Routing ControlLogix to PLC5 via DH+ Gateway

Product catalog summary

Overview: This document provides a technical description of routing ControlLogix to PLC5 via a DH+ Gateway using KEPServerEX. It outlines the configuration and communication pathways between devices in an industrial automation setup.

Device Description: The KEPServerEX device with ID 192.168.111.116 is configured to communicate with a ControlLogix system and a PLC5 system. The ControlLogix system includes a Logix 5550 processor and various communication modules, including 1756-DHRIO and 1756-ENBT.

Communication Pathway: The communication pathway involves Ethernet and DH+ networks. The 1756-ENBT module provides Ethernet connectivity, while the 1756-DHRIO module facilitates communication over the DH+ network. The pathway is described as follows:

IP 192.168.111.116 corresponds to the 1756-ENBT module.
Port 1 of the 1756-ENBT module accesses the backplane of the ControlLogix PLC.
Slot 1 of the 1756-DHRIO module is used for DH+ communication.
Channel B of the 1756-DHRIO module connects to Node 9 of the target PLC5 device.

Interface Module Ports: The document details the port configurations for various modules:

1756-ENBT: Backplane to Ethernet Network.
1756-DHRIO: Backplane to DH+ Network on Channels A and B.
1756-CNB: Backplane to ControlNet Network.

Key Considerations: The document emphasizes the importance of correct port and node configurations to ensure seamless communication between ControlLogix and PLC5 systems. It also highlights the role of virtual backplanes in facilitating Ethernet/IP messaging.
