DHRIO configuration

The DH+ protocols do not use the ControlLogix source routing model. Therefore, the DHRIO module, as the entry point into the ControlLogix architecture from the DH+ network, is the source and must be provided a full route to deliver a message from the DH+ network through the ControlLogix architecture to the destination. You

must

configure each 1756-DHRIO module with a routing table that specifies the route from that module to each link ID that will be received by that module. To do this draw a diagram of your system for each 1756-DHRIO module and label appropriate links with link IDs.

You only have to do this once for each ControlLogix chassis. The configuration software will use the same routing table for each module in the chassis.
