The Omron CJ1W-CLK23 PLC Controller Link Unit provides controller-to-controller communication within distributed Programmable Logic Controller networks. It supports a transmission speed of 1 Mbps and up to 32 nodes per network, allowing multiple controllers to exchange operating information through a shared communication architecture. A data link capacity of 10,000 words supports the transfer of control data between connected nodes, while token-passing communication coordinates network access. This communication layer supports applications where separate PLC controllers must share process and machine information as part of a larger automation system. The CJ1W-CLK23 extends CJ1W controller networking and belongs to the PLC data link communication range supporting Omron control architectures.
