The Omron CS1W-EIP21 EtherNet/IP Unit adds high-speed EtherNet/IP connectivity to Omron CS1 PLC systems, enabling real-time data exchange across factory networks. This Ethernet communication module uses an RJ45 interface, mounts on the CS1 rack/backplane, is powered from the PLC rack, and supports tag data link and message communication for CS1 Series automation. Operating from 0°C to 55°C, it provides network and module status LEDs for quick diagnostics and is designed for use in manufacturing lines, process control, packaging machines, material handling, and robotics. Common replacements include CJ1W-EIP21, CS1W-ETN21, and CJ2M-CPU31.
