If the operator was not modifying code via the MEDOC software, then chances are all he did was entered a value into a register which does not compute with your system. Especially if the program matches, then it tends to be an issue with the data being read by the program. Check what values the operator was changing and look at how they are used in the program. Also, A1S-S and A2S-S are not valid part numbers. Please post a complete part number. It's written on the front of the CPU. If you want to put a program into a different model of CPU, then you need to change the PLC type in the project. You cannot just download it to the wrong hardware, it checks for that.

I have not touched MEDOC in forever, i don't remember the menus. You need to consider GX Developer to get something Windows based.
