Product Introduction
The Allen-Bradley 20-COMM-ER PowerFlex EtherNet/IP Dual Port Communication Adapter is a high-performance communication interface designed for SMC and PowerFlex 7-class drive systems. It enables seamless integration of drives into EtherNet/IP industrial networks, supporting advanced control, monitoring, and diagnostics functions.
This adapter features a dual-port Ethernet design, allowing it to operate as an embedded switch within the network. It supports flexible network topologies such as star and linear (daisy-chain), reducing the need for external Ethernet switches and simplifying system wiring.
The 20-COMM-ER converts internal drive communication via DPI (Drive Peripheral Interface) into EtherNet/IP protocol, ensuring real-time data exchange with PLC systems. Its compact design allows direct installation onto compatible drives, making it an efficient solution for upgrading communication capabilities in industrial automation systems.
