Specifications and Configurations Section 1-2
Communications Cables
The following shielded twisted-pair cables are recommended for Wired Con-
troller Link Network connections.
Note Use the special connector provided with the Board to connect the Controller
Link Support Board to the network.
Relay Terminal Blocks
The following Relay Terminal Block can be used to make maintenance easier
by facilitating replacement of the Controller Link Unit after system operation
has begun.
Note Normally, the communications cable must be disconnected from a Wired Con-
troller Link Unit to replace it. Doing this, however, will interrupt communica-
tions on the network, requiring that all node be turned OFF to ensure safety
before replacing a Unit. With the above Relay Terminal Block, a Controller
Link Unit can be replaced by turning OFF only the specific Unit being
replaced, i.e., without turning OFF any other Units. The communications
cables are left connected to the Relay Terminal Block and only the Relay Ter-
minal Block is removed from the Controller Link Unit. (The built-in terminating
resistance connected at the Units at the end of the network prevents using the
Relay Terminal Block on the end Units.) Refer to
for details on using the Terminal Relay Block.
1-2-6 Programming Devices
A Programming Device for the PC, the Controller Link Support Software, or
CX-Programmer are needed to use a Controller Link Network.
Programming Device for the PC
One of the following Programming Devices is necessary when using the auto-
matically setting data links or the message service.
