Omron C200H-LK201 Host Link Unit

The Omron C200H-LK201 Host Link Unit is a dedicated communications interface for Omron C200H PLC systems, providing the essential link between a C200H controller and a host device. This Host Link Unit enables data exchange and command communication within Omron automation configurations, supporting standard Host Link workflows that move programming traffic, parameter updates, and runtime monitoring data between a host computer or other control system and the PLC. In typical deployments, the LK201 acts as the PLC’s communications bridge within compatible C200H configurations, facilitating integration with development workstations, supervisory systems, or other devices that interact with the control logic. The part is identified by the C200H-LK201 designation and is used wherever a Host Link connection is required in Omron C200H setups. In practice, the LK201 serves as a dedicated interface to enable host-based programming, diagnostics, and data exchange across the Omron C200H ecosystem.
