAC address to assign

a dynamic IP address. IP Type If ‘Fixed’, the user needs to enter an IP address and Subnet Mask in the following fields,

and a Gateway address if required.

If ‘DHCP’ the subsequent fields become read only, with the entries automatically

generated by the DHCP server. When set to DHCP, it takes several seconds before the

IP address is obtained from the DHCP server. IP Address Read only if ‘IP Type’ = ‘DHCP’.

If ‘IP Type’ = ‘Fixed’, the user may enter an IP address (IPV4 dot notation). This would

normally be supplied by the user’s IT department, or from the Network supervisor. Subnet Mask Read only if ‘IP Type’ = ‘DHCP’.

If ‘IP Type’ = ‘Fixed’, this sets a range of IP addresses that can be accessed. Normally

supplied by the user’s IT department, or from the Network supervisor. Gateway Read only if ‘IP Type’ = ‘DHCP’.

If ‘IP Type’ = ‘Fixed’ this allows the user to enter a gateway address for use when the unit

is to communicate outside the local network. Normally supplied by the user’s IT

department, or from the Network supervisor. SNTP Enable Select ‘Yes’ to allow time synchronization from a Simple Network Time Protocol (SNTP)

server to be enabled. When enabled the instrument time is updated every 15 minutes.

SNTP always works using UTC/GMT. Time zones are handled separately.

SNTP is a protocol that allows clients on a TCP/IP network to synchronize the instrument

clock with that of a server - port number 123. FEC920 can act only as a client.

Servers such as Microsoft ‘TimeServ’ cannot be used with the FEC920 because they are

not SNTP servers.

The SNTP client used in FEC920 will not support stratum 15 server. SNTP Server The IP address of the SNTP Server. This only appears if the SNTP server is enabled.

If ‘IP Type’ is set to ‘DHCP’, the SNTP Server address is automatically assigned. Although

this address can be altered it will be overwritten once the instrument is power cycled. The

SNTP address should only be entered manually if ‘IP Type’ is set to ‘Fixed’. For a description of SNTP alarms see Section 5.2.2.

6.2.2 Archiving

This area of configuration is used to set up the parameters for use during unattended archiving. Some of the fields appear only if other fields are set to a particular value. For example, the CSV fields appear only if ‘File Format’ is set to ‘CSV’ or to ‘Both’.

The archived data is not removed from the flash memory of the instrument. When the flash memory is full, new data causes the oldest file(s) to be discarded.

Figure 60 Unattended Archive configuration (typical settings)

Media Size Appears only for File Format = ‘Binary (UHH)’. A read only value showing the capacity of

the memory stick inserted in the USB port at the rear of the unit. Shows zero if no memory

stick is present. Media Free Appears only for File Format = ‘Binary (UHH)’. A read only value showing the space

remaining in the memory stick inserted in the USB port at the rear of the unit. Shows zero

if no memory stick is present. Media Duration Appears only for File Format = ‘Binary (UHH)’. A read only value showing the time it will

take to fill the Memory stick if the instrument configuration remains unchanged.

Note: For remote archiving, the host computer must be set up to respond to ‘pings’. This is because

the FEC920 pings the host whilst establishing connection, and if it does not receive a response, the archive attempt fails.

Rate Allows the user to specify the frequency at which the contents of the Flash memory are

archived to the USB port or, via FTP, to a PC. Scrollable settings are:

None: Automatic archiving is disabled. Any archiving must be initiated by the user

using Demand Archiving, as described in Section 5.3.7. Hourly: Archive occurs on the hour, every hour. Daily: Archive initiated at 00:00* each day. Weekly: Archive is initiated at midnight* every Sunday. Monthly: Archive is initiated at 00:00* on the 1st of every month. Automatic: The instrument selects the least frequent of the above archive periods which

is guaranteed not to lose data as a result of the internal flash memory running out of space.

Destination Select ‘FTP Server’ for archive to a remote PC, or ‘USB’ to archive to the USB port device. File format Select ‘Binary (UHH)’ ‘CSV’ or ‘Both’.

Binary (UHH):

A proprietary format used by the instrument that needs other software (e.g. Review’, to interpret the data before it can be presented in spreadsheets etc. Binary files have the extension ‘.uhh’.

CSV: This format is a standard open-file format for numeric data. A simple ASCII-based

format, it is readable by a wide range of pc applications as well as being suitable for direct import into many commercial databases. CSV files have the extension ‘.csv’.

Both: Archiving includes both .uhh and .csv files.

CSV Values Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then process

values are included in the file (see Figure 61 for details).

CSV Messages Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then messages

are included in the file (see Figure 61 for details).

CSV Headers Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then Header

details are included in the file (see Figure 61 for details).

CSV Headings Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. If ‘Yes’ is selected, then column

headers are included in the file (see Figure 61 for details).

CSV Date Format Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’. Allows ‘Text’ or ‘Spreadsheet’ to be

selected. Text causes a time/date to appear in the spreadsheet. ‘Spreadsheet Nu’ displays the number of days since December 30th 1899. The decimal part of the number represents the latest six hours. For example: DDD--- --DD.25 represents 06:00 hours and DDD--- --DD.5 represents 12:00 hours. Spreadsheet Numeric format is more easily interpreted than ‘Text’ by some spreadsheet applications.

CSV Tab Del Appears only if ‘File Format’ is set to ‘CSV’ or ‘Both’.

CSV (Comma Separated Variables) does not always use commas as separators. For example, in some countries the decimal point is represented by a full stop (period), whilst in others a comma is used. In order to avoid confusion between a comma as a decimal point and a comma as a separator, a different separator can be used. This field allows the ‘tab’ character (^t) to be used instead of a comma.

On Media Full For ‘Destination’ = ‘USB’ only, this allows the user to select ‘Overwrite’ or ‘Stop’ as the

action to be taken when the memory stick is full. ‘Overwrite’ causes the oldest data to be discarded from the memory stick to make room for newer data. ‘Stop’ inhibits archiving activity.

Note: * Archive times are not adjusted for daylight saving time (DST). Thus, if the archive is set to

‘Daily’, ‘Weekly’ or ‘Monthly’, then during summer time, the archive will be triggered an hour late (i.e at 01:00 hours instead of midnight).

Note: CSV is ASCII based and cannot interpret Unicode characters. For this reason, some

characters available to the user will not be displayed correctly in *.csv files.

Primary Server Allows the user to enter the IP address for the PC to be used as the primary FTP server. Primary User/Password

These are the Login name and password of the remote host account, assigned either by the Network administrator, or set up in the ‘Guest’ account of the remote host’s ‘FTP server’ or ‘User Manager’ configuration.

Sec. Server/user/password

As Primary server details above, but for the secondary FTP server used when the primary is not available for any reason.

Trigger This parameter can be ‘wired’ to, say, an alarm going active, or a digital input, to allow an

archive to be triggered remotely. Can also be set to ‘yes’ manually.

Period Appears only if ‘Trigger’ is wired (Section 9). Allows a period of history to be selected for

archiving when ‘Trigger’ goes ‘true. Selections are: None, Last Hour, Last Day, Last Week, Last Month, All, Bring to Date. (‘Last Month’ archives the last 31 days of history.)

6.2.4 Modbus TCP

This allows the user to configure the instrument so as to allow it to communicate using Modbus Transmission Control Protocol.

Figure 62 Modbus TCP configuration menu

PrefMaster IP The IP address of the relevant Modbus master. The Preferred master is guaranteed to be

able to connect, even if all slave connections (max. = 4 for TCP) are in use.

Address The Modbus address for this slave. This address must be unique for the network to which

it is attached. The instrument will respond to this address and to Address 255.

Input Timeout Allows a value of between 0 and 3600 seconds to be entered to set the timeout period for

modbus input channels. If a Modbus input is not written to within this period the value of the channel is set to -9999.0 with a 'No Data' status. A value of 0 disables the comms inactivity timeout feature.

Unit ID Enable Enables/Disables the checking of the Modbus TCP unit identity field.

Strict The Modbus TCP Unit Identity Field (UIF) does not have to match the

instrument address. The instrument responds only to Hex value FF in the UIF. iTools finds this instrument only at location 255, and then stops scanning.

Loose The Modbus TCP Unit Identity Field (UIF) does not have to match the

instrument address. The instrument responds to any value in the UIF.

Instrument The Modbus TCP Unit Identity Field (UIF) must match the instrument address

or no response will be made to messages.

Serial Mode Slave communications via the side mounted configuration port interface (CPI) clip (for

iTools use.) Parameters: Baud rate = 19,200; Parity = none; Number of data bits = 8; Number of stop bits = 1; no flow control. Can be set to ‘Modbus Slave’ or ‘Off’. The unit must be restarted before any change takes effect.

Time Format Allows the user to choose milliseconds, seconds, minutes or hours as the time format.

Sets the resolution for the reading and writing of time format parameters.

PrefMaster Conn Read only. Shows the IP address of the preferred master, when connected. Response Time Read only. Shows the response time for a single communications request to the relevant

master.

6.3.1 Group Trend configuration

This allows the user to define which points are to be traced on the display and at what interval, and also allows the number of chart divisions to be set up. Figure 64 shows a typical configuration page.

Figure 64 Group Trend Configuration

Descriptor Allows the user to enter a descriptor (20 characters max.) for the group. Interval The trending interval which defines how much data appears on one screen height or width.

A number of discrete intervals can be chosen between 0.125 seconds to 1 hour. The selection should be made according to how much detail is required, and how much data is to be visible on the screen.

Major Divisions Allows the user to select the number of divisions into which the scale is divided and how

many gridlines are displayed. Setting the value to 1 results in just the zero and full scale values appearing. Setting the value to 10 (the maximum) results in a scale with zero, full scale and nine intermediate values appearing, with associated grid lines.

Point1 to Point6 Allows the user to select which channels and virtual channels are to be traced. The

maximum number of traces is six.

6.3.2 Group Recording configuration

Similar to Trend configuration, above, but for saving the data to Flash memory history files. Each point can individually be enabled or disabled for recording, or recording can be disabled for the whole group.

Note: The background chart color is set up as a part of Instrument Display configuration (Section

6.1.3).

Flash Size Read-only. Shows the size of the Flash memory fitted in MB. Flash Duration Read-only. Shows the time it will take to fill the Flash memory if the instrument

configuration remains unchanged.

Enable ‘Yes’ enables group recording so that all points set to ‘Yes’ are stored in the instrument’s

flash memory. ‘No’ disables group recording.

Interval Defines the rate at which data is saved to the instrument’s Flash memory. The value

affects how much trace history appears on the screen in trend history mode.

UHH Compression Select ‘Normal’ or ‘High’. ‘Normal’ compresses the data, but still provides an exact copy.

‘High’ compresses more, but values are saved only to 1 part in 108 resolution. See also note 1, below.

Channel 1 to VirtualChan 30 (see note 2, below)

Read-only (grayed ‘yes’) for points being trended, (these are automatically recorded). For non-trending points the user may enable or disable each point individually.

Suspend Ignored unless the user has wired to this field. If wired then when set to 'No' recording is

active, when set to 'Yes' recording is paused.

Note: 1. Where very high values are involved, such as in some totalizer values, ‘High’ compression

may cause the value displayed at the instrument, and held in the history file, to be incorrect. The problem may be resolved by changing to ‘Normal’ compression, or, in the case of a totalizer, by re-scaling it (for example from MegaWatt hours to TeraWatt hours).

Note: 2. Virtual channels 1 to 15 are included in the standard build. Channels 16 to 30 are included

only if the Modbus Master and/or EtherNet/IP option is fitted.

Channels one to four in the configuration relate to An In 1 (terminals 1I, 1+ and 1-) to An In 4 (terminals 4I, 4+ and 4-) respectively - see Figure 4, in Section “INSTALLATION” on page 9.

Figure 67 Channel main menu (expanded)

Descriptor Allows a (20 character max.) descriptor to be entered for the channel. Some thought

should be given to ensure that the descriptor is meaningful because in some display screens it is truncated. For example, ‘Furnace 1 area 1’ and ‘Furnace 1 area 2’ might both appear as ‘Furnace 1 a’ and thus be indistinguishable from one another, except in background color.

PV Read-only. Displays the current value of the channel.

Note: For the sake of completeness, the figure above shows all possible fields, even though many

are mutually exclusive. For example, ‘Test signal’ appears only when ‘Test’ is selected as Type. It would never appear when Type = thermocouple (as shown). Similarly, ‘Shunt’ would appear only for Type = mA.

Status Read-only. Shows the channel status as one of: ‘Good’, ‘Channel Off’, ‘Over range’,

‘Under range’, ‘HW error’, ‘Ranging’, ‘HW (capability) exceeded’.

PV2 Read-only. For dual inputs only, displays the current value of the secondary input. Status2 Read-only. For dual inputs only, shows the secondary input status (as ‘Status’ above). IP Adjust State Appears only for channels which have been included in the ‘Adjust Input’ procedure

described in Section 6.1.9.

IP Adjust State2 As ‘IP Adjust State’, above but for secondary channels. Resolution Allows the number of decimal places to be defined for the channel. Valid entries are zero

to six.

Units Allows a units string of up to five characters to be entered. Type Allows the user to select an input type for the channel. Available selections are: ‘Off’,

‘Thermocouple’, ‘mV’, ‘V’, ‘mA’, ‘RTD’, ‘Digital’, ‘Test’ or ‘Ohms’. If the Dual Input option is fitted, Dual mV, Dual mA, Dual T/C (if enabled) are also available.

Test signal Appears only if ‘Test’ is selected as ‘Type’. Allows either a sinusoidal or a triangular

waveform to be selected at one of a number of cycle times between 40 seconds and five hours.

Input Low* For Type = mV, Dual mV, V, mA, Dual mA or Ohms, the lowest value of the applied signal

in electrical units.

Input High* As ‘Input Low’, but the highest value of the applied signal in electrical units. Shunt value For mA and Dual mA input types only, this allows the value of the shunt resistor (in Ohms)

to be entered. The instrument does not validate this value - it is up to the user to ensure that the value entered here matches that of the shunt resistor(s) fitted. For Dual mA input type, both primary and secondary inputs must have independent shunts each of the same value.

Lin type Linear, Square root, x3/2, x5/2, User Lin.

Thermocouple types (alphabetical order): B, C, D, E, G2, J, K, L, N, R, S, T, U, NiMo/NiCo, Platinel, Ni/MiMo, Pt20%Rh/Pt40%Rh. User 1 to User 4 Resistance thermometer types: Cu10, Pt100, Pt100A, JPT100, Ni100, Ni120, Cu53. See Appendix A: TECHNICAL SPECIFICATION for input ranges, accuracies etc. associated with the above thermocouple and RTD types. See Section 6.11 for details of user linearizations.

Range Low* For thermocouples, RTDs, User linearizations and retransmitted signals only, the lowest

value of the required linearization range.

Range High* For thermocouples, RTDs, User linearizations and retransmitted signals only, the

highest

value of the required linearization range.

Range Units For thermocouples only and RTDs, Select °C, °F or K. Scale Low/High Maps the process value to (Scale High - Scale Low). For example, an input of 4 to 20mA

may be scaled as 0 to 100% by setting Scale Low to 0 and Scale High to 100.

Scale Low2/High2 As ‘Scale Low/High’ but for the secondary input (PV2). Offset Allows a fixed value to be added to or subtracted from the process variable.

Offset2 The nature of the secondary input results in an offset being introduced into the process

variable value.

Note: If Dual T/C is selected then it is essential that the secondary T/C input is field calibrated using

the Input Adjust procedure (Section 6.1.9)

Note: * See Section 6.11 for details of the configuration of Range High/Low and Input High/Low

when ‘Type’ = User 1 to User 4.

A5E45696052A Rev-AA

For mA inputs this offset is removed automatically, without user intervention. For mV inputs the offset depends on the value of the voltage source impedance and is equal to 199.9ȝV/ȍ. This offset can be compensated for either by using this Offset2 parameter, or by carrying out the ‘Input Adjust’ procedure (Section 6.1.9). For Dual T/C inputs, it is recommended that the ‘Input Adjust’ procedure be used instead of Offset2 as the use of Offset2 results in an offset which is non-linear over the thermocouple range.

Input filter Damping can be used to filter out noise from slowly

changing signals so that the underlying trend can be seen more clearly. Valid input values are between 0 and 60 seconds.

CJC Type For thermocouple input types only, this allows the user to select ‘None’, ‘Internal’,

‘External’ or ‘Remote 1’ to ‘Remote 4’. For Dual T/C inputs, both primary and secondary inputs use the same cold junction. None: No Cold junction compensation applied. ‘Internal’ uses the instrument’s internal cold junction temperature measurement. ‘External’ means that the cold junction is to be maintained by the user, at a fixed, known temperature. This temperature is entered in the ‘External CJ Temp’ field which appears when ‘External’ is selected. Remote 1 (2) (3) (4) means that the cold junction temperature is being measured by input channel 1 (2) (3) (4) respectively. (This must be a different channel from that currently being configured).

Ext. CJ Temp Appears only if CJC type is set to ‘External’, and allows the user to enter the temperature

at which the external cold junction is being maintained.

Sensor Break Type Defines whether the sensor break becomes active for circuit impedances greater than

expected. ‘Off’ disables Sensor Break detection. Break Low: Sensor break active if measured impedance is greater than the ‘Break Low impedance’ value given in Figure 68. Break High: Sensor break active if measured impedance is greater than the ‘Break High Impedance’ value given in Figure 68.

For mA inputs, limits are applied, such that if the process value lies outside these limits, a sensor break is assumed to have occurred. These limits are (Input lo - 4% Span) and (Input high + 6% Span). For example, for a 4 to 20mA signal, an input below 3.36mA or above 20.96mA will trigger a sensor break event.

Input sensor break detection is not supported for secondary inputs. The internal circuit acts as a ‘pull up’ on the secondary input which therefore saturates high in the event of a sensor break.

Fault Response Specifies the behavior of the instrument if a sensor break is detected or if the input is over

driven (saturated high or low). ‘None’ means that the input drifts, with the wiring acting as an aerial. ‘Drive High’ means that the trace moves to (Scale High +10%). ‘Drive Low’ means that the trace moves to (Scale Low -10%), where the 10% values represent 10% of (Scale High -

Scale Low). Sensor Break Val A diagnostic representation of how close the sensor break detection circuitry is to tripping. Measured Value The (read-only) input channel measured value before any scaling or linearization is

applied. Measured Value2 As ‘Measured Value’, above but for the secondary input. Internal CJ temp The (read-only) temperature of the internal cold junction associated with this channel.

6.4.2 Channel Trend configuration

This area allows the configuration of channel color and span.

Figure 69 Channel Trend menu and Color selection

Colour Allows a color to be specified for the channel. The Scroll key is used to enter the color

swatch page. The up and down arrows are used to scroll through the available colors, with

each color being enlarged for as long as it is ‘selected’. Once the required color, is

reached, the scroll key is used again to return to the Trend Configuration. Span Low/High Span low and high values.

Note: Break High impedance values would be used typically for sensors which have a high nominal

impedance when working normally.

Note: Trend colors and alarm settings for secondary inputs are configured in the maths channels to

which they are wired.

SPAN EXAMPLE

In an input range of 0 to 600 degrees C, the temperature range between 500 and 600 degrees is of most interest. In such a case, Span Low is set to 500 and Span High to 600 so that the instrument trends only the required part of the temperature range, effectively magnifying the area of interest.

CHANNEL CONFIGURATION EXAMPLE

A type J thermocouple is used to measure a temperature range of 100 to 200°C. This thermocouple output is transmitted to the instrument by a 4 to 20mA transmitter, for display as a value between 0 and 100%.

In Channel.Main, set the following for the relevant channel: Type = mA Units = % Input Low = 4.00 Input high = 20.00 Shunt = 250 Ohms Lin Type = Type J Range Low = 100.00 Range High = 200.00 Range Units = °C Scale Low = 0 Scale High = 100 Other items may be left at their defaults.

ROC’ (rate-of-change: rising), ‘Fall ROC’ (rate-of-change: falling), ‘Digital High’, ‘Digital

Low’. See ‘Alarm types’, below, for definitions. Status Read only. This shows that the alarm is Off, Active, SafeNotAcked or ActiveNotAcked. For

‘Auto’ and ‘Manual’ alarms only, ‘SafeNotAcked’ means that the alarm trigger source has

returned to a non-alarm state, but the alarm is still active because it has not been

acknowledged. Similarly, ‘ActiveNotAcked’ means that the source is still active and the

alarm has not been acknowledged. Always shows ‘Off’ when the alarm is inhibited (see

below). Threshold For absolute alarms only, this is the trip point for the alarm. For absolute high alarms, if

the threshold value is exceeded by the process value (PV) of this channel, then the alarm

becomes active, and remains active until the PV falls below the value (threshold -

hysteresis). For absolute low alarms, if the PV of this channel falls below the threshold

value, then the alarm becomes active and remains active until the PV rises above

(Threshold + Hysteresis). Reference For deviation alarms only, this provides a ‘centre point’ for the deviation band.

For ‘deviation high’ alarms, the alarm becomes active if the process value (PV) rises

above the value (Reference + Deviation) and remains active until the PV falls below

(Reference + Deviation - Hysteresis).

For ‘deviation low’ alarms, the alarm becomes active if the process value (PV) falls below

the value (Reference - Deviation) and remains active until the PV rises above (Reference

- Deviation + Hysteresis).

For ‘deviation band’ alarms, the alarm is active whenever the process value (PV) lies

outside the value (Reference ± Deviation) and remains active until the PV returns to within

the band, minus or plus Hysteresis as appropriate. Deviation For deviation alarms only, ‘Deviation’ defines the width of the deviation band, each side of

the Reference value, as described immediately above. Hysteresis For absolute and deviation alarms, this provides a means of preventing multiple alarm

triggering, if the process value is drifting close to the trigger value. Amount For rate-of-change alarms only. The alarm becomes active if the process value rises (Rise

ROC) or falls (Fall ROC) by more than the specified ‘Amount’ within the time period

defined in ‘Change Time’, below. The alarm remains active until the rate of change falls

below the value (Amount/Change Time) in the relevant sense. Change Time Settable to 1 second, 1 minute or 1 hour. See ‘Amount’ (above). Average Time For rate-of-change alarms only. This allows an averaging period (for the process value) to

be entered to reduce nuisance trips due to signal noise, or if the rate of change is hovering

around the trip value. Latch None: The alarm remains active until the monitored value has returned to a non alarm

state, when it becomes inactive.

Auto: The alarm remains active until the monitored value has returned to a non alarm state

and the alarm has been acknowledged. Acknowledgement can take place either before or

after the value has returned a non alarm state.

Manual: The alarm remains active until the monitored value has returned to a non alarm

state and the alarm has been acknowledged. Acknowledgement is permitted only after the

value has returned a non alarm state.

Trigger: Not enunciated, this mode is used only to initiate an action defined by user wiring

either using iTools or using the user interface. Block Alarms with ‘Block’ set to ‘On’ are inhibited until the monitored value has entered the 'safe'

condition after a start-up. This prevents such alarms from becoming active whilst the

process is brought into control. If a latching alarm is not acknowledged then the alarm is

re-asserted (not blocked), unless the alarm’s threshold or reference value is changed, in

which case the alarm is blocked again. Dwell Initiates a delay between the trigger source becoming active, and the alarm becoming

active. If the trigger source returns to a non alarm state before the dwell time has elapsed,

then the alarm is not triggered and the dwell timer is reset. Acknowledge Select ‘yes’ to acknowledge the alarm. Display returns to ‘No’.

Active Read-only. Shows the status of the alarm as ‘Yes’ if it is active, or No, if inactive. The

active/inactive state depends on the Latch type (above) and acknowledgment status of the

alarm. Always shows ‘No’ if the alarm is inhibited (below). Inactive As for ‘Active’ above, but shows ‘Yes’ if the alarm in inactive and ‘No’ if the alarm is active.

Always shows ‘Yes’ if the alarm is inhibited (below). N.acknowledged As for ‘Active’ above but shows ‘Yes’ for as long as the alarm is unacknowledged, and ‘No’

as soon as it is acknowledged. Always shows ‘No’ if the alarm is inhibited (below). Acknowledgement Fleetingly goes ‘Yes’ on alarm acknowledgement, and then returns to ‘No’. Inhibit When ‘Inhibit’ is enabled, (tick symbol), the alarm is inhibited. Status is set to ‘Off’; ‘Active’

and ‘N.acknowledged’ are set to ‘No’, and ‘Inactive’ is set to ‘Yes’. If the alarm is active

when inhibit is enabled, then it becomes inactive until inhibit is disabled, when its status

depends on its configuration. Similarly if the alarm trigger becomes active when the alarm

is inhibited, the alarm remains ‘off’ until inhibit is disabled, when its status depends on its

configuration.

6.5.2 Totalizer configuration

Totalizers allow the user to maintain a running total of any input channel, or of any maths channel. Using maths channels, it is possible to totalize combinations of input channels so that, for example, the sum of two channels or the difference between them could be totalized if required.

A totalizer is configured using Virtual Channels. This is in essence a way to convert an input signal representing a rate of change of some parameter, such as a fuel flow being measured, for example, in litres/minute into a cumulative flow. If the fuel flow is constant then, of course, the conversion would be simple, just multiply the flow rate by time and the answer comes out directly in litres. Provided, of course, that the time units of the flow rate and the time measurement are in the same units. Both need to be in Seconds, Minutes, Hours, etc. in order to get the correct answer.

If the flow rate is variable, the calculation has to be done repeatedly over the time period required and the results of the individual calculations must then be added together (totalized). In order to get reasonable accuracy it is important that the flow should be reasonably constant during each measurement period. This means that the sampling time for the measurements should be sufficiently frequent that significant changes in flow rate are not missed. If the sampling frequency is high enough, the totalization process is approximately equivalent to mathematical integration of the input signal.

The totalizer block in the FEC920 is intended to automate this process. It uses the built-in sampling rate of the FEC920 (125mSec) as the sampling period for the totalization process. In addition, it provides two separate parameters which can be used to adjust the results of the totalization process so that the output from the block is scaled in the correct units. Figure 76 shows the Main configuration parameter list when the Virtual Channel block is being configured as a totalizer.

Wiring is carried out either at the operator interface (Section 10), or in iTools (Section 9).

The totalizer equation is:

Figure 76 Typical totalizer configuration menu

Descriptor Allows the user to enter a descriptor (20 characters max.) for the totalizer. Type Select: Math, Counter or Totalizer. Operation Allows the user to enable (‘On’) or disable (‘Off’) the totalizer. PV Read-only. This is the dynamic output value of the totalizer. Status Read-only. Shows the status of the totalizer. Resolution The Resolution parameter allows the number of decimal places (up to six) to be set for the

totalized value as displayed on the instrument panel. It does not affect the resolution of

the totalization process. Up to six decimal places may be set for the totalized value. Units Allows a units string of up to five characters to be entered for the totalized value. Units Scaler Allows a units scaler to be selected. Typically this will be used to scale between unit types

rather than to influence time period.

One example of this would be when an input is measured in Litres/Minute, and Period has

been set to 1Minute. If UnitsScaler is set to 1 then the total volume will be measured in

Litres. If the volume is required in Cubic Metres then conversion of the total will be needed.

There are 1000 Litres in a Cubic Metre so the UnitsScaler should be set to 1000. This

produces an additional division of 1000 and results in a total output in Cubic Metres.

Another example would be a requirement for the output in Gallons rather than litres, still

with an input being measured in Litres/Minute. There are 4.54609 litres in an imperial

gallon so the UnitsScaler would be set to 4.54609. (For a US Gallon the figure would be

3.78541.) Low Cut Off Used to restrict the input operating range of the totalizer. Minimum value = -100 000 High Cut Off Used to restrict the input operating range of the totalizer. Maximum value = 100 000

Low Cut Off and High Cut Off are particularly important as they directly affect the totalization process. Together these two parameters define the range of valid inputs to the totalization process. If Input1 value lies between them, then the input is considered valid

and it contributes to the total for any period during which it remains valid. Negative input values are allowed and will cause the totalizer to decrease in value for negative values. The total increases with positive values.

If the input lies outside the region defined by these CutOff parameters then it will be ignored and not contribute to the total.

Many applications do not wish to use negative values and so LowCutOff would then normally be set to 0. Occasionally though, calibration errors at the low scale end could cause unacceptable errors in the total. In these circumstances, it may be necessary to consider setting LowCutOff to a small positive value.

An example where this may be needed is when a process has a very low input value for long periods of time interspersed with short periods of high input values. The cumulative effect of slightly inaccurate low input values for long periods could then reduce the accuracy of the overall total recorded.

Thoughtful use may produce an increase in the overall accuracy of the total; inappropriate use could introduce significant inaccuracy.

Input1 The value of the source. May be entered manually, or this parameter can be wired from

an external channel PV. Input1 is the input signal representing an external measurement which is in the form of Units/Time-Unit, i.e. a rate. The sampling rate internal to the block is fixed at the instrument tick rate of eight times/second, taking one sample every 125ms.

Period The Period parameter divides the signal being applied to Input1 by the number which is

needed to generate a Total PV which is scaled in appropriate time units. There is a selection of preset values available for the Period parameter. These are listed in Table 1 below. The totalizer equation works in seconds. If the totalized channel units are other than ‘per second’, a period scaler different from the default (1 sec) must be used. The ‘Period’ field presents a number of fixed periods from 0.125 seconds to 24 hours for selection.

Preset Setting this to ‘Yes’ causes the totalizer to adopt the Preset Value. The field returns

immediately to ‘No’. The totalizer can also be pre set by an external source ‘wired’ to this parameter.

Preset Value Allows the entry of a value, from which the totalizer is to start incrementing or

decrementing. The direction of the count is set by the sign of the units scaler: positive = increment; negative = decrement.

Rollover This is the rollover output which will be set for one execution cycle when the totalizer rolls

over. This output can be used to expand the range of the totalizer by wiring it to the Trigger input of a counter.

Rollover Value This is the value at which the totalizer will roll over to 0. It is configurable (default

1,000,000). When the totalizer rolls over the difference between the rollover value and the calculated output will be added to 0. Example 1: with a rollover value of 1000, a current output of 999 and an input of 5, then the output will become 4. Example 2: with a rollover value of -1000, a current output of -999 and an input of

-5, then the output will become -4.

In both examples, the Rollover output will be set for 1 execution cycle. Many applications do not require very large values to be totalized and can be scaled so

that the Rollover Value will never be reached. The instrument default value of 10^6 is generally satisfactory for these. If, however, higher values are expected, a larger Rollover value than this will have to be used. When configuring very large values the number stored on the instrument display may be slightly larger or slightly smaller. This happens because the numbers are stored in the instrument in IEEE representation as used by all computing systems to save space. The trade-off is that very large values are stored with a small inaccuracy, which increases as the value being stored increases. As an example, if a value of 9,999,999,999,999 is entered into the instrument screen as the Rollover value, it is read back on the instrument panel as 9,999,999,827,968. The inaccuracy caused by the compression amounts to 0.02 parts per million, considerably smaller than the inaccuracy associated with the input channel which is being used to generate the input to the totalizer.

Disable Allows the user temporarily to suspend totalizing action. The totalizer is toggled between

being enabled (cross symbol) and disabled (tick symbol) by means of the scroll key. The output retains the pre-disabled value until the totalizer is re-enabled, when it resumes from that value, or until the value is changed using the Preset parameter mentioned above. In the latter event, it will still be necessary to enable the totalization by setting the Disable parameter to the cross symbol again.

The selections in Bold Italic font are those which set the calculation into common time units, Second, Minute, Hour and Day (24Hours), and are probably going to be the most commonly selected. The other selections may be useful for more unusual applications.

Note: The formula linking Input1 and PV is:

PV Increment each 0.125Sec = Input1/(8*Period(Sec) * UnitsScaler). There is no reason why the Period and UnitsScaler parameters have to be used only in the

way described above, one reflecting the units used by the input channel and the other linked directly to the output units required. There may be application where they may be used in other ways. Use Table 1, which shows the divisor associated with a particular selection for Period, in combination with a custom value as the UnitsScaler to generate a custom overall divisor.

6.5.3 Wiring Example using a counter in combination with a totalizer

Figure 77 shows how a counter and totalizer can be linked in a real application using the internal (soft) wiring in iTools. See also Section 9.3.

The application is to provide a running total of power being used by a process.

Figure 77 Linking a counter and totalizer

In this example Channel 1 input is connected to a wattmeter. Totalizer VC1 uses the period parameter to set the timescale of the units to hours. The UnitsScaler is set to

1000 to set the units of the total to Kilowatt-Hours. Alarm 1 in VC1 is set as Absolute High and the Alarm Status output resets VC1 and increments the counter

VC3 by 1. Math2 1 takes the output from VC1 and converts it into MegaWatt-Hours so that it can be added to the count

(also in MegaWatt-Hours) from VC2 to present a running total value. Digital Input 1A1B is used to simultaneously reset both the count in VC2 and the total in VC1. OR 1 is used to allow VC1 to be reset either by 1A1B or by the total reaching 1000.

Note: Firmware version 5.00 uses 64 bit IEEE calculations. Inputs and outputs from the block as

wiring to and from other blocks is still in 32bit format, just like all other instrument parameters. Inside the totalizer block these are converted to 64bits and processed in the 64bit domain until their value has to be used by another block or has to be sent over comms, when it is converted back to 32bits.

6.5.4 Counter configuration

This allows the user to set up a counter to count trigger inputs (or it may be incremented from the Configuration page. The Rollover Value of the counter is configurable (default 1,000,000). Counters can be cascaded by wiring from ‘Rollover’ of one counter to ‘trigger’ of the next. Wiring is carried out from the operator interface (Section

10) or in iTools

(Section 9).

For ‘Trend’, ‘Alarm 1’ and ‘Alarm 2’ configurations please see the relevant parts of Section 6.4.

Figure 79 Typical Counter configuration

Descriptor Allows the user to enter a descriptor (20 characters max.) for the counter. Type Select: Math, Counter or Totalizer. Operation Allows the user to enable (‘On’) or disable (‘Off’) the counter. PV Read only. Shows the dynamic value of the counter. Status Read only. Reflects the status of the input channel. Resolution Allows the number of decimal places (up to six) to be defined for the channel. Units Allows a units string of up to five characters to be entered for the counter value. Low Cut Off Specifies a value below which the counter will not decrement. High Cut Off Specifies a value above which the counter will not increment. Input1 The amount by which the counter is incremented each time ‘Trigger’ goes high. The value

may be entered manually, or wired from another parameter. Negative values cause the counter to decrement.

Preset Setting this to ‘Yes’ causes the counter to adopt its Preset Value. The field returns

immediately to ‘No’. The counter can also be preset by wiring from another parameter.

Preset Val Allows the entry of a value, from which the counter is to start incrementing or

decrementing.

Trigger Setting this to 1, causes the current value of the input source to be added to the Counter

value. This function can be carried out manually, or the input can be wired from another parameter (Section 10.2).

Rollover This is the rollover output which will be set for one execution cycle when the counter rolls

over. This output can be used to expand the range of the cascade counters by wiring it to the Trigger input of the next counter.

Rollover Value This is the value at which the counter will rollover and is configurable in the same way as

the totalizer. When the counter rolls over the difference between the rollover value and the calculated output will be added to 0. Example 1: with a rollover value of 1000 and a current output of 999 and an input of 5, then the output will become 4 when the counter is next triggered. Example 2: with a rollover value of -1000 and a current output of -999 and an input of -5, then the output will become -4 when the counter is next triggered.

Disable Allows the user temporarily to suspend counting. The output retains the pre-disabled

value until the counter is re-enabled, when it resumes counting from that value. The counter is toggled between being enabled (cross symbol) and disabled (tick symbol) by means of the scroll key.

Note: In both examples, the Rollover output will be set for one execution cycle.

6.6 MODBUS MASTER CONFIGURATION

Modbus master configuration is divided into two areas: a) setting up the slave(s), including diagnostics, and b) defining the locations of the parameters to be read. Figure 80 shows an overview.

Section 5.4.7 shows the Modbus Master display page, and describes the configuration options available there.

Figure 80 Modbus Master configuration top level menus

Note: Versions 2.40 to 2.50 of the Mini8 Controller, and versions 2.70 to 3.20 of the Model 3550

controller are supported. It is not guaranteed that later software versions of these instruments will be fully compatible.

6.6.1 Slave Main menu

This allows the IP address, Unit ID and other communications parameters to be entered for Slaves 1 and 2.

Figure 81 Modbus Master Slave 1 configuration (Slave 2 similar)

Descriptor A descriptor for this instrument. For use in Modbus communications, this is not the same

as the ‘Name’ which appears in the Instrument Info configuration (Section 6.12).

Online Disabled by default (Cross symbol). Must be enabled (highlighted using the down arrow,

then edited by the scroll button) to allow the remaining configuration items to appear and to allow data transactions be processed. Setting the slave offline temporarily disables data

transactions - it does not reconfigure them. Comms Failure Active (yes) if a data item has failed to respond after all retries. IP Address The IP address of the Slave device. Unit ID The Unit Id or Modbus address to use in each data transaction with the slave device.

Limits are 1 to 255. Search Device Setting this to ‘Yes’ searches the network to see if the device with the specified IP address

and Unit ID is available. If so, the descriptor will be overwritten to indicate what type of

device has been found. Search Result The status of the selected 'Search Device' request (Searching, Available, Unreachable).

Search activity is indicated by a rotating animated display in the ‘Searching’ field. Profile A number of profiles are held within the instrument that match a selection of known

devices. If the device is ‘known’, its type, model number etc. is displayed. If the device is

unknown, ‘3rd Party’ appears instead. Retries The number of times (0 to 3) to re-send a data transaction to the device if no response is

received within the configured timeout period (below). Timeout The timeout period for each Modbus transaction in ms. Max Block Size The maximum number of registers (16bit words) that a single data transaction is permitted

to contain. High Priority The interval rate between each high priority data transaction. Default = 0.125 second. Medium Priority The interval rate between each medium priority data transaction. Default = 1 second. Low Priority The interval rate between each low priority data transaction. Default = 2 seconds.

PRIORITY LEVELS

Three levels of update rate can be entered for use in data configuration (Section 6.6.3), to define how often a value is read or written. In order to optimize performance, it is recommended that the slowest rate consistent with requirements be selected. The intervals are selected from a scroll list see Figure 81 above.

6.6.2 Slave Diagnostics menu

Figure 82 Diagnostics menu

Actual High The high priority rate that this slave is actually running at. This can never be faster than

the high priority rate that was configured for this device (Slave Main menu, above), but if the master is heavily loaded the rate may be lower than that specified.

Actual Medium The medium priority rate that this slave is running at. This can never be faster than the

medium priority rate that was configured for this device (Slave Main menu, above), but if the master is heavily loaded the rate may be lower than that specified.

Actual Low The actual low priority rate that this slave is running at. This can never be faster than the

low priority rate that was configured for this device (Slave Main menu, above), but if the master is heavily loaded the rate may be lower than that specified.

Device Status The status of the last transaction to this slave.

Success: The transaction was successfully actioned by the slave device. Timeout: There was no response from the slave device to a given request within the

configured time. Illegal Address: The request to the slave device contained an invalid Modbus address.

The address may be for a read only parameter. Illegal Value: The request to the slave device contained invalid data for the specified

parameter. Bad Sub: The sub function code in the request was invalid. Idle: This data item is currently idle and not communicating with the slave device.

Note: Diagnostic values are reset on power up.
