The Omron C200H-RT201 Remote I/O Slave Module is a versatile and robust component designed for industrial automation systems. It operates on a wide range of power supplies, supporting 100 to 120 VAC and 200 to 240 VAC, and features a wired interface for reliable communication. This module is part of the C200H series and is specifically engineered to function as a remote I/O slave in a distributed control network.

The Host Link Unit, which is compatible with the C200H-RT201, facilitates direct connection to a computer, enabling comprehensive monitoring and control capabilities. Through this unit, users can monitor or modify the operating conditions of the Programmable Controller (PC), read and write data to the IR (Internal Relay) area, and extract or load programs. Each CPU or Expansion I/O unit can accommodate up to two Host Link Units, and communication is supported via RS-232C, RS-422, and plastic-sheathed fiber optic cables, including APF/PCF interfaces. The Host Link Unit can be integrated with other C-series units in a multi-drop configuration, and it is also compatible with programmable terminals. Advanced features include the use of transmission instructions (TXD) on C200HX/HG/HE models to initiate data transfer from the PC, as well as support for multi-level Host Link systems. For system and data loading, the C200H-LK101-PV1 (optical cable) allows connection between two personal computers.

In addition, the module supports the CompoBus/D (DeviceNet) protocol, functioning as a master unit in a multi-master bus system that is fully compliant with DeviceNet standards. This compatibility with Allen-Bradley DeviceNet enables seamless connection to a wide variety of devices. The use of dedicated cables significantly reduces wiring effort, as two nodes can be connected via a single cable, and the system supports T-branch, drop-line, and multi-drop wiring topologies. When used with C200HX, C200HG, and C200HE series master units, up to 50 slave units can be connected, providing up to 1600 points of I/O control. The network achieves high-speed communication of 125 kbps at distances up to 500 meters and 500 kbps at distances up to 100 meters. The CompoBus/B Configurator support software allows for I/O configuration changes on the master unit, and multiple master units can be used across up to seven CPUs.
