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.
