ControlLogix DH+ Network Communication Overview
Communicate over a DH+ Network
For the controller to communicate to a workstation or other device
over a DH+ network, use RSLinx software to:
•
specify a unique link ID for each ControlLogix backplane and
additional network in the communication path.
•
configure the routing table for the 1756-DHRIO module.
The 1756-DHRIO module can route a message through up to four
communication networks and three chassis. This limit applies only to
the routing of a message and not to the total number of networks or
chassis in a system.
