Description
Product Description
The 20-COMM-C is a ControlNet communication adapter developed by Allen-Bradley for integration of PowerFlex drives and compatible motor control products into ControlNet industrial networks. The module serves as a communication bridge between the drive DPI interface and ControlNet architecture, enabling deterministic high-speed data exchange for automation and motion applications.
This adapter is designed for installation in PowerFlex drive families and selected Rockwell Automation motor control platforms. It supports scheduled and unscheduled messaging over ControlNet and allows centralized monitoring, parameter access, diagnostics, and control from PLC or SCADA systems.
The compact module includes dual coaxial network ports, onboard node-address switches, and LED diagnostics for simplified commissioning and maintenance.
