Hello everyone!
I have a control logix plc that is set up to communicate with 6 1794-asb flex i/o racks.
Everything has worked good over the years until about a month ago. They lost communication on rack 16, or 6, and we can't get it back.
Found a replacement module, no luck. Switched with a known good one. No luck. Just that stupid yellow triangle in studio 5000.
I was not the first guy to try and figure this out, and I can see dip switch settings in the original have been toggled, so no correct previously good settings are known.
I'm going to attach the configuration settings from studio to see if anyone can point us in the right direction.
Rockwell has been no help.
The old man that got me into pics is stumped.
I'm getting now gray hair every time I go out there.
It seems to be a rack size issue as you see from the pictures, but trying to figure out standard, compact and other addressing is confusing per rockwell instructions.
Halp.
