ML1200 and 1762-IF4

2 posts in this topic

Hello all,

I have an Micrologix 1200 with 3 1762-IF 4 modules. The 1200 PLC recently failed and I put a new one in and loaded the same running program. When going to run, it faulted saying the program was set for modules not found in the PLC or modules were found that were not configured in the program. When I go to IO configuration in RS500, there all in there, but when I do the "Read IO Configuration" button, it comes up empty, it doesn't find the connected IF-4's. I am suspecting maybe the cards got damaged too? Or am I missing something?

Check and double check the flat ribbon cable between the controller and modules.
