I have a compact logix with a major fault.
Please see my attached file for the complete fault message.
Code 20 array subscript too large. or control data type to large or invalid.
Has anyone observed this issue before. The PLC is a compact logix model. Every time, the controller is switched from program to run the major fault occurs within 5 seconds. The fault can be cleared but then it comes back in a few seconds. I have been told by my tech that no program changes have been made. Could there be a hardware/wiring issue?
Thanks much
