Omron CJ1W-CORT21 Custom CAN Communication Module

The Omron CJ1W-CORT21 is a flexible user-defined CAN communication unit for CJ-series PLCs, enabling custom CAN messaging using 11-bit and 29-bit identifiers. Designed as a CPU bus communication module, it allows seamless integration with a wide range of CAN-based industrial devices in automotive, logistics, or machine-building environments.

With one CAN port and open-frame protocol support, the CORT21 is ideal for implementing tailored CAN communication structures not supported by standard network profiles.
