Controller Link Units can be mounted to C200HX/HG/HE CPU Racks to create
automatic data links that can be freely set between C200HX/HG/HE, CVM1,
and/or CV-series PCs. Controller Link Support Boards are also available so that
IBM PC/AT or compatibles can also be included in the Controller Link System.
Controller Link Systems support a message service that can be used as
required for communications using the SEND and RECV instructions. An exam-
ple configuration for C200HX/HG/HE PCs is shown below.

Controller Link Systems are wired using multidrop connections with twisted-
pair cable. Each System can include up to 32 nodes and can extend up to 1 km
for 500-Kbps communications and up to 500 m for 2-Mbps communications.
•
For data links, each PC node can read/write up to 8,000 words and each com-
puter node, up to 32,000 words. The data link words can be either set automati-
cally or that can be set manually to more efficiently meet the needs of specific
applications using Controller Link Support Software.
•
The message service can be used to send up to 2,012 bytes of data at a time.
•
A Communications Board (C200HW-COM01/COM04-EV1) and a Bus Con-
nection Unit (C200HW-CE001/CE002/CE012) are required to mount a Con-
troller Link Unit to a C200HX/HG/HE PC.
•
The Controller Link Unit cannot be used with the C200HE-CPU11-E/ZE.
