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 (PCs), CS-series PCs, CJ-series PCs, CVM1 PCs, CV-series
PCs, CQM1H-series PCs, 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.
The network is connected using shielded twisted-pair cable and high-volume
data transmissions at high speed enable construction of a wide range of net-
works, from low-level systems to high. (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.

Data Links
Data links allow the constant sharing of data in predetermined data areas
between nodes, between PCs, or between a PC and an IBM PC/AT or com-
patible computer on the network. Data links do not require the use of commu-
nications programs on the PC (CPU Unit) or IBM PC/AT or compatible
computer. Data written in the send area of the local node will be automatically
sent to the receive area of other nodes.
