Q. How do I add a 1771-ASB adapter module to my SLC
1747-SN scanner remote I/O network?
A. Enter the correct rack number, rack size and starting group in
the SLC500 program I/O configuration G-file data screen.
With the correct communication rate set on the scanner,
download the program to the SLC processor and switch to
Run mode. Communication to the adapter will commence.
Q. Ever since I installed fiber optics on my remote I/O network,
the adapters won’t communicate.
A. This is probably an installation issue. Check your installation
for the correct application, connection and termination of
fiber optic cable, and the correct setup of the fiber optic
module (1771-AF, -AF1). Make sure that no length of blue
hose on this network is less than 10ft long, including the
blue hose connections from the processor, scanner or adapter
to the fiber optic module in the same chassis.
Q. I have a 12-slot chassis but only the modules in the first 8
slots are recognized by my program.
A. Check the scan switch (switch S2, position 4) for correct
setting. It probably is set ON “scan all but the last 4 slots.”
Set it to OFF.
