INTRODUCTION

Pakscan 3 is a complete field network control system from Rotork. With the addition of a wireless (P3W) network the user now has the choice of proven current loop technology of the Pakscan IIE system or the flexibility of a meshed wireless network. The P3W master station is supplied with a P3W Coordinator module; this module is powered by the master station and facilitates the communications between the master station and the wireless network. Most types of Rotork actuators can be connected to a Pakscan current loop provided they are fitted with the necessary field unit. Information on the respective actuator field units can be found in the appropriate manuals. In this guide, the type of actuator is not considered, though reference is made to both the integral and IQ actuator types of field unit. The type of field unit does not affect the setting up of the system. The IQ and IQT range of actuators integrate fully with the wireless network. The network range can be extended using a P3W Repeater module, this module is externally powered and it extends the network range by receiving and retransmitting network messages. Other actuators or devices can be added to the wireless network using a Pakscan 3 Wireless Modbus Adaptor (P3W WMA). This module is very similar to the P3W Repeater, but has a RS-485 serial port for communication. The Pakscan 3 master stations are delivered either as loose items for mounting by the user, or contained in an enclosure provided by Rotork. The master station will generally be either a single unit, or a hot standby pair. This manual provides a guide to setting up the Pakscan master, the various P3W Wireless modules, the loop communications, wireless communications, and the host connections for the most commonly found applications.

A master station fitted with the wired network only requires the PS720 module that fits in to the back plane. A master station fitted with wireless requires a module to be fitted to the back plane (in option

1) and connected to this module, a P3W coordinator module (PS722).

1. Mounting and Connecting the Master Station

Issue 06/15 Publication PUB059-002-00 9 of 136

1. MOUNTING AND CONNECTING THE MASTER STATION

The Pakscan 3 master station (single or hot standby) provides front access for all the user connections, including power feed and the field network connections – either loop wires to the Current Loop module (PS720) or network connection to the P3W coordinator (PS721 and PS722). The host communication links use plug in D-type connectors for the serial communications and RJ45 connections for the Ethernet links.

 The field wiring for the current loop, P3W coordinator and the master station alarms are taken

to screw terminals on plug in connectors that are fitted from below their appropriate module.

 Power wiring is connected using an IEC connector in the bottom of the master station module

PS710. Two connections are required for a hot standby system.

 Serial communications (RS-232 or RS-485) plug into 9 way female D-type connectors on the

front of the mounting chassis.

 Ethernet connections use RJ45 connectors on the bottom of the master station module

PS710. The connector on the front is intended for connection to a service laptop computer.

1.1 Mechanical Fixing

Room should be left around the module for all the connections and cables, allowing for a suitable bending radius on each lead. Power wiring should be suitably fused or protected with miniature circuit breakers (MCBs) external to the master station.

The master station may be mounted on a flat surface using the mounting brackets provided. Also, the extension brackets allow it to be mounted in a 19-inch rack. In either case it should be located in a way that permits easy access to the pushbuttons and easy viewing of the display panel(s).

Before mounting the master station, set the communications link

switches, as discussed in section 3.

1.2 Host Serial Communications Connections

The serial data connections are via the D-type connectors below each master station PS710 on the main chassis. They are labelled Port 1 and Port 2 on both the A and B (left and right) sides of the assembly. All the connectors are 9 way female and they may be set for RS-485 (2-wire) or RS-232 use. On hot standby systems they can be cross coupled to provide seamless communication when the systems change over. The pin-out connections are shown below.

 With RS-485 it is possible to arrange a multi-drop data highway for the serial communications,

whilst RS-232 must be single point communications.

1.3 Ethernet Communications Connections

Each Pakscan P3 CPU module (master station module) has 2 x RJ45 Ethernet connectors for the two host communication ports (accessed from below) marked Port 3 and Port 4. A third RJ45 connector is located on the front of each module. This is provided to allow a portable computer (laptop) to be connected for diagnostic and set up purposes. Standard Ethernet patch cables can be used with these connectors.

All Ethernet cables must be screened, and of good quality. Many screened Ethernet cables of low quality have questionable screening efficacy.

All Ethernet ports on the master station have LEDs to indicate communication. Green indicates 10M bit/s and orange indicates 100Mbit/s. Communication may be half duplex or full duplex.

1.4 Power Connector and Fuses

Each Pakscan P3 CPU module has its own internal power supply. A standard IEC connector is provided to allow the mains power (85 to 263V AC – 47 to 63 Hz) to be connected from below the module. The mains IEC socket also includes the two fuses for the system, which must only be replaced with the same and rating 250V 1A 5x20mm anti-surge fuses.

For the 24V DC version, a three pin removable screw terminal connector is provided. There is no internal fuse.

1.5 Alarm and Hardwired ESD Connector

There is a removable screw terminal connector in each Pakscan P3 CPU module for the connection of ESD hard-wired inputs and for connection to the internal alarm relay contacts, when required. On most systems these terminals will not be used; in which case a hard-wired link between pins 4 and 5 must be fitted, this is usually fitted by the factory.

Note the relay is shown in the ‘alarm active’ or ‘power removed’ position. The Alarm relay will activate if there are any alarm conditions in any field unit or the master station. This alarm will not prevent operation of the master station.

1.6 Current Loop Connections

A connector is located in the bottom of the key switch module on hot standby Pakscan 3 systems for the connection of the current loop to the field mounted actuators. On single P3 master stations the connector beneath the current loop module itself should be used.

1.7 P3W Coordinator Connections

A connector is located in the bottom of the (PS721) wireless option module to connect to the P3W coordinator (PS722). The connection between these should be made using a shielded network cable with 3 pairs of wires – each pair to be twisted. Suitable cable conforms to the specification for RS-422 networks. This cable can be up to 200m long so that the P3W coordinator may be mounted, for example, on the roof of the building containing the master station.

The Communications cable and appropriate glands for the P3W coordinator will need to be sourced locally, according to site requirements. Connect the Communications cable as shown below, noting that the connections are NOT all one to one.

1.8 P3W Repeater and P3W WMA AC Power Connections

The P3W Repeater AC and the P3W WMA AC will contain a power module for the appropriate power supply requested by the user. The power module is mounted the base half of the module with the wireless module in the other half, the modules will be connected together by an interconnecting loom, connected to SK1 on the power module and SK3A on the wireless module. The mains AC connections are made to the power module connections L1, L2 and L3, shown in the Figure below. The mains cable will need to be terminated in 4 mm ring crimps.

SK1, a flying lead, will be fitted by the factory to the appropriate tapping for the power supply that the customer has indicated will be used. Fitting to the posts labelled W, X, Y and Z selects the correct voltage. This should be checked for correct fitment before power is applied.

A switch or circuit breaker must be included in the wiring installations. The switch or circuit breaker must be mounted as close to the module as possible and shall be marked to indicate that it is the disconnect device for that particular module. The Power cable and appropriate glands for the P3W coordinator will need to be sourced locally, according to site requirements. Power supply: 3 Phase up to nominal 690V, 50 or 60Hz or Single Phase up to nominal 230V, 50 or 60 Hz. Check that the supply voltage agrees with that stated on the nameplate.

Power should only be applied with the module fully assembled i.e. the base

and the cover connected together with the bolts supplied.

Cable glands used must be appropriate to the classification of the area.

Conduit seals must be installed at the enclosure.

Fig 14: Power module for P3W Repeater-AC and P3W WMA-AC.

SK2 is the Modbus connection. U1 is the cable screen clamp. SK7 is the loom for the Wireless pcb. FS1 is a 250 mA S500 fuse. FS2 is a 100mA TDC11 fuse. The wire attached to SK11 should be attached by one of the pcb mounting screws to the casing.

1.9 P3W Repeater and P3W WMA 24VDC Connections

The P3W WMA DC may be powered from the Modbus device to which it is connected, assuming the device has the appropriate DC supply available. Under this circumstance the interconnection cable between the device and the P3W WMA-DC should contain 2 shielded pairs, one for power supply and one for the communication signal. In this case, the distance between the Modbus device and the P3W WMA-DC should not exceed 10 meters.

The P3W repeater DC may also be powered from an external DC supply in the same way. Connect the power cable as shown below, the connector labelled SK3A is used on the P3W WMA-DC

and P3W repeater-DC. The power supply should be nominally 24volts (range 9-35volts, suggested power supply current

capabilities – 200mA)

1.10 P3W WMA Modbus Connections

The P3W WMA connects to a Modbus RTU device enabling a Modbus host to connect through the Pakscan wireless system to the Modbus device. The connection between the Modbus device and the P3W WMA should be made using a shielded network cable with 1 twisted pair of wires. Suitable cable conforms to the specification for RS-485 networks. This cable length will depend on the baud rate chosen for communications.

The Communications cable and appropriate glands for the P3W coordinator will need to be sourced locally, according to site requirements. Connect the Communications cable as shown below, the connector labelled SK3A is used on the P3W WMA.

1.11 Setting up the P3W Repeater and P3W WMA

The P3W Repeater requires the PAN ID (Personal Area Network Identification number) and RF Channel to be set up for the network to which it is attached. The P3W WMA also requires these parameters and its Modbus communication parameters to be set up. This is achieved using the Modbus interface that is available on both modules.

The Modbus physical connections are detailed in the previous section ‘P3W WMA (Wireless Modbus Adapter) Modbus Connections’. For the purpose of configuration, these connections can be temporary, for example, it may be more convenient to make the configuration changes in a workshop before installation on site. For both devices it is likely that configuration is only required once, therefore after installation there should be no need to access the Modbus connections again on the P3W repeater.

During configuration in a workshop environment, the 2 halves of the module can be separated, such that the Wireless module is disconnected from its power supply module. The wireless module can then be powered, separately, using a 24VDC source as described in the previous section ‘P3W WMA (Wireless Modbus Adapter) 24VDC Connections’.

For making configuration changes to the P3W Repeater or P3W WMA, there is a fixed Configuration Modbus address of 248.

The P3W Repeater, requires the PAN ID and RF Channel to be set up, and if there are multiple P3W repeaters the Modbus slave address must be set up such that all P3W repeaters are unique and can appear as separate nodes on the wireless network.

The P3W WMA requires the Modbus communication parameters (baud rate and parity) to be set up, as appropriate for communicating to the Modbus slave device it is to be connected to. The Modbus slave device address is not required to be set up within the P3W WMA, as it will automatically scan for attached devices using the baud rate and parity set. Up to 10 slave Modbus devices can be connected, each device will require a unique Modbus address, within the range 201 to 247. The address must be unique for the host device to be able to access it. Within the master station configuration pages, the Modbus addresses used for the devices fitted to the P3W WMAs are required to be selected. See section 7.5.17 master station configuration.

Changes to RF communication parameters will take place immediately. Changes to Modbus communication parameters will take effect after a power cycle.

1.12 Front Panel LEDs

There are four Light Emitting Diodes (LEDs) on the front panel of the CPU module, in the bottom righthand corner. These are fitted to show if a unit is powered-up, which unit is in Primary or Standby mode and whether there are any errors or alarms.

On power-up, there is a sequence of colour changes and flashes from the LEDs, which take almost a minute to complete and confirms that all parts of the system are operating correctly: The Status LED sequence is: off > amber > flashing green > steady green. The Pri/Stdby LED sequence is: off > green > off > amber > steady green (amber for standby). The Power LED sequence is: off > amber > green > green > steady green. The Alarm LED sequence is: off > red > off > red > off.

The Status LED will show steady red if communications with the host is lost over Ethernet, or there is a communications error between the master station and a field unit. The LED shows flashing green only during the power-up sequence. The LED shows steady green to confirm that all applications are running after power-up is completed.

The Pri/Stdby LED will show steady green if it is a single unit or if it is the Primary unit of a hot standby pair. The LED will show steady amber if it is the Standby unit in a hot standby pair.

The Power LED is off when there is no power and steady green when power is present. It only shows amber during the power-up sequence.

The Alarm LED will show steady red if there are any alarm conditions in any field unit or the master station. This alarm will not prevent operation of the master station.

2. THE FIELD CURRENT LOOP NETWORK

The Pakscan current loop field network must be correctly cabled and connected to the master station. The values of the field loop resistance and capacitance must be known to determine the loop speed that can be used. If these are not known then the LOWEST loop speed must be set in each actuator and the master station to ensure good field network connectivity.

2.1 Loop Checks

The most common errors in installing the system occur on the field wiring.

Loop Continuity

With all the field units connected, but none of them powered up, check the continuity of the 2 cores of the Pakscan loop cable. Measure and record the resistance of each core. These measurements will be useful as they can be compared with future measurements to determine if cable resistance has changed significantly or not, this may help identify a cable fault. Cable resistance (R) is the sum of the resistance of both cores.

Screen Continuity

Screen continuity must be continuous between each end of the loop. Ensure the screen is either connected to a signal earth bar at only one point or to terminals on the loop driver plug; pin 3 connects directly to the enclosure earth and pin 6 connects to the enclosure earth via an internal capacitor, preventing an earth loop. Both screens must be connected to the terminals provided on the loop driver, so as to ensure the product meets the European Directive on EMC.

Cable Capacitance

The capacitance (C) between the cores of the cable is critical to system performance. Too high a capacitance for the selected loop baud rate will result in poor communications, or even communication failure. If a suitable meter is available, measure and record the capacitance between the cable cores.

Maximum Loop Speed

The cable resistance must not exceed 500 Ohms (250 Ohms per core) and the total capacitance must not exceed the maximum value for each communication speed. In addition to cable capacitance, each field unit adds a small amount of capacitance to the loop which must also be considered when determining maximum loop speed. Use the measured resistance and capacitance values from the above tests to determine which loop speed should be used.

Test Equipment

A good quality multimeter with capacitance test facility is adequate for testing loop resistance and capacitance. Under no circumstances should any high voltage test equipment be used such as insulation Megger testers when any part of the cable loop is connected to either the master station or actuators. The high test voltages generated by such equipment may damage the Pakscan components.

2.2 Connecting Up

Once the checks are complete, connect the Loop Cables to the PS730 Key switch module on a hot standby system or the PS720 Current Loop module on a single system. The Pakscan loop should look like the figure below. Check the loop wiring complies with this drawing and then proceed to Section 8.1 for commissioning instructions.

Note: If there is no hard-wired ESD requirement a shorting link must be fitted across pins 4 and 5 on both side A and side B of the PS710 modules.

3. THE FIELD WIRELESS NETWORK

A Pakscan wireless network will contain a master station with a PS721 module fitted to its back plane (2 for hot standby). Each of these will connect to a PS722 P3W coordinator module. The P3W coordinator module is the device that controls and organises the wireless network. For an actuator to be connected on the network it must have a wireless actuator module. The IQ and IQT range of actuators fully integrate into the wireless system. Other devices can be integrated into the system using a Wireless to Modbus adaptor (P3W WMA). The P3W WMA can be attached to any device that has a Modbus interface on it. The host then uses the master station and the wireless network as a transport layer only to send Modbus messages that are directed to a Modbus device.

A network may also require a number of P3W repeaters to overcome wireless dead spots or to ensure a redundant path to all devices.

Fig 23: A typical P3 wireless network Up to 60 devices can be connected in a wireless network. The distances between each node in the

network is recommended to be no more than: Indoors: 30 metres Outside: 100 metres

In practice, it has been found that these distances can be extended, but a site survey is required to confirm this. Each device is able to route messages onto the next device. By this method, the range

of the network is increased. It is recommended to have no more than 7 ‘hops’ from the master station

to the final device. A ‘hop’ is where a message routes through a wireless device to get to the

destination device.

3.1 Wireless Site Survey

The first step in setting up a wireless network will be a Wireless Site Survey, which would be performed by Rotork Personnel. This will establish the suitability of the site for a wireless network. The survey will establish the levels of background wireless signals within the spectrum of the 2.4 GHz band used for the P3 wireless network and also the potential strength of the wireless signals between the actuator and P3W coordinator locations. This will aid in positioning the P3W coordinator and in deciding upon the need for P3W repeaters.

As a result of the survey, one or more channels within the band will be found to be suitable for the network. All devices on the network will be shipped with a default channel set.

3.2 Wireless Specification

Network Based on: IEEE 802.15.4, DSSS (Direct Sequence Spread Spectrum). Maximum Wireless devices: 60. Frequency: 2.4GHz band. Operating Range: 30m indoors, 100m outside. Network Structure: Mesh. Channels available: 16. (Currently 13 are useable). Security: AES and anti-spoofing. Power: 10mW default, potential for 100mW if the location allows.

3.3 Connecting Up

The IQ and IQT actuators fitted with a wireless module will only require mains power connections and the appropriate glands for the environment to be connected to them. Where a P3W WMA is supplied, power is required to be provided by the user and the user must also provide the necessary cable and glands between the WMA and the device to which it is attached. A P3W repeater also only requires a power cable and glands supplied by the user. The power required for the P3W Repeater and P3W WMA will be indicated on the serial label.

Figure on the next page shows the master station block diagram. The site survey will have indicated the appropriate position to locate the P3W coordinator(s) and any

P3W repeaters. Once all the equipment is in place, the user can then proceed to Section 8.2 for commissioning instructions.

4. CONFIGURING SERIAL COMMUNICATIONS

The Pakscan 3 CPU module has two serial ports. Each of these is configurable for RS-232 or RS-485. Most hot standby systems will probably require two RS-485 connections in a seamless redundant configuration. Single systems may use RS-232 or RS-485.

4.1 Setting Port 1 and 2 for RS-232 or RS-485

The chassis has DIP switches behind the PS710 CPU module for setting the type of serial port that is presented at the port connectors.

Fig 25: Pakscan P3 Chassis, CPU and Key Switch modules removed

The switches on the backplane behind the PS710 CPU Module are used to set Port 1 and Port 2 parameters.

To access the switches, you will need to remove the modules shown above from the backplane. To do this, power-off the master station completely from any power sources, either mains or DC. Then

unscrew the hex head bolt from the top of the module using the 2mm ball driver tool supplied with the master station. Once the screw is removed, or loosened sufficiently, the module may be carefully pulled forward at the top until the lower claws of the module can be unhooked from the slots in the backplane.

If any plugs are left in the power sockets or serial sockets, these may prevent you from tipping the module forward sufficiently to unhook it from the backplane.

Replacement of the module is the opposite of removal, being careful to align the module and backplane connectors.

Port Function

Two DIP switches allow each port to be selected between RS232 and RS-485. For RS-485 slide the appropriate Port switches to the right, for RS-232 they should be on the left.

Each of the two ports may be set independently.

Fig 26: Port Function Switches shown in RS-232 position

RS-485 Termination Resistors

Two DIP switches are used to connect end-of-line termination and biasing resistors to the RS-485 highway. All RS-485 network highways must be terminated at both ends of the highway, in this case, at the host controller and at the master station. Only RS-485 highways need termination and biasing resistors. If a CPU port is configured for RS-232, it must never be terminated. Each port can be terminated independently.

Each CPU module serial port sits on an independent highway and should be terminated independently. So, if ports 1 & 2 on a CPU module are both being used for redundant RS-485 communications to a Host controller, then each port may need to be terminated and biased.

However, where more than one CPU Module sits on the same RS-485 highway, then only the one furthest from the host controller needs the biasing and termination resistors to be enabled.

Cross Connection switches

The cross connection switches, found on the backplane behind the PS710 CPU Module, are used to cross connect the serial RS-485 connections. They are only applicable for a hot standby system and should ONLY be set as cross connected for a port that has been selected as RS-485.

Fig 28: Cross connection switch settings on the backplane behind the Switch Module The switches are shown in the Factory Default positions (Hot Standby). Port 1 is set to Cross-Connected for RS-485 Serial communications. Port 2 is set to Not Cross-

Connected for RS-232 Serial Communications. The feedback switch positions must reflect the Cross-Connection settings for Port 1 and Port 2.

These switches are used, by the master station CPU, to indicate to the user (via the HMI or web pages) the position of the cross-connect switches.

Communications between the Host and the master stations uses the Modbus protocol. Because the Master A is cross-connected to Master B, they both share the same Modbus address. The standby action must then be set to passive. Thus, the host can have two-way communications with the Primary (Main ) module and the Standby module will only listen to the messages.

With RS-232, communications between the Host and Hot Standby master station must be point-topoint. Multi-drop connection is not allowed, so separate cables must be run from the Host to each side of the master station. Also, the Cross-Connect switch must be set to Not Cross-Connect. The standby action must be set to active, so that the Host has full communications with Master A and Master B. Note: only actuator commands sent to the Primary CPU Module will be actioned.

5. CONFIGURING ETHERNET COMMUNICATIONS

Pakscan 3 master stations come complete with two Ethernet ports for connection to host systems. A third Ethernet port is also available for connection to a computer for configuration purposes. The master station is ready to use with Ethernet and Modbus TCP protocol for the host to access data and control the actuators on the field network. The IP address is factory set to the default value and can be changed during set up of the master station.

The Pakscan master station defaults to the same IP address on both ports, and can use the same address on the A and B master stations. It is possible to change the IP address on either master station, but ports 3 and 4 of each CPU Module always have the same address.

Ethernet comms between Hosts and master station are made using Port 3 or Port 4. The CrossConnect switches can be in either position, or set appropriately for any additional serial comms. In this case, with two Hosts, Standby must be set to Active. The IP address of Master A and Master B can be set to be the same or different, with Standby Active.

Fig 31: Hot Standby, Dual Redundant Ethernet Communications

For full Ethernet communications redundancy, use two Hosts and two managed Ethernet switches. Managed Ethernet switches with rapid spanning tree protocol are required. This type of switch is able to prevent Ethernet Storms, where messages are re-circulated continuously.

Ethernet communications between Hosts and master station are made using Port 3 and Port 4. In this case, with two Hosts, Standby must be set to Passive. The IP addresses of Master A and Master B can be set to be the same with Standby Passive, or different, with Standby Active.

The Pakscan P3 master station defaults to the same IP address on all ports. It is possible to change the IP address for Master A and Master B independently, but all ports for each master will have the same address. In a hot standby system, if the Copy IP Settings option is selected, both sides of the master station will have the same IP address.

5.1 Default Ethernet Settings

The default Ethernet parameters set in each Pakscan 3 CPU Module are given below:

DHCP

Static

Default IP address

200 1 1

Default Subnet mask

255

255 0 Standby Action

Passive

Changes to the IP address, Subnet Mask or clock settings will cause a re-boot of the CPU module.

The master station uses the 192.168.1 subnet internally, therefore if it is required to set the external IP address of the master station to a value within this range the internal address will need to be modified. Contact your local technical support team for details.

5.2 Ethernet Security

When connecting the master station to an Ethernet network, care should be taken to consider security of the master station.

There are a number of Ethernet services available in the master station and, where appropriate, the user should ensure that the Ethernet infrastructure is able to protect the master station from unwanted access to a service.

Transmission Control Protocol (TCP) and Internet Protocol (IP) are the core protocols utilised in Local Area Networks (LANs) and computer networking. Within these networks a ‘port’ is an endpoint to a logical connection – not to be confused with the physical port!

The port number in this case refers to the type of port. For example, port 80 is used for HTTP web page traffic.

The ports that are available at the master station are:

Port description

Port number

HTTP

HTTPS

443

Modbus/TCP

502, 50003, 50004, 50005, 50006, 50007, 50008 and 50009

Ethernet products, like routers, can prevent other Ethernet equipment on the same LAN from accessing certain services in the master station. If web page access were not required, the most secure set up would be to prevent all but Modbus traffic entering the master station.

Use the arrow keys ( or ) to change the value shown until the desired figure appears, then press ENTER and the new value will be set. The arrow keys can be used to navigate to other settings, and the NEXT button goes to the Loop Test screen and Loop Reset function.

 Set the loop performance parameters in accordance with the data recorded earlier. Make sure

the loop speed is compatible with the setting for the loop capacitance.

 Set the highest field unit address parameter equal to the actual highest address.  Doubling can be set to ‘On’ if the loop performance is not fast enough. It has the effect of

halving the time to collect data from the field units. This feature will only operate if the loop is functioning correctly with “loopbacks off”.

 IQ DV Convert should be set to ‘On’ if analogue position control is being used on the IQ / IQT

actuators on the network.

 Data Retain set to ‘Off’ clears all the field unit data if communication is lost. Some host

systems want the data to be retained, in which case set the parameter to ‘On’. Once the parameters are all set, leave this part of the setting menu to ensure the new values are loaded. Use the BACK button to return to the Host Settings page, and then ENTER to select the Host Settings menu.

Make alterations to the host protocol settings and Alarm linkage, if required, in a similar manner to altering the loop performance parameters described earlier. The PIN will need to be entered if no keys are operated for approximately 5 minutes from the last PIN entry. Where the two serial ports are being used by the same host system it is advisable to ‘Link’ the alarms so that both ports always report exactly the same alarm data.

 Set the Num of FCU to the actual number of Field units in the network. The field units will be

numbered from the lowest FCU address contiguously for the Number for field units fitted.

 Set the PAN ID to a value different from the default. This should be noted as this needs to be

set in all the individual field units.

 Data Retain set to ‘Off’ clears all the field unit data if communication is lost. Some host

systems want the data to be retained, in which case set the parameter to ‘On’.

 Set the AES key to something different from the default. This should be noted as this needs

to be set in all the individual field units.

 The most suitable channel for the system will have been selected during the site survey. This

setting should be set to that value.

 Set the number of P3W repeaters used in the system – P3W repeaters may be required in the

system to ensure redundancy or for improved communications. The network can be reset from the second page. This will need to be done if network changes have

been made and these are required to be uploaded to all field units. Note that changes to network parameters will only be loaded to those devices currently communicating on the network.

When the settings are as required, use the BACK key to return to the top Settings menu.

The port type is determined by the DIP switch settings on the main chassis behind the PS710 CPU module and the setting is reflected in the message on the screen. If the port is set to RS-485 and cross connected, the description changes to show these settings. This is particularly useful when determining the settings already in place. Select the option to be changed by using the arrow keys ( or ), then ENTER (the PIN screen may appear before a change can be made). Once the PIN is entered, the value of the parameter can be altered by the arrow keys ( or ). The speed can be varied from 2400 to 115,200 and the parity may be Odd, Even, Zero or None. Once the value is as required, press ENTER to set the value.

When the parameters are all as required, press BACK to return to the Host Settings screen, then select the Modbus Address using the arrow keys ( or ) and press ENTER.

 The Pakscan 3 Modbus address is for accessing the Wireless database.  The Pakscan 2 Modbus address is for accessing the Wired (current loop) database.  The Pakscan 2 and Pakscan 3 Modbus addresses MUST NOT be the same value.

The Modbus address for the communication to the actuators on the Pakscan 2 current loop (via the module in option 2 slot) is altered in the lower window. It is recommended that this is altered to a value other than the generic Modbus default address of 247 and the master Station defaults to ensure that any new stations introduced do not conflict with this address.

The address is changed by first selecting it with the arrow keys, then pressing ENTER (if the PIN requires entry the prompt page then appears). Use the arrow keys to change the number to the new value, and then press ENTER once more. The new address becomes active once the screen has been changed to a new one.

The Pakscan 3 wireless Modbus address is modified in the same way.

Once the settings are as required, use the BACK key to return to the top Settings menu.

6.6 The Other Settings

There are menus for setting all the parameters of the system. These are more fully explained in the system manual and, in general, the default settings will allow most systems to operate with reasonable success.

6.6.1 Security

Security is used for setting the PIN number to be used, plus the actions permitted from the keypad and the serial ports via the Interlocks. The Security setting default requires a PIN for adjusting the settings for system performance, but not for issuing actuator commands.

Interlocking controls the serial communications that are permitted to operate the actuators. The default grants permission to all the serial ports and the Ethernet ports, but prevents the web page facility from moving the valves.

 The default PIN = 0000.

6.6.2 ESD

The default condition is to disable all the possible Emergency Shut Down routes. ESD can be enabled from the serial ports, Ethernet ports, Web page, hard-wired input or keypad on an individual actuator selection basis. If this ESD function is not required, ensure that a shorting link is fitted across pins 4 and 5 of the PS710 CPU module connector.

6.6.3 Date and Time

The date and time, plus the use of an NTP server are set from this menu. The time stamp is used for the logging facility.

6.6.4 Master Station Parameters

The master station parameters include the Tag for the master station and the setting for data transferred between the two CPU modules on a hot standby system along with several other parameters. Most of the default settings are suitable on most systems, though there is one particular set of parameters that must be correctly set in the case of hot standby systems.

The Serial Ports should appear as Passive if the Cross Connect DIP switch is set to ‘cross connect’. If the port is set to RS-485 highway and is being used on a multi-drop highway it must be set to passive. If it is not shown correctly it probably means the DIP switch is incorrectly set.

Remember, the default setting is Standby Active.

7. Internal Web pages

Issue 06/15 Publication PUB059-002-00 51 of 136

7. INTERNAL WEB PAGES

The master station includes a set of web pages that may be remotely accessed via Ethernet. They can be used for setting up the system, examining the system for any faults or alarms and also for controlling the actuators on the network (provided the Interlock permission is set to allow this feature).

If the master station is connected to an Ethernet Network it will act as a web server and any computer within that network can connect to the master station. The master station can also be configured and the field network set up by using these web pages. The host system or computer connected via the Ethernet Network or directly will need a web browser such as Internet Explorer to access the master station web pages.

7.1 Making an Internet / Intranet Connection

Connect the master station to an Ethernet host as described in section 5, or connect via a suitable router to the internet / intranet. A computer can be connected directly to the master station using the configuration port.

Start the browser and enter the IP address of the master station. The default address is 10.200.1.1, so the address is http://10.200.1.1. The browser will then access the master station and bring up the opening page of the master station. In order to log in as a verified user, enter a user name of admin and a password of admin. (The default password should be altered as soon as convenient to prevent unauthorised access to the system.)

Default IP address

7.2 Connecting a Computer Directly to the Master Station

The simplest direct connection to the master station is by using the Ethernet port on the front of the CPU module. A standard Ethernet patch cable or crossover cable can be used to link the two directly. A permanent connection can also be made directly to one of the underside connectors (port 3 or 4). In order to establish a connection it is probably necessary to adjust the settings of the computer’s Internet connection.

Network Diagnostics

No. Of Devices : This is the number of field units that are expected to be located on the On Network network. It is the highest address that the network will scan up to when

locating field units. All field units need to be consecutively addressed, and

there should be no gaps in the addresses.

No. Of FCUs : This is the total number of field units located on the network. If all the field Found units are powered on and connected, then the number will equal the No. Of

Devices On The Network above.

Configuration : This field shows any fault that exists on the network cabling and the stages Status passed through as network configuration takes place.

During configuration the following sequence can be displayed -

1. Wait for Loopbacks 1 (first wait for loopbacks to come on)

2. Find FCUs on Port A (finding FCUs on port A)

3. Test Loop (testing for complete loop)

4. Find FCUs on Port B (finding FCUs on port B)

5. Wait for Loopbacks 2 (second wait for loopbacks to come on)

6. Loopbacks off on A (removing loopbacks from port A)

7. Loopbacks off on B (removing loopbacks from port B) (The normal sequence for a fault-free loop would be 1, 2 and 3. A

sequence for a break in the loop, anywhere except at port A or port B, would be 1 to 7. Some of the phases may be very quick, particularly at higher baud rates, and so may not be seen on the browser display.

Whilst the configuration is taking place, the master station web page shows ‘Loopback in Progress’ and a blue light on the Option module.

If the configuration process detects a fault on the loop and switches on the loopback circuits of two field units, the master station web page shows ‘Loopback in Use’ and illuminates the yellow light.

Last Network : The loop can be reconfigured for a number of reasons and this field will Reset Initiated show the cause of the last reset/reconfigure that occurred. By The possible reasons are:

Power on Reset - loop configured because the master station

powered up.

Fault Found - fault detected on the loop whilst it was running

without loopbacks present.

Fault Found A - fault detected on the A side of broken loop whilst

running with loopbacks on.

Fault Found B - fault detected on the B side of broken loop whilst

running with loopbacks on.

Reset Command - loop Reconfigure command entered from keypad

or serial port.

Return wire fault - fault detected in the return current path whilst the

loop was running at double speed.

Doubling failed - fault detected after loop assumed double speed.

Network Fault : This field shows the type of fault detected that caused the loopback to Type occur, or an addressing fault on the field units. The types are:

Zero Address - a field unit has been found with an address of zero. Address too High xx - a field unit has been found with an address higher than that set up within the master station; xx is the address. Same Address xx - two field units found with the same address; xx is the address. Loop Open Circuit - an open-circuit fault found on the loop. Loop Short Circuit - a short-circuit fault found on the loop.

If two field units are found with the same address, or there is an address outside the range of addresses expected (as set by No. of Devices on Network), the network will continue to operate and miss out the faulty field units.

Loop Baud Rate : Shows the current speed selected. The speed can be 110, 300, 600, 1200,

or 2400 baud.

No. Of FCUs : This is the total number of field units connected to the option module Port A On Side A and communicating via Port A.

No. Of FCUs : This is the total number of field units connected to the option module Port B On Side B and communicating via Port B. Port B is only used if there is a loopback

present on the network.

Controls - Available to all user levels

Reset network : Causes the option module to reconfigure the 2-wire network. This should

be used after a loop fault has been corrected.

Network Map

The map shows the order in which the field units have been identified and found by the option module during the last loop reconfiguration process (reset). Each time the loop is reconfigured the map is regenerated and repopulated. Any field unit that is not powered-up at the time of reconfiguration will be absent from the map.

Position : The position in the loop. Number 1 is nearest to Port A. Address : The address of the field unit. Failures : Shows a count of communication errors with the field unit. The count has a

range of 0 to 255, after which it rolls around to zero and it increments for

every communication error. The system will only announce a ‘Comms failure’ when 3 successive tries have failed to locate the field unit. This

counter therefore reflects the communications condition and can be used as an indicator of the health of the field unit to assess the probability of failure in the future.

Wireless repeater nodes found

This is the total number of P3W repeater nodes found on the network. If all the P3W repeater nodes are powered on and able to communicate, the number will equal the number expected on the network.

Configuration Status

During configuration of the wireless network the network goes through various stages as indicated below. Some of the stages can be quite quick and therefore may not be seen:

 Uninitialised.  Initialised / starting up.  Detecting field units.  Building map of field units.  Detecting field units complete.  Obtaining initial field unit data.  Field unit data collection complete.  Network Ready to run.  Master station updating RF parameters.

After a reset network command is sent from the web page, the normal sequence seen would be: Initialised / starting up, Detecting Complete, Obtaining initial Data, Data collection complete, Ready to run. ‘Ready to run’ is the normal state of a good network.

Last Network Reset Initialised By

This field indicates the cause of the last reset, this can either be due to a power cycle (value will be 00), as a result of receiving a reset network command, due to a parameter change causing the P3W coordinator to reset or due to a Radio communications parameter change.

Network Fault Type

This field indicates any faults on the network. Faults reported can be:

 P3W coordinator fault.  Insufficient wireless neighbours for the P3W coordinator or

the field units, the intention is always to have at least 2 neighbours.

 RF parameter change failed.  Duplicate field unit address detected.

The LQI is represented as a percentage value and is a good indication of signal quality and strength. A good signal would be in the range 93% to 100%. A reasonable signal would be in the range 61% to 92%; reasonable means that if environmental conditions deteriorate there is a greater potential for message retries and message failure.

It should be noted that rain, humidity and fog have a negligible effect on the wireless network. The greatest effect can be seen for heavy snow. By this, we mean snow that has settled on and around the antenna, i.e. 2 inches of snow packed around the antenna can cause a loss of about 10dBs.

Masterstation Configuration [General Settings]

Site Name

A text field in which a description of the site can be entered for identification purposes.

Tag Name

A text field in which a tag identifier for this particular master station on the site can be entered.

Option 1 and Option 2 Modbus Address

A numeric field for the address number. When addressing the P3 master station using a host, the user must use the appropriate Modbus address. It is possible to fit up to 2 network option modules to the P3 master station. Each option module will have its own Modbus address, therefore there are up to 2 Modbus addresses to set up, one for each option module fitted. In a system with only 1 option module fitted, only the address for the appropriate option module fitted is required to be set up.

The default value is 240 for a Pakscan 2 Loop option module and 200 for a Pakscan wireless option module. It is recommended that his is changed to avoid conflict with any new system added

Note for Pakscan 2 Loop module Modbus Addressing

In some cases when using Pakscan Generic Modbus protocol settings, the master station will respond to more than one address; and the setting here is the Base address. There is more information on the base address and offset addresses in the Pakscan Modbus Protocol document (PUB059-003 formerly S171E).

Monitoring wireless and Control wired

Only in a system where each actuator has a wired and a wireless Pakscan module fitted, should this be enabled. This feature will pair up the wired and wireless modules and enable them to be shown together in the FCU menu web page. The pairings will be:

 the first wired address with the first wireless address,  the second wired address with the second wireless address,

 ...... and so on.

Therefore in a system where the wireless addresses start at 61 (wired always start from 1) the pairings would be:

 Wired address 1 with wireless address 61  Wired address 2 with wireless address 62  Wired address 3 with wireless address 63

 ..... and so on.

The FCU menu will appear as below:

Hot Standby Module

Either ‘Enabled’ or ‘Disabled’. When there is a partner module acting as a standby unit this option should be set to ‘Enabled’ to allow exchange of data between the two modules.

ESD Settings

These five drop-down boxes can each be set to ‘Enable’ or ‘Disable’ the related Emergency Shut Down signal, depending on the particular site requirements. In general the settings should be ‘Disabled’ unless the particular Emergency Shut Down function is required. The action for each individual actuator has to be set locally on the actuator to either close, open or stay put (no movement on receipt of the ESD signal), as required for each valve; refer to individual actuator manuals.

Command Settings

These five drop-down boxes can each be set to ‘Enable’ or ‘Disable’ the host system commands to the actuators and field units from the indicated source of the signal. For example, commands over the Ethernet connection can be disabled, whilst those from Serial Port 1 can be enabled. Ethernet commands are those sent via the Ethernet ports from the host system using Modbus TCP. Commands on the individual field unit web pages can also be disabled. Serial Port 1 and Serial Port 2 are the RS-232/RS-485 Modbus RTU ports, which are commonly used for control and monitoring. The Keypad is the control source on the front panel of the CPU module.

Copy Options

These four drop-down boxes can each be set to ‘Enable’ or ‘Disable’ the copying of information between the A side and B side CPU and Option modules in a hot standby system. They do not appear in a single module system.

Settings - Enable to copy all the settings, except those listed below, between the units.

Address - Enable to copy the Modbus addresses of the CPU (P3 option) and Pakscan Loop option module between the units.

Tag - Enable to copy the Site name and system Tag name between the units.

IP - Enable to copy the IP address and Ethernet settings between the units

Display Language

This drop-down box contains the options enabling the system language to be chosen. The options are English, Spanish (Espanol), French (Francais), German (Deutsch), Italian (Italiano) and Hungarian.

Security Settings

A text box is provided in which the system PIN can be entered, and a drop-down box provides the options for access permission when using the CPU keypad and screen.

Note that the ‘Command Settings’ above can be used to prevent keypad commands under all circumstances, but when the keypad is enabled the security settings below will apply.

PIN - The Password number is a variable between 0 and 9999. When a number is entered, it indicates that the PIN must be used for settings or commands to be allowed from the CPU keypad in accordance with the associated drop-down box setting.

Security - The drop-down box contains the options for selecting the protection afforded against inappropriate actions when using the CPU keypad.

None : All settings and control commands accessible via the keypad without protection by a PIN.

Set up : Control commands accessible via the keypad without a PIN, but all setting changes via the keypad require the PIN to be entered first.

Set up and Control : Any control command action or setting changes via the keypad require the PIN to be entered.

Locked : No keypad access permitted for any control commands or setting changes whilst there is host activity on any of the serial or Ethernet data links. [If all serial and Ethernet communication links are inactive for 5 seconds then keypad commands can be entered provided the PIN is entered (as with the Set up and Control level)].

Software Version

The version of software fitted to the CPU module. In hot standby systems the modules in both the A and B side should have the same version of software.

Country Code

This setting relates to the wireless option only. Whilst the frequency band over which the wireless communicates is a globally available band, there are frequencies within this band that certain countries do not allow. This parameter is set up during the first 5 times that the master station is powered up or by using the HMI menu A3F. This setting will ensure that that the channels made available for selection within the wireless option module are only those legally available within that particular country.

Number of Channels

This value is derived from the actual hardware of the CPU and indicates the maximum number of actuators or field units that can be connected to this system. The field units can be split between the option modules fitted.

FCU distribution between Option Slots

Using the slider bar the user is able to select the number of field units connected to each option module fitted in batches of 60. Simply select and drag the bar to the appropriate setting with the mouse, the text above the bar will indicate what has been selected.

The bar will only allow selection up to the maximum number of field units available on the master station in question.

This bar only selects the number of field units allocated to the two option slots and not the address range of the field units on the option slot network. The Pakscan 2 loop actuators will always start at address

1. In the example shown on the next page, where there are 180 devices on the Pakscan 2 loop module, the addresses 1 to 180 will be for the Pakscan 2 loop units. The starting address for the wireless devices is set up in the wireless configuration section and this would logically (but not necessarily) be set to 181. This would mean that the addresses for the 60 wireless devices can range between 181 and 240.

Masterstation Configuration [Pakscan 2 Loop]

The Pakscan 2 Loop option module controls the actuators and field units over a 2-wire cable wired in a ring or loop, visiting each actuator in turn. The data signal is a modulated 20 mA current and the system includes automatic cable failure protection and detection.

Fig 74: Master station configuration web page: Pakscan 2 Loop

Software Version : The version of software fitted to the Pakscan 2 Loop option module. In hot

standby systems the modules on both the A and B side should have the

same version of software. Highest FCU : This text box contains the setting for the highest address used for an

actuator (or field unit) on the 2-wire loop. The Pakscan 2 Loop module polls

all field units from address 1 up to this highest address. The loop scan time

is minimised by restricting the polling to only those field units that should be

present and scanning up to the highest address. All the addresses in the

selected range should be used and gaps in the address range should be

avoided. Gaps or unused addresses cause the system to run more slowly

as the unused addresses are still checked. In addition, unused addresses

will generate a communication failure alarm. Loop Speed : This shows the current loop scanning speed (loop baud rate) and the drop-

down box allows a desired loop speed to be selected. The choices are

2400, 1200, 600, 300 and 110 baud. When a new speed is entered it will

take effect as soon as the values are saved. The setting applies to the

Pakscan 2 Loop option module only and the actuators must be changed

individually.

Issue 06/15 Publication PUB059-002-00 99 of 136

New Loop Speed : The drop-down box allows a new scanning speed (loop baud rate) to be

selected for the field units in the actuators. The new speed will be adopted

next time the loop is reconfigured. A change here should be mirrored by a

change in the loop speed setting above. It is possible to select rates in the

range one step up or two steps down from the current speed. If the loop communication is not stable, it is often necessary to reduce the

speed to improve reliability. If the field units are all in communication with

the master station, this facility to globally change the speed of all the field

units can be used to assist in improving the reliability. Loop Speed : On a stable loop it is possible to halve the loop scan time by doubling the

Doubling data speed using this setting. Care is needed to ensure that the loop

continues to be stable, since the use of this feature slightly reduces the

system’s capability to reject interference from pumps and motors. Retain Data on : Normally the database information about an actuator is cleared to zeros if

Loss of communication with the actuator is lost. This ensures that the false valve Communication position information is not transmitted to the host system during the loss of

communication. A single ‘Comms Fail’ data bit is set. This system setting

allows the data to be kept at the last value received from the actuator. Note

that the data is retained indefinitely and does not necessarily reflect the

true actuator status. DV Convert : This option can be used to ensure that 100% and 0% Desired Value

outputs to the IQ, IQT, Skil and EH actuators are transformed into actions

to make the actuator run to the fully open (100%) and fully closed (0%)

positions. The message is converted from a DV command to an Open or

Close command. This is useful for positioning actuators, where it is

possible that the valve will not fully shut or open when moved by only a

small amount. When used for tight shut-off valves, with analogue position

control only, the setting should be ON; the default is OFF.

If limited range positioning is selected, only enable DV Convert if you wish

the valve to travel to the fully open and fully closed positions. Host Port 1 : The drop-down box allows the database organisation use on this port to

Database be selected. The choices are Generic Modbus, Honeywell EPLCG Selection Modbus, Yokogawa Modbus and Honeywell SI Modbus.

Host Port 2 : The drop-down box allows the database organisation used on this port to Database be selected. The choices are the same as for Host Port 1. Selection

Ethernet : The drop-down box allows the database organisation use on the Ethernet Database ports to be selected. The choices are the same as for Host Port 1. Selection

Port Alarms : This drop-down box allows port alarm handling to be configured. Alarms

can either operate completely independently (‘separate’) for each port, or

can be linked such that the same alarm information is always reported,

regardless of which port is used. Alarms must be read and accepted before they can clear and return to

normal. If configured as separate, alarm reading and acceptance must be

done separately for each of the three ports. This ensures that the different

hosts see all the alarms. When the alarms are linked, accepting an alarm

on one port accepts the alarm on all the other ports as well.
