The CJ1W-EIP21 is a high-performance EtherNet/IP communication unit designed for the Omron CJ-series programmable logic controllers. This unit enables industrial multivendor network communication using Ethernet and is managed under the ODVA open standard. It supports tag data links with a capacity of 180,000 words or more, allowing efficient data exchange with up to 256 nodes over up to 256 connections without requiring programming. The unit provides both FINS/UDP and FINS/TCP functionality for message services and features 100Base-TX Ethernet connectivity. It mounts on the CPU rack or expansion rack as a CPU Bus Unit and includes an RJ45 connector for shielded twisted-pair cable. The CJ1W-EIP21 is ideal for applications requiring high-speed, real-time data sharing across distributed control systems in manufacturing, process automation, and industrial networking environments.
