Create the Routing Table
To create a routing table for your application, follow these steps:
1.
Start RSLinx.
2.
Browse the network.
3.
Use the left-side navigation bar to see your DH+ application, as shown in 
the following example.
4.
When the 1756-DHRIO Configuration pop-up appears, select the 
DHRIO Routing Table tab. 
You must use RSLinx software to build the routing table based on the 
1756-DHRIO and 1756-DHRIOXT modules in the ControlLogix 
chassis. Each link ID (that is chassis backplane, channels A and B of any 
1756-DHRIO and 1756-DHRIOXT modules in the chassis) is initially 
undefined.
1. Expand the configuration tree until
your application appears on the right 
side of the dialog box.
2. Right-click the 1756-DHRIO or 1756-
DHRIOXT module’s icon to see the 
menu.
3. Click Module Configuration.
