1-12 Installing Your ControlNet PLC-5 Processor
Specifying the Serial
Interface of Channel 0
Specify RS-232C, RS-422A, or RS-423 communication for Channel
0 by setting the switches of assembly SW2.
Selecting the ControlNet
Network Address of
Channel 2
Select your processor’s ControlNet network address by setting the
two 10-digit rotary switches on the top of the processor.
You can select from as many as 99 network addresses (from 01 to 99)
for a processor on a ControlNet link. 0 is invalid.
Important: Do not power-up the processor if the processor’s
ControlNet network address is set to 0. If you do, you
will not be able to communicate with your processor and
your ladder program will be lost, even if you have a
battery installed. If this happens, select a valid network
address for the processor and cycle power.
