USB Device Precautions
Note: The use of U3 USB Flash drives is not recommended.
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 3 metres (10 ft.).
.
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.

nanodac™ Recorder / Controller Cybersecurity
Cybersecurity
What’s in this Chapter
This chapter outlines some good practice approaches to cybersecurity as they relate
to use of the nanodac instrument, and draws attention to several nanodac features
that could assist in implementing robust cybersecurity.
Introduction
When utilising the nanodac in an industrial environment, it is important to take
‘cybersecurity’ into consideration: in other words, the installation’s design should aim
to prevent unauthorised 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).
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.com.
Security Features
Principle of Secure by Default
HMI Access Level / Comms Config Mode
Typically, an industrial controller such as the nanodac 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).
The sections below draw attention to some of the cybersecurity features of the
nanodac.
Some of the digital communication features on the nanodac 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).
As described in Login (page 49), the nanodac device features tiered,
password-restricted user access levels, so that available functions and parameters
can be restricted to appropriate personnel.
Note: User accounts of any access level require a password, otherwise they will not
be available for selection.
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.

www.GlobalTestSupply.com
Page 17
Cybersecurity nanodac™ Recorder / Controller
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, a password is required to enter Operator level. Passwords can be configured
either at Supervisor level or at Engineer level.
If the Auditor feature is enabled, the Operator user is pre-configured as ‘User 1’. See
next section for details.
Customizable Users
Overview
A total of 25 customizable user accounts are available. With the exception of ‘User 1’
which is pre-configured to replace the ‘Operator’ user account, the remaining 24 are
disabled by default and require the ‘Login Disabled’ permission to be enabled and a
unique password provided.
Each user account can automatically inherit the ‘Logged Out’ access level, however
the user can further choose to inherit the permission sets from any of the following
base users:
• Operator (these permissions can be individually configured)
• Supervisor (inherits as a set)
• Engineer (inherits as a set)
The following example demonstrates the number of user account types that can be
configured.
• 24 Operator Users + 0 Supervisory Users + 1 Engineer User, or
• 23 Operator Users + 1 Supervisory User + 1 Engineer User, or
• 10 Operator Users + 10 Supervisory Users + 5 Engineer Users, or
• 13 Operator Users + 9 Supervisory Users + 3 Engineer Users, etc.
Username
The username for each user can be up to 20 characters in length. Typically, only the
first 12 characters are displayed in scroll lists (such as when logging on) due to
space. When logging in, the user account number (1 to 25) is prefixed to the
username so that each name is unique by default.
Password
The password for each user can be up to 20 characters in length, and should contain
a selection of numbers, letters, uppercase, lowercase, etc. to provide a strong
password for enhancing cybersecurity.

Configurable parameters per user
The following parameters are configurable for each user. Refer to "User Accounts
(Auditor)" on page 107 for further details:
Permission Description
Batch Control Yes = Control batches via batch control page
Ack Alarms Yes = Acknowledge alarms in the alarm summary screen
Demand Archiving Yes = Access to the demand archiving screen
Login Disabled Yes = Disable this account
Signing Yes = This user will appear in the list when required to sign
for an action
Authorising Yes = This user will appear in the list when required to
authorise an action
Archive Interval Yes = Modify the archive interval rate
Loop Control Yes = Change the mode, manual OP in control loop
screens
Supervisor Access Level
Engineer Access Level
HMI Passwords
Program Mode Yes = Change the mode of programs
Program Edit Yes = Edit programs
Program Store Yes = Store programs
Supervisor Yes = Inherits Supervisor user access level (mutually
exclusive with Engineer)
Engineer Yes = Inherits Engineer user access level (mutually
exclusive with Supervisor)
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).
This allows full access to all areas of the recorder configuration.
When entering passwords via the HMI, the following features help protect against
unauthorised 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.
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
Page 19
Cybersecurity nanodac™ Recorder / Controller
• 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.
Ethernet security features
Ethernet connectivity is available on the nanodac. The following security features are
specific to Ethernet:
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 nanodac 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.
Broadcast Storm protection
Configuration backup and recovery
Memory Integrity
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 nanodac 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.
Using the iTools software, you can ‘clone’ a nanodac 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.
When a nanodac 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.
Firmware
From time to time, to provide new functionality or address known issues, Eurotherm
may make new versions of the nanodac firmware available.
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
Page 20
nanodac™ Recorder / Controller Cybersecurity
This firmware may be downloaded from the Eurotherm website, and transferred to a
nanodac instrument in the field, via a USB memory stick (or FTP server).
CAUTION
NON-SCHNEIDER ELECTRIC FIRMWARE
There is a potential risk that an attacker could upgrade a nanodac with non-genuine
firmware that contains malicious code. To mitigate this potential risk, genuine
nanodac 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.

Supported Protocols and Threat Mitigations
The nanodac 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.
FTP Client
An external FTP client can access the FTP server on the instrument. This FTP server
has a remote username and password for each of the users (that will need
configuring). Passwords can be modified and additional users can be added with
configurable remote usernames 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.
FTP Server
ICMP (ping)
DHCP
Up to two external FTP servers can be configured. The nanodac will then connect to
these servers as an FTP client and push archive files to the servers.
Threat mitigation as for FTP Client.
The nanodac 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.
The nanodac 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.
SNTP
The nanodac 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.

www.GlobalTestSupply.com
Page 22
nanodac™ Recorder / Controller Cybersecurity
ModBus
The nanodac 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).
HTTP (Web Server)
To mitigate threats:
1. Physically protect access to subnet(s) in use.
2. Firewall to block TCP port 80.
UHH Navigator
To mitigate threats:
Ethernet IP
BACnet
Decommissioning
1. Physically protect access to subnet(s) in use.
2. Firewall to block TCP port 50010.
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.
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.
When a nanodac instrument is at the end of its life and being decommissioned,
Eurotherm advises reverting all parameters to their default settings using the
Engineer Password ‘ResetConfig’ or via iTools (see "Security menu" on page 98 and
"iTOOLS" for instructions). This can help to protect against subsequent data and
intellectual property theft if the controller is then acquired by another party.

Installation Requirements
NOTICE
Safety requirements for permanently connected equipment state:
1. A switch or circuit breaker shall be included in the building installation.
2. The switch/circuit breaker will be in close proximity to the equipment and
within easy reach of the operator.
3. It shall be marked as the disconnecting device for the equipment.
Note: Recommended external fuse ratings are: 2A Type T 250V.
Termination details
The screw terminals accept single wires in the range 0.21 to 2.08mm2 (24 to 14
AWG) inclusive, or two wires each in the range 0.21 to 1.31mm2 (24 to 16 AWG)
inclusive. Screw terminals should be tightened to a torque not exceeding 0.4Nm
(3.54lb in).
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.
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 analogue 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.
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 "Input adjust" on page 103. Because of this offset, the dual
thermocouple input option is not suitable for AMS2750D applications.
Soft wiring is described in "iTOOLS".
Maths channels are described in "Maths channel configuration" on page 133.
Channel configuration is described in "Channel Main" on page 123.
Input adjust is carried out as described in "Input adjust" on page 103.
Sample Rate
For dual input channels, both primary and secondary sample rate is reduced to 4Hz
(250ms) from the normal 8Hz (125ms).

Installation nanodac™ Recorder / Controller
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.
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
"Channel Main" on page 123 for further information.
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’.
Modbus Master communications
EtherNet/IP
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.
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.

The operator interface consists of a display screen and four push buttons.
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 "Display Modes" on page 52 below; configuration is
described in "Configuration".
In display mode, the screen is split horizontally into three areas (Figure 6):
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.

Navigation Pushbuttons
Figure 7 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 7) 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 "iTOOLS".
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 ("Text Entry" on page 89) and number pads used to enter text or numeric
strings.
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.
(Use the Page button with the down arrow to access hidden text at the bottom of the

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
"Configuration".
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 "Security

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

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 use-
ful life, or that it is missing or is completely exhausted. Im-
mediate battery replacement is recommended ("Appendix
C: Reference", "Battery" on page 431).
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 to slow
The archive rate is too slow to prevent the internal memory
from overflowing. The recorder effectively switches to ‘Au-
tomatic’ ("Archiving" on page 111) to ensure that data is
not lost.
FTP Primary Server Failure
This error occurs if the recorder fails to establish connec-
tion 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. Ar-
chiving area of configuration ("Archiving" on page 111).
FTP Secondary Server Failure
This error occurs if the recorder fails to establish connec-
tion with the secondary server, after two attempts. Primary
and secondary server details are entered in the Net-
work.Archiving area of configuration ("Archiving" on
page 111).

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 pro-
tected; archiving has been disabled; archiving rate too
slow.
Media archiving to slow
The archive rate is too slow to prevent the internal memory
from overflowing. The recorder effectively switches to ‘Au-
tomatic’ ("Archiving" on page 111) 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 attempt-
ed.
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 ‘mem-
ory 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 synchronisation failure
Instrument time has failed to synchronise with SNTP serv-
er. If more than 5 ‘Time change events’ occur within 24
hours a ‘Time synchronisation failure’ alarm is set. The
alarm occurs 24 hours after the first event. Once synchro-
nisation is re-established, the alarm self- clears within 24
hours. A ‘Time change event’ occurs whenever the record-
er 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 pre-
vent 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 "Go to
View" on page 43 or in the Channel configuration area ("Alarm 1 menu" on page 128)
if the user’s access permission is appropriate.

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
"Trend History" on page 87.
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.
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 "Text Entry" on page 89, or "iTOOLS"
described in "iTOOLS". 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 "Text Entry"
on page 89. 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.
Note: Note: Each note can contain up to 100 characters.
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.

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.Ar-chive area of configuration described in "Archiving" on page 111. 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 im-
mediately, 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.

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 ("Archiving" on page 111).
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 C, "Setting Up
An FTP Server Using Filezilla" on page 431 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 C, "Setting Up An FTP Server Using Filezilla" on
page 431 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, totaliser, 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.
*Suitable instruments are connected instruments, the archive files of which have the
suffix ‘.uhh’.

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 are required for the additional 25 user accounts, when the Auditor feature
is enabled. Failed login attempts are recorded in the history. It is recommended that a
strong password, that is difficult to guess is used. Failed login attempts are recorded
in the history.
Note: User accounts of any access level require a password, otherwise they will not
be available for selection.
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.
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, a password is required to enter Operator level. Passwords can be
configured 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).
Note: 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). The
password for the Supervisor level must be configured, if the access level is to be
used (and can be changed) in the Instrument area of configuration, either at
Supervisor or Engineer access level, see Security menu (page 98). It is
recommended that a strong password be used.
When the Auditor feature is enabled, it is regarded as best practise that the
Supervisor level is not used at all. This can be enforced by disabling the Supervisor
level altogether (refer to the ‘Sup Log Disabled’ parameter in Security menu
(page 98). With the Supervisor access level 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 Engineer
password must be configured at initial start see Introduction - Initial Setup (page 33)
and can be changed in the Instrument area of configuration by the existing Engineer
access level user, see Security menu (page 98). It is recommended that a strong
password be used.
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.
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 "User
Accounts (Auditor)" on page 107 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.

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 ("Display configuration" on page 94). 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

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 ("Group Trend

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.
Horizontal Trend Mode
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 behaviour can
be enabled/disabled from the top level menu ‘Faceplate Cycling (Off)’ item described
in "Faceplate Cycling on/off" on page 46.
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.
This view is similar to the vertical trend mode described in "Vertical Trend Mode" on
page 52 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.

Figure 31 Access to the program editor
As can be seen from the figure above, the initial Program Edit page is divided into
two areas - the top part contains program details; the lower part (Figure 33) contains
individual segment details. The editable items that appear in the program details area
depend on the features enabled in the Programmer Features configuration menu
("Programmer Features menu" on page 172).
Note: Access to some program operations is restricted to users with the correct
access level, as defined in the ‘Prog Mode Access’, the ‘Prog Edit Access’ and the
‘Prog Store Access’ parameters in the Programmer. Set Up area of configuration
described in "Programmer Setup menu" on page 175. Alternatively, if the Auditor
feature is enabled, individual users can be assigned access to the Program Mode,
Program Edit and Program Store functions. Access to some items also depends on
whether or not the program is running.

Holdback pauses the program (freezes the Programmer setpoint (PSP) and the time
remaining parameters) if the difference between the Process value (PV) and the PSP
exceeds a user-specified amount (Holdback value). The program remains paused
until the PV returns to within the specified deviation. In ramp or step segments,
holdback indicates that the PV is lagging the SP by more than the specified amount
and that the program is waiting for the process to catch up. In a dwell segment,
holdback is used to guarantee that a work piece stays at set-point within a specified
tolerance for the specified dwell duration.

‘Ch1(2) Time’ or ‘Ch1(2) Rate’, below.
Dwell. The setpoint is maintained at its current value for
the period defined in ‘Duration’ (see below).
Step. A step segment allows a step change to be entered
for the target set-points Ch1 TSP and Ch2 TSP.
Wait. A wait segment causes the program to wait for a cer-
tain event to occur before continuing. See ‘Wait For’, be-
low.
Go Back. A Go Back segment allows a specifiable number
of iterations to be performed of a group of segments. This
could be used, for example, to cycle an entire program by
having a Go Back segment immediately before the end
segment and specifying segment 1 as the ‘Go Back To’
point. Setting ’Cycles’ to ‘Continuous’ causes the program
to loop indefinitely, until interrupted by the user. ‘Nested’
loops are not permitted i.e. ‘Go Back’ is not available as a
segment type for segments inside an existing GoBack
loop.
End. The final segment of a program allows the user to se-
lect ‘Dwell’ or ‘Reset’ as the action to be taken at the end
of the program (see ‘End Type’, below).
Ch1(2) TSP Target setpoint. The value that Ramp or Step segments
seek to attain, for channel 1(2).
Ch1(2) Rate For Ramp Rate segments, this specifies the speed at
which the process value ramps towards the target, for
Channel 1(2). The ramp units (per second, per minute, per
hour) are set in Ch1(2) ramp units described above.
Ch1(2) Time For Ramp Time segments, this allows the user to specify
the time to be taken by the segment for the process value
to reach the target.
Duration For Dwell segments, this allows the entry of the time for
which the segment dwells.
Go Back To For ‘Go Back’ segments, this defines the number of the
segment to which the program is to return.
Cycles The number of times the ‘Go Back’ instruction is to be car-
ried out. If set to ‘Continuous’, the program continues until
the user intervenes to stop it.
End Type Allows the user to select the action to be taken at the end
of the program:
Dwell: the set-point is maintained indefinitely and event
outputs remain at their configured state.
Reset: the set-point reverts to the value used by the control
loop before the program was started and the event outputs
return to their default states.
Wait For Digital High: Wait segments can be configured to wait for
‘Wait Digital’ to go ‘high’ before allowing the program to
continue.
Analog 1(2): The segment waits for ‘Wait Analog1(2) to
meet an Absolute High or Low, or Deviation High or Low
condition before allowing the program to continue.
Analog Both: As Analog 1(2) above, but waits for both
Channels’ conditions to be true before continuing.
Note: ‘Wait Digital’, Wait Analog 1’ and ‘Wait Analog 2’ parameters are configured in
the Programmer.Set Up menu described in "Programmer Setup menu" on page 175.
Ch1 Wait Select ‘Abs High’, ‘Abs Low’, ‘Dev High’ or ‘Dev Low’ as the
wait criterion for channel 1. Appears only if ‘Wait For’
(above) is set to ‘Analog 1’ or ‘Analog Both’.
Ch2 Wait Select ‘Abs High’, ‘Abs Low’, ‘Dev High’ or ‘Dev Low’ as the

Future Trend Display Mode
If enabled in Instrument.Display configuration ("Display configuration" on page 94),
this allows the user to view the actual value of the PSP alongside the expected value,
so the two can be compared to see how the process is performing. Future trend is an
enhancement of the horizontal trend mode, with the display being divided into two
parts, with the instantaneous current value located at the divide, with past trends to
the left and the next few program segments to come, to the right.
NOTES:
1. For the future trend mode to appear, the programmer must be wired to the loop
or advanced loop feature.
2. Both historic and future trends move from right to left with the present anchored
at the screen centre.
3. The amount of history and of future trending displayed on the screen depends on
the trend interval set in Group.Trend configuration ("Group Trend configuration"
on page 117).

Program Load - Quick Access
From firmware version V5.00 and above a quick selection of an internally stored
program may be made directly from the Program Summary page. The programmer
must be in Reset. Press and hold the scroll key for two seconds. The page will go
immediately to the file explorer page with the ‘User’ drive selected and the
‘Operation’ parameter set to ‘Load’. The first program file will be selected (assuming
different programs have been configured). Use the Up/Down keys to select the
required program followed by the scroll key to load it.
If the selected file cannot be loaded (for example, the programmer file is for a
different number of channels) then an error message is shown on the file explorer.
The Quick Access to load mode adheres to the access security settings set in
configuration mode - Programmer set up ("Programmer Setup menu" on page 175).
Note: Quick load is disabled when in Edit mode. This is indicated by the highlighted
parameter showing the raise/lower symbol to the right of its value.
Figure 38 Program load display
Program Load via a Program Number
This feature has been added to firmware versions V5.00 and above. To allow a
program (stored as a file) to be loaded, either via a BCD switch, wired to a set of
digital inputs, or via a single comms transaction, it is necessary to prefix the program
name with a program number in the range 01 to 99. For example, 01kiln1.uipz,
01furnace.uipz, 02kiln2.uipz, 03kiln3.uipz etc. The program name can consist of up
to 18 characters. Note that program numbers 1 to 9 must be entered as 01 to 09
otherwise they will not be recognised by the switch or via comms. On value change of
the program number, the first program file with the prefixed number in the
instrument’s internal User drive (listed lexicographically) will be loaded. In the above
example if program 01 is selected, 01fur-nace.uipz will be loaded, 01kiln1.uipz will
not be loaded using the BCD switch or through comms. It can, of course, be loaded
manually.
If no program number is prefixed it is not possible to load the program via the BCD
switch or via comms. It is, however, still possible to load the program by selecting the
file as described in the previous section.

BCD Switch
Note: When a BCD switch is turned from its current value to another value,
intermediate switch positions may be seen on the inputs of the BCD function block
and could potentially be used by subsequent blocks wired from the BCD input. A
Settle Time parameter has been introduced which will in effect filter out these
intermediate values by applying a time in which the inputs can settle before their
converted decimal value is seen on the output parameters of the block. The Settle
Time can be set from 0-10 seconds with a default of 0s i.e. no filtering as in previous
firmware versions. The BCD block is described in "BCD Input" on page 214.
Example BCD Switch Wiring
Figure 39 shows an example of digital input channels soft wired to the BCD function
block using iTools.

Operation
A sterilising cycle cannot be initiated whilst the unit is in Configuration (Engineer)
mode. A steriliser cycle is started by setting its relevant ‘Start’ input to ‘Yes’ for the
duration of the cycle. The cycle waits (status ‘Waiting’) until input 1 reaches its
setpoint, at which point the cycle enters the equilibration period (status
‘Equilibration’), and remains there until all the configured inputs are valid. The cycle
then enters the sterilising period and stays in this mode until the sterilising period has
expired (status ‘Passed’) or until one of the inputs becomes invalid (status ‘Failed’)
for longer than its configured ‘Failure Dwell’ time.
Note: The cycle stops (status ‘Failed’) if the trigger source is removed.
Terminology
Holding time Most operating cycles have a stage in which the load must
be exposed to sterilisation conditions for a specified length
of time, known as the ‘Holding time’.
Equilibration time The holding time (above) is preceded by a period during
which, although the sterilising condition is present in the
chamber, the load has not yet attained that temperature
due to its thermal inertia. ‘Equilibration time’ is defined as
the time between the attainment of sterilisation temperature in the chamber, and the attainment of that temperature in all parts of the load.
Bands For steam and dry heat sterilisers, sterilisation conditions
are specified by a sterilisation temperature band, defined
by a minimum acceptable temperature (known as the sterilisation temperature) and a maximum allowable temperature. A sterilisation band is normally quoted for each
steriliser type.
Find Quality Products Online at: sales@GlobalTestSupply.com
www.GlobalTestSupply.com
Page 71
Operation nanodac™ Recorder / Controller
Beacons
There are four input status beacons near the top right hand corner of the display, one
for each input. During equilibration, the beacons are flashing red for inputs that have
not attained the Target setpoint, and go green when the target setpoint is reached,
remaining green even if the input value rises above the Band High value The
beacons revert to red if input falls below* the target setpoint. During sterilisation, the
beacons go red for any input whose value rises above Band High or falls below*
setpoint for a duration exceeding the configured ‘Failure Dwell’ period. Beacons are
black for inputs that are configured as ‘Off’.
* ‘rises above’ for input types ‘Falling Pressure’ or ‘Fall Air Detect’.
Displayed Information
Cycle A five-digit counter to indicate the total number of cycles
started.
Status Wait start: The initial state at power up. This status re-
mains until the first cycle is initiated Waiting: Waiting for input 1 to reach its target setpoint. The cycle then enters
Equilibration. Equilibration: Currently in the equilibration
period, during which the cycle waits until all inputs have
reached sterilisation conditions.
Sterilising: Currently in the decontamination phase.
Passed: The cycle has completed successfully.
Failed: The cycle has failed either through one or more inputs becoming invalid, or because the ‘Start’ signal was removed. Test cycle: A test cycle is in progress.
Remaining The sterilising time remaining for the current cycle. Display
field is replaced by ‘Target Time’ (below) when the cycle is
not running.
Target time The intended sterilisation time. This can be configured by
operating the scroll button twice (once to highlight the field,
and again to enter edit mode), and then using the up
and/or down arrows to edit the time. Use the Scroll button
again to quit edit mode, and the page key to ‘unhighlight’
the field.
Replaced by ‘Remaining’ (above) when the cycle is run-
ning.
Equilibration The equilibration time period for the current cycle.
Sterilising The time for which the load has currently been at sterilisa-
tion conditions.
Total Cycle The elapsed time since the initiation of the current cycle.
This time increments from the time the cycle is triggered
until the time the trigger is removed.
Input values Temperature are required in °C; pressure inputs in mBar.
If necessary, maths channels and user values can be used
to convert from other units (see ‘Note’ overleaf).

NOTES:
1. For temperature inputs in most applications, the Setpoint value is the same as
the Band Low value. For the sake of clarity, this is not as shown in the figure
above.
2. For the sake of clarity all four inputs in the figure above are shown with the same
Band High, Band Low and Setpoint value. This would not be unusual for
temperature units, but the pressure input would normally have a different set of
values from temperature inputs.
3. Band High and Band Low are effective only during Sterilisation phase.
Application Details
Figure 43 shows a typical steriliser application, with temperature and pressure
signals from the sterilisation chamber being applied directly to the rear terminals of
the controller/recorder, and control signals connected from the controller to both the
chamber and the controller/recorder.

Analogue inputs 1 to 3 receive signals from temperature transducers (typically
thermocouples) within the chamber. These inputs are internally connected to
channels 1 to 3 respectively, allowing transducer type, ranges, alarms, etc. to be
configured ("Input Channel Configuration" on page 123). Inputs are assumed to be
degrees Celsius (see Note).
The pressure transducer is connected to channel 4 and can be configured in the
same way. The input is assumed to be in milliBar. Other pressure inputs should be
converted using virtual channels (see Note).
PV1 to PV4 in the Steriliser configuration is software wired (Section 9) to Ch 1 to Ch4.
Start cycle input and the ‘Running Output’ and ‘Passed Output’ signals are software
wired to suitable DIO terminals, for connection to the Controller.
Note: For Fahrenheit inputs, use one virtual channel to subtract 32, and a second to
divide the result by 1.8 (where 32 and 1.8 can be configured as user values). Similar
techniques should be used to convert pressure input units if necessary.
Test Cycles
A ‘Test’ cycle is initiated by initiating a 121°C cycle and a 134°C cycle simultaneously.
A test cycle allows the user to check actual performance against expected
performance.
F0
F0 is a means of calculating ‘equivalent time at sterilising temperature’ for
temperatures below, at and above sterilizing temperature, using the equation below.
Where:
Sterilisation time Depends on the application, typically 15 minutes at Ts =
121°C
Temp The value of the temperature measuring input.
Ts Desired Sterilising temperature.
Z Temperature interval representing a factor-of-10 reduction
in killing efficiency. Z = 10 for steam sterilising (F0), or
Z=20 for dry heat sterilising (FH). Z = 10 for thermal disin-
fection (A0).
To ensure that steriliser loads which contain materials with different thermal inertias
are thoroughly sterilised, a number of sensors are located within the load. The F
value should be calculated using the sensor closest to that part of the load which has
the highest thermal inertia. For maximum accuracy, the temperature sensor should
be calibrated and the input adjust function used to compensate for any inaccuracy
found.
F0 calculation examples
For all the examples following, the following are assumed: Sterilisation time = 15
minutes; Sterilisation target temperature =121°C and Z = 10.
1. For an actual sterilising temperature of 111°C.

Which means that 15 minutes at 111°C is equivalent to 1.5 minutes at 121°C.
2. For a sterilising temperature of 121°C.
Which means that the sterilising temperature is ideal (by definition).
1. For a sterilising temperature of 124°C.
Which means that 15 minutes at 124°C is equivalent to nearly 30 minutes at 121°C.
Normally sterilising temperatures would not remain constant at temperatures below
or above the target value, so the above equations are illustrative only of the facts:
1. Temperatures below the target have some killing efficacy.
2. Temperatures above the target value have a greater killing efficiency, so
that the sterilising time can be reduced.
In order to calculate the value dynamically, the instrument uses the equation:

Promote list
This display page allows the user to display up to 10 of the parameters that appear
anywhere in the operator interface. The parameters can be selected only by using
iTools, as described below.
NOTES:
1. ‘Promote List’ must be enabled (in ‘Instrument.Display’ configuration), before it
appears in the ‘Go to View’ list.
2. There are more parameters visible in iTools than appear at the operator interface.
If non-operator interface parameters are selected for inclusion in the promote list,
they do not appear.
3. If parameters which appear only in certain circumstances are selected, then they
appear in the promote list only when they appear in the Operator interface. For
example, a channel PV is not visible unless that channel is enabled (i.e. it is not
‘Off’).
Parameter Selection
1. Open iTools and scan for the instrument, (see "iTOOLS").
2. Once the instrument has been found, stop the scan. When the instrument has
synchronised, click on the ‘Access’ button near the top of the display to set the
unit into configuration mode (a password may be required).
3. Click on the ‘+’ sign to the left of the Instrument folder in the tree list (left-most
pane) to expand the folder. Double-click on ‘Promote List’, to display the Promote
list in the main pane. The list contains 20 entries, 1 to 10 being for parameters, 11
to 20 being available to the user to add descriptors for parameters 1 to 10
respectively.
4. Expand further folders, as necessary, to access the required parameters, and
click-drag these parameters into the promote list. Enter a descriptor for the
parameter if the default is not as required. As each parameter is dragged into the
list, it appears in the Promote list.
5. If the parameters are modified at the operator interface, the changes are
reflected in iTools, and vice-versa.
6. Once all the parameters have been added, it is recommended that the Access
button be used to quit configuration mode, as otherwise it will not subsequently
be possible to quit from the operator interface.

Modbus Master display mode
This display mode consists of two pages, as shown in Figure 47.
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 6.10. 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 grey,
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.
Page two contains the IP address of the Modbus master and of any slaves connected
to it, together with some diagnostic information, as described in ‘Ping Details’, below.

Ping Details
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 coloured 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
("Modbus Master Configuration" on page 182).

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 50 shows this (using the nanodac as the client) in graphical
form, using just a few parameters (there can be up to 50 in each table).
Figure 50 Input/Output table entries
NOTES:
1. Channel values from the Server can be ‘wired’ into nanodac 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 "Maths channel
configuration" on page 133).
2. Inputs and outputs would normally be given suitable descriptors (e.g. ‘Reset
timer’ instead of ‘Channel.1.Alarm1’).
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.

nanodac™ Recorder / Controller Operation
Synchronised
Not synchronised
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’. "iTOOLS" 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.
Note: The client/server and the PC must all be on the same network.
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 synchronise. (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 synchronised, 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.

Explicit Data
As shown in Figure 53, 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 53 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 54, 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
nanodac server, and it can be seen from the table in "Parameter List" on page 232
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 "Parameter
List" on page 232 it can be seen that the recording status is ‘Recording enabled’.
Note: The nanodac supports only 16 bit data types for reading and writing of explicit
messages.

Find Quality Products Online at: sales@GlobalTestSupply.com
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 "Ethernet/IP Configuration" on page 189) 30 input and 30 output tags become
available to the user via iTools (Figure 55).
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.

Trend History
Figure 55 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.
NOTES:
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.
2. Input data direction is always to the nanodac: in server mode input data is written
to the nanodac from the client in client mode, input data is read by the nanodac
from the server device.
3. Output data direction is always from the nanodac: in server mode output data is
written to the client from the nanodac in client mode, output data is read by the
server from the nanodac.
Entered from the top level menu ("Introduction" on page 25), 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
("History Options Menu" on page 89) and on the recording interval selected in Group
Recording configuration ("Group Recording configuration" on page 117). 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

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 summary page.
Note: Operating the page key from the History menu causes a return to the history
display.
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 58 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 push buttons 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.
The backarrow key is used as a back space key - i.e. it deletes the character to the
left of the cursor position. The ‘Del’ key deletes the character to the right of the
cursor.
Note: Leading and trailing space characters are automatically removed from text
strings.

page 387 provides further details.
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 the
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 communications, all floating point parameters that are read via
scaled integer communications 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.

Upgrade
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.
Note: After a firmware upgrade the Engineer password must be configured to allow
any further operation, see Engineer Password - Configuration (page 33). All user
accounts require an associated password.
CAUTION
INOPERABLE EQUIPMENT
Power must not be removed from the unit whilst upgrade is in progress.
The memory stick must not be removed whilst upgrade is in progress.
Removal of the either of the above whilst an upgrade is in progress, will cause
permanent damage to the unit.
Failure to follow these instructions can result in injury or equipment
damage.

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.

can be edited here, if required, by entering an alternative
of up to 20 characters (Notes no.1).
If ‘ResetConfig’ (case sensitive) is entered as the Engineer
Password, the ‘Default Config.’ field appears allowing the
instrument default configuration to be restored (Notes no.
2).
Supervisor Pass A password of up to 20 characters must be entered here to
protect Supervisor level access.
Operator Pass A password of up to 20 characters must 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 - all configured user accounts must have an associated password, making them available for selection.
Note: User accounts, of any access level require a password, otherwise they will
not be available for selection.
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 "Interface" on page 110)
and the instrument’s firmware Version (Instrument.info
menu "Info menu" on page 96). The password is MAC address dependent so that it cannot be used on any other instrument.
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.
Feature2/3 Pass Similar to ‘Feature Pass’ above, but for additional features.
Comms Pass Enables/disables password security for external communi-
cations (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.
NOTES:
1. It is recommended that only characters that 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.
2. Restoring factory default configuration can also be carried out in iTools, using the
Engineer password ‘ResetConfig’ and selecting Default Config to ‘Yes’.
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 passcode 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 pa-
rameter changes, operator alarm acknowledgements, and
cloning status changes are recorded in the history. Note

change. However, the fact that a clone has been loaded
will be written to the history by the audit trail. This field ap-
pears only if the Auditor feature is enabled.
Signing When enabled (set to ‘Yes’), if a user tries to enter a sign-
able 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 67 Signing dialog
Authorisation When enabled (set to ‘Yes’), similar to the Signing param-
eter above, an additional user (the authoriser) will need to
enter their password to approve the operation. Other than
the built-in Engineer or Supervisor accounts, an authoriser
will need to have Authorising permissions assigned to him
or her. Refer to section User Accounts (Auditor) to assign

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 coun-
ter is reset when the password is changed. When the
password expires, it will not work any more. The engi-
neer’s password never expires so as not to block all ac-
cess. 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 ac-
count’s password will expire. These are read-only and can-
not 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 ‘ResetConfig’ has been entered
as the Engineer Password. Selecting ‘Yes’ Causes the in-
strument to restart with default configuration (i.e. the in-
strument ‘cold starts’). See Note 2 above.
Note: After a cold start (returned to default configuration) the Engineer password
must be configured to allow any further operation, see Engineer Password -
Configuration (page 33). (All user accounts require an associated password).
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 ("Save/Restore" on page 102).
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.
2. Make up to 100 parameters that are read/write in Supervisor access level, read
only when the instrument is OEM locked.
Examples of how to set up OEM security are given in the iTools ("To Set Up OEM
Security" on page 376).
