DV Convert should be set to ‘On’ if analogue position control is being used on the IQ, IQT, Skil
or EH 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’.
Select the desired host database type for each serial communications port and the Ethernet
ports for access to the actuators on the current loop. Refer to document PUB059-003
(formerly S171E) for database details. On Hot Standby systems link the alarms if both serial
ports go to the same DCS or PLC in a redundant communications configuration.
7.6.3 Masterstation Config - Pakscan 3 Wireless option
If a wireless module is fitted, the master station set up page is also used for setting up the Pakscan 3
Wireless Network. Set the network parameters in accordance with the network settings recommended
during the sire survey.
Set the PAN ID and AES key as chosen by the customer.
Set the channel number as determined by the site survey.
Set the lowest FCU address to the lowest address in the range of addresses possible for the
wireless module, avoiding overlap of addresses.
Set the number of FCU addresses to the number of field units to be connected to the network.
7.6.4 Host port settings
The physical parameters relating to the serial ports that may be altered are set by accessing the Host
Port page see section 7.5.18.
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. The description changes to reflect
the settings made. This is particularly useful when determining the settings already in place. In hot
standby systems the Cross Connected status of both the serial ports also depends on the settings of
the DIP switches behind the Key Switch module on the main chassis.
For each serial port, set the Baud rate and Parity as required. The speed may be varied
between 2400 and 115,200 baud, the parity may be Odd, Even, Zero or None.
On hot standby systems the Standby mode will normally be correct, when cross coupled, ports
should be Standby Passive.
On hot standby systems the Ethernet port needs to be set Standby Passive if both Ethernet
ports are on the same Ethernet highway to the DCS. If there are two routes to the host they
may be set Standby Active.
For security, IP Authentication should be set to the IP address of the Modbus TCP host(s). On a
private network it is unlikely that authentication will be required.
