Allen-Bradley 22-COMM-C PowerFlex ControlNet Communication Adapter

Allen-Bradley 22-COMM-C is a Drive System Interface (DSI) PowerFlex ControlNet communication adapter that installs in PowerFlex PF40 and PF400 drives to provide a dedicated ControlNet interface for the PowerFlex 4-Class family. As a PowerFlex Component Class device, it enables configuration, status reporting, and control messaging over a ControlNet network at the standard 5 Mbps data rate, with dual coaxial connections to support trunk redundancy and multicast communications for efficient network traffic. This adapter is the approved option for integrating PowerFlex drives into ControlNet systems, allowing centralized PLC or HMI access to drive parameters and status while retaining local drive control. Typical applications include automated manufacturing cells and packaging lines where PF40 or PF400 drives must communicate reliably on a ControlNet backbone.
