Product Description

New PLC CJ1W CJ1W-CLK23 Omron Controller With One Year Warranty


• Large-capacity data links are easily achieved without programming simply by setting data link tables.

• Up to 20,000 *1 send/receive words can be set per node for Units (up to 62,000 words for Boards).

• Data links can be performed with up to 4,000 *2 words per node while ensuring data concurrency.

• User-set data link tables can be changed while data links are operating. *3

• Errors for the entire system can be monitored by using error diagnosis support software and a variety of status flags.


*1. Supported for unit version 1.2 or later.
*2. CJ1W-CLK23 and 3G8F7-CLK[]3 are supported.
*3. Supported for CJ1W-CLK23, 3G8F7-CLK[]3, and models ending with "-V1".

*1. Discontinuation models in July 2012.
*2. With wired models, the maximum number of nodes is 32 if Repeater Units are not used. A Repeater Unit is required
       when building a network with more than 32 nodes. If a Repeater Unit is used, be sure to use only the following
       Controller Link Units or Boards and set the Wired Network 62 Node Enable Bit in the DM Parameter Area software
       switches at all nodes.
*3. CX-Net in CX-Programmer version 3.1 or earlier can be used only in a system with a maximum of 32 nodes (node
       address 1 to 32). If a system is to be used with a maximum of 62 nodes (node addresses 1 to 62), use CX-Net in
       CX-Programmer version 3.2 or higher or the CX-Integrator.
*4. CJ-series PLCs do not have a Link Area, but LR000 to LR199 are automatically converted CIO 1000 to CIO 1199
