The OMRON Controller Link Unit CS1W-CLK21-V1 is a high-performance, cable-type Controller Link Unit designed for seamless integration into OMRON’s CS1-series PLC systems. It provides a robust and deterministic network solution for real-time data exchange between controllers, supporting both large-scale and distributed control architectures.

Enhanced Ethernet Support and Connectivity

As Ethernet continues to establish itself as the global standard for information networks, the CS1W-CLK21-V1 strengthens its capabilities by offering extensive Ethernet-based functionality. In addition to core communication services such as FINS message transmission, FTP file transfer, and email notification, the unit now supports eight socket interfaces for both TCP/IP and UDP/IP protocols. This enables flexible and direct communication with a wide range of devices, allowing production management systems to be effectively and organically linked to the production floor.

Simplified Maintenance Data Access via Component/DeviceNet

The unit introduces dedicated explicit message instructions, which greatly simplify the process of sending Explicit messages without the need to handle complex FINS commands. This allows for straightforward reading of maintenance data from connected components and DeviceNet devices. Furthermore, data transfer between PLCs using Explicit messages is also streamlined, improving system maintainability and reducing development effort.
