Supported Communication Interfaces

This appendix documents the redundant communication interfaces supported by Server Redundancy.

The supported redundant communication interfaces are:

Series 90 TCP/IP




Allen-Bradley Communications

DDE Client

Modbus RTU

Modbus TCP/IP

OPC Client

Point Bridge

Series 90 TCP/IP Triplex Device Communications

In addition, CIMPLICITY supports the development of Server Redundant Device Communication Toolkit drivers. Use the heartbeat function in the enabler to determine if the secondary server can communicate with its configured devices.
