EtherNet/IP Communication Module for Omron CJ/CS-Series Programmable Logic Controllers

The Omron CS1W-EIP21S is an industrial EtherNet/IP communication module designed for seamless integration of CJ/CS-series PLCs into modern factory automation networks. This module facilitates secure, high-speed data exchange and control between the PLC and a wide range of EtherNet/IP-compatible devices, including HMIs, drives, sensors, and other controllers from multiple vendors. Supporting standard CIP (Common Industrial Protocol) services—including Explicit Messaging for parameter configuration and Implicit Messaging (I/O connections) for real-time control data—the CS1W-EIP21S enhances system flexibility and interoperability. It features a built-in Ethernet switch for daisy-chain wiring, simplifying cabinet layout and reducing installation costs. With support for up to 64 connections and advanced security features to protect your industrial network, this module is essential for building scalable, future-proof, and efficient control systems in manufacturing, packaging, and material handling applications.
