Messaging between AB DH+ and CIP
The 1756-DRHIO provides a way for information to be transfered between devices between PLC-5s, SLCs and other Controllogix for the following:
• Different network Communications between with PLC-5s or SLCs
• Different network Communications between ControlLogix processors and a PLC-5s or SLCs.
• Different network Communications Between ControlLogix processors.

Details on Data Highway Plus:

Data Highway Plus is a cable or wire with a protocol that provides intercommunication between PCs and devices.  The

networking cable used is named the network medium.  A DH+ connections moves data between PLCs on DH+ such as PLCs, SLCs and ControlLogix processors and other DH+ nodes. You can interface up to 32 stations to one DH+ connections.
