Configure the Module Switches
In this application, you must set switches on the 1756-DHRIO and
1756-DHRIOXT modules for DH+ and the switches on the 1756-CNB
modules to the correct node addresses. The 1756-CNB module in system
number 1 uses node address 22 and the 1756-CNB module in system number 2
uses node address 23.
Configure a Routing Table for the Module
Use RSLinx software to configure a routing table for the 1756-DHRIO and
1756-DHRIOXT modules. The following figure shows the routing table
necessary for this example.
IMPORTANT
The switches on the 1756-CNB modules must match the information in the
1756-DHRIO routing table.
