Ladder logic mismatch modicon 984

5 posts in this topic

I have a ladder logic mismatch error on a modicon 984 using concept 2.6.  It also says not equal in right corner.  I am guessing it means the logic in the file doesnt match the processor?  Any easy fixes to this problem and is it a major problem?

read from PLC or Write to PLC
It's just a notice that your working file doesn't match the running file in the PLC

So further research I have found someone made a minor change to a input well online but did not download to the processor.  So if I download from concept this should fix the error? or do you recommend I upload ?

Upload if the process is running properly.

If you download, their change will be erased.
