Introduction
This manual relates to Pakscan 3 Master Stations fitted
with PS720 Current Loop modules and/or the PS721 and
PS722 Wireless modules
INTRODUCTION
Pakscan 3 is a complete field network control system from Rotork. With the addition of a wireless
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.
This manual provides a guide to setting up the Pakscan master station, the loop communications,
wireless communications, and the host connections for the most commonly found applications.
Most types of Rotork actuator 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 actuator integrate fully with the wireless network. Other
actuators or devices can be added to the system using a Wireless Modbus Adaptor (WMA).
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.

P3 - Pakscan Master Station Technical Manual
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 coordinator module (PS722).

1. Mounting and Connecting the Master Station
1.
MOUNTING AND CONNECTING THE MASTER STATION
Before mounting the master station, set the communications link
switches, as discussed in section 3.
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 Wireless 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, wireless 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).

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.
Fig 10:
Serial Communication connections
 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.
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

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.

1.7 Wireless Coordinator Connections
A connector is located in the bottom of the (PS721) wireless option module to connect to the Wireless
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 coordinator may be mounted, for example, on
the roof of the building containing the master station.
The Communications cable and appropriate glands for the Wireless 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 Wireless Repeater and WMA AC Power Connections
The Wireless Repeater and the WMA 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 SK6 and SK5, shown in the Figure below.
SK15, a flying lead, will be fitted 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.
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.
The Power cable and appropriate glands for the Wireless coordinator will need to be sourced locally,
according to site requirements.

1.9 WMA (Wireless Modbus Adapter) 24VDC Connections
The WMA 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 WMA should contain 2 shielded pairs, one for power supply and one for the
communication signal. The distance between the Modbus device and the WMA should not exceed 10
meters in this case. The power connection on the WMA are pins 7 (+ve) and 8 (0volts) of SK3A.
1.10 WMA (Wireless Modbus Adapter) Modbus Connections
The 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 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 Wireless coordinator will need to be
sourced locally, according to site requirements. Connect the Communications cable as shown below,

1.11 Setting up the Wireless Repeater and WMA
The Wireless 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 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 ‘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
Wireless 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 ‘WMA
(Wireless Modbus Adapter) 24VDC Connections’.
For making configuration changes to the Repeater or WMA, there is a fixed Modbus address of 248.
The Wireless Repeater, ONLY requires the PAN ID and RF Channel to be set up, whereas the WMA
also 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 WMA, as the WMA will automatically scan for
attached devices using the baud rate and parity set. Up to 10 slave Modbus devices can be
connected to the WMA, 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 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 and will apply to the Wireless Repeater
and WMA when configuring in the future as well as when the WMA communicates to its Modbus
device.

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.
Fig 18:
CPU LEDs (Light Emitting Diodes)
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 singe 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.

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 Megga 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.

3. The Field Wireless Network
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 Wireless coordinator module. The
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 (WMA). The 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 repeaters to overcome wireless dead spots or to ensure a
redundant path to all devices.
Fig 22:
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 coordinator locations. This will aid in positioning the coordinator and in deciding upon
the need for 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.

the appropriate glands for the environment to be connected to them. Where a 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 repeater also only requires a
power cable and glands supplied by the user. The power required for the Repeater and WMA will be
indicated on the serial label.
Figure 17 shows the master station block diagram.
The site survey will have indicated the appropriate position to locate the coordinator(s) and any
repeaters. Once all the equipment is in place, the user can then proceed to Section 8.2 for

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

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.
Port 2
Each of the two ports may be set independently.
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.

4. Configuring Serial Communications
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 27:
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 CrossConnected 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.

P3 - Pakscan Master Station Technical Manual
Typical Serial Host connections to the P3 master station and appropriate switch settings:
Hot Standby RS-485 communications
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.
Hot Standby RS-232 Communications
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.

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.
Where an Ethernet switch is used to connect a Host to the hot standby master station and the IP
address is set the same for Master A and B, then Standby must be set to Passive.

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. Configuring Ethernet Communications
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
Telnet
FTP
HTTP
HTTPS
Modbus/TCP
Port number
23
21
80
443
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.

SETTING UP THE MASTER STATION BY THE KEYPAD
The Pakscan 3 master station CPU module has a full colour display and 5 button input pad. All the
settings for the performance of the master station, the Option module fitted and the Field Network can
be made using these facilities. The keypad and screen also allows every connected actuator to be
interrogated and its status monitored. Finally, the actuators and valves can be moved using these
facilities.
Alternatively, a computer with an Internet browser facility can be used with the internal web server
pages. These pages allow the whole system to be set up and modified. In addition, they allow the
connected actuators to be viewed and controlled.

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.

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.)

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.

Ethernet control source, acting through the Ethernet ports.
The analyser will record up to 100 messages (requests and responses) on the data line between the
two points. It is especially useful for debugging a host control system to ensure that messages are
correctly formatted and that the required control or data points are being accessed. In particular, the
use of correct offsets in the Modbus protocol can be checked.

: This field shows any fault that exists on the network cabling and the stages
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

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

Network Fault
Type
: This field shows the type of fault detected that caused the loopback to
occur, or an addressing fault on the field units. The types are:
Zero Address
Address too High xx
Same Address xx
Loop Open Circuit
Loop Short Circuit
- a field unit has been found with an address
of zero.
- a field unit has been found with an address
higher than that set up within the master
station; xx is the address.
- two field units found with the same
address; xx is the address.
- an open-circuit fault found on the loop.
- 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,

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.

: 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.

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
