Specifications and Configurations
Section 1-2
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.

Programming Devices
A Programming Device for the PLC, the Controller Link Support Software, or
CX-Programmer are needed to use a Controller Link Network.
Programming Device for the PLC
One of the following Programming Devices is necessary when using the auto-
matically setting data links or the message service.
The following operations are possible.
• Selecting manual or automatic setting for data links.
• Setting the data link mode to “automatic” (software switch setting).
• Starting/stopping data links (Start Bit: ON/OFF)
• Programming for the message service.
• Reading (monitoring) the network status.
Note
1.
Use the CX-Net in CX-Programmer version 5.0 or higher to set data link
send and receive areas that exceed 12,000 words, and to set data link ta-
bles that allocate the same area for Area 1 and Area 2.
