I am an instructor at a technical school and am teaching control systems. The school bought AB 1747-demo units which consist of a SLC 5/02, 2 Inputs and one output unit prewired to switches and lights. Programming is via RSLogix. The problem is I have been totaly unsuccessful in establishing communications between the PC and the PLC. We have 1747-UICs (early verison A's) I have tried this with several UICs and several 5/02s (Particulalr with the track record I have heard with the early UIC)
When I connect everything up I get the OK light and when RSlinx is running the USB light blinks and the DH485 blinks. The Comm light on the 5/02 occasionaly blinks (very low intensity) I am using staight-thru Ethernet cables. I have reviewed he AB website and the posting on this web site and tried everything.
Details:
UIC com port 5 and 7
5/02 1747-l524 ser C
1747-UIC Ser A, Rev A
Default settings for Comm ports 1900/n/1
