1-1-1 What Is the Controller Link?

The Controller Link is an FA network that can send and receive large data packets flexibly and easily among the OMRON C200HX/HG/HE Programma- ble Controllers (PLCs), CS-series PLCs, CJ-series PLCs, CVM1 PLCs, CV- series PLCs, CQM1H-series PLCs, and IBM PC/AT or compatible computers.

The Controller Link supports data links that enable data sharing and a mes- sage service that enables sending and receiving data when required. Data link areas can be freely set to create a flexible data link system and effectively use data areas.

High-volume data transmissions are possible at high speed and so a wide range of networks, from low-level systems to high, can be easily created.

There are two types of networks: networks connected with shielded twisted- pair cable and networks connected with optical fiber cable. Using a Repeater Unit in networks connected with twisted-pair cable makes it possible to use a variety of different wiring configurations, such as T-branch wiring, long-dis- tance wiring, and partial conversion to optical fiber. (Refer to the CS1W- CLK12, CVM1-CLK12 Optical Ring Controller Link Units Operation Manual (W370) for detail on optical fiber connections.)

The functions of a Controller Link Network are illustrated below.
