Pakscan IIE System Manual
Serial Host Communications (RS232 or RS485)
Where applicable, for communication to the host system what Protocol will be used, what Baud
rate is needed, what parity is needed? If there are two hosts this data is needed for both and
also if the alarms data bases should be separate or linked.
Ethernet Host Communications
Where applicable, what IP address is required for the master station? What is the Protocol that
is to be used? The settings for Port 1 and Port 2 will also vary depending on the connection
configuration of the Ethernet bridge module.

9.2 Serial Communication Ports

The master station may be configured for different functions on each of its two serial communication
ports. However the Modbus address of the master station relates to all the ports, they cannot differ.

The settings to make are in the Master Station Setup Menu as described in section 8.8. To reach the
required screens from the opening top menu screen, press '1' to select the master station side of the
menu structure. The next screen revealed shows the options for what to do next. Press '5' to select

Pressing '2' will scroll round the available protocols, select the required. Note that the Rotork PC
based plant control package, InVision, uses the Generic Modbus setting and Ethernet uses Generic
Modbus when the web browser is required.
Pressing '3' steps round the baud rates and '4' selects the parity.
