  1. Decoding PLC Program Help

    Let me preface by saying I am brand new to working with plc. I am working with a Mitsubishi FX series that is hooked up to a heater control module. The HMI is giving a thermal error on screen. I have  downloaded the program from the plc and am having difficulty figuring out what section of the program contains the heater control module. Is there a certain string of code combination that would be a place to start? I think it is looking for/measuring a value for a thermocouple that is not there thus giving the error and my idea was to find it in the program and close the connection.   Edit: I attached the file.
