We had a storm last night, and the smoke got let out of some of our PLC equipment. I'm troubleshooting a link between a 1747-SN and a 1747-ASB.
Both of their dip switches for the baud rates are set the same (0 1).
When powering up, the 1747 ASB gives the following messages:
Red Fault LED on with PUP
Red Fault LED flashing with bnc
The 1747 SN powers up
Fault LED turns on
Coms LED turns green
Coms LED turns orange
Both LEDs turn off.
I'm a bit stumped here. I didn't do the replacements, but the tech told me that he set the dip switches as they were before. I verified this the best I could, but it seems like we have a communication issue, and I'm leaning towards the 1747-ASB.
Can the cards on the remote rack be placed in any position and still work fine given that there is only one IO scanner? We have several spots in the rack that are unused.
