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, CVM1 PLCs, CV-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 at high speed enable construction of a wide
range of networks, from low-level systems to high.
A Controller Link Network can be connected by either shielded twisted-pair
cable or fiber-optic cable. For details on networks using twisted-pair cable
(i.e., Wired Systems), refer to the Controller Link Unit Operation Manual
(W309).
The functions of a Controller Link Network are outlined below.
