Communication Interface Modules
In order for the OPC Server to communicate with a Controller, one or more Communication Interface
modules must be configured. In addition to defining the IP addresses that are used in the Controller
Details dialog, a Modbus slave must be configured. The Slave Address must be set to the same value
as the Comms ID Number defined in the Controller Details dialog. Communications should be set to
“Wait TCP/IP Connection” for port 2000. Please see the Product Description PD-8151B for the
Communication Interface for further configuration details.
In the Controller system configuration, the Communication Interface Connection Timeout is used to
determine if an Ethernet link has failed. If the Trusted
TM Communication Interface module has an open
Ethernet connection that has not sent or received any data for this period, the Ethernet connection will
be closed. This ensures that any Ethernet connection that has failed is released so that it can be re-
used. The value should be considerably larger than the other timeouts. A value of 300 seconds (5
minutes) is usually suitable.
2.5.2. Real-time Clock
The date and time settings for the Controller should be synchronised with the date and time of the PC
hosting the OPC Server application.
