Product Description:

The Allen-Bradley 20-COMM-E Series B is a Remote I/O communication module that enables older Allen-Bradley controllers, primarily PLC-5 and some SLC 500 applications, to interface with Ethernet networks. This module provided a crucial link for these legacy systems to communicate with other devices on the network, allowing for data exchange, programming, and monitoring.

This particular module supports 10/100 Mbps Ethernet communication, which was a standard for its time. It allowed these older controllers to participate in modern network architectures, extending their lifespan and functionality.

Important Information for Legacy Systems:

The 20-COMM-E and the systems it supported (PLC-5 and older SLC 500s) are considered legacy technology. While this module may be necessary for maintaining existing installations, it's not recommended for new projects. Rockwell Automation strongly recommends migrating to newer platforms like ControlLogix or CompactLogix for new applications.
