5-2 Connecting to the Host Using Controller Link
This section explains the method for connecting to the host using a Controller Link Interface
Unit.
5-2-1 What Is a Controller Link Network?
A Controller Link Network is an FA Network that can send and receive large data packets
flexibly and easily among the OMRON C200HX/HG/HE PLC Programmable Terminal (PTs),
SYSMAC CS-series PLCs, CJ-series PLCs, CQM1H-series PLCs, C200HX/HG/HE PLCs,
CVM1/CV-series PLCs, IBM PC/AT or compatible computers, and NS-series PTs. The Con-
troller Link supports data links that enable data sharing and a message service that enables
sending data 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 or optical fiber cable. In addition,
the Controller Link Network can transfer large quantities of data at high speed, so that it is
possible to construct a wide-area network easily that supports from low-level systems to high.
For details on data links and message service, refer to the Controller Link Support Board Op-
eration Manual (W307), Controller Link Support Board for PCI Bus Operation Manual (W383),
and the Controller Link Unit Operation Manual (W309).
Note: An optical fiber cable is not available for NS-series PTs.
To connect the PT to the Controller Link, it is necessary to install a Controller Link Expansion
Board on the PT. Refer to 3-8 Installing the Controller Link Expansion Board for the procedure
for installing and wire the Controller Link Expansion Board.
When communicating by Controller Link, the network number, node number, routing tables,
and data link tables must be set. For details, refer to Section 7 System Settings in the NS Se-
ries Operation Manual.
