Perform the following steps to make proper I/O channel connections:
Step 1—Connect the twinaxial cable in a serial (daisy chain) fashion from
the 1775-S4B scanner to each I/O chassis within the I/O channel
(figure 3.8).
Step 2—Connect the signal conductor with blue insulation to the LINE 1
terminal at the 1775-S4B scanner and at each I/O adapter module in the
I/O channel.
Step 3—Connect the signal conductor with clear insulation to the LINE 2
terminal. Connect the shield drain wire to the SHIELD terminal.
Step 4—Connect a Terminator (cat. no. 1770-XT) between the terminals at
each end of each I/O channel.
You can optionally connect a normally open, momentary contact switch
between terminals 11 and 12 at each I/O adapter module. You could then
use such a reset switch to reset the I/O adapter module if the PLC-3
processor detects a fault at the I/O chassis. Refer to the PLC-3
Programmable Controller Installation and Operation Manual (publication
1775-6.7.1, formerly 1775-800) for detailed information.
