Allen-Bradley 20-COMM-E Ethernet Communications Adapter

Allen-Bradley 20-COMM-E Ethernet Communications Adapter is a PowerFlex architecture EtherNet/IP to DPI communication module that adds Ethernet connectivity to compatible PowerFlex drives. It enables an EtherNet/IP network to command the drive and return diagnostics via the DPI data path, so a PLC or SCADA system can control speed, enable/disable, and monitor drive health. This module plugs into PowerFlex drives that support 20-COMM-E and is documented as the EtherNet/IP Adapter for PowerFlex, often described in Rockwell literature as the ENet communications adapter. As part of the 20-COMM family, the 20-COMM-E is designed to integrate with Rockwell Automation control systems using EtherNet/IP protocol for device communication and data exchange with controllers. Typical applications include integrating PowerFlex drives into automated lines or machine controls where centralized PLCs coordinate multiple drives over Ethernet/IP to achieve synchronized motion, remote monitoring, and simplified wiring. The adapter supports standard EtherNet/IP communications and provides the DPI interface required for drive-to-controller data exchange.
