Set-Up a Routing Table for the 1756-DHRIO Module
1. Use the ControlLogix Gateway Configuration Tool (1756-
GTWY) to set-up a routing table for the 1756-DHRIO module.
Your table should look like this:
2. Apply the routing table to your application.
Important: Controller slot values for channels configured for DH+
should be applied or restored to default value, using the
appropriate software tabs.
In this example, controller values do not matter, but
failure to enter a value, specific or default, will generate
a configuration fault for that channel.
For more information on how to set-up a routing table using the
ControlLogix Gateway Configuration Tool (1756-GTWY), see
publication 1756-6.5.7.
