That message indicates that a parameter setting in the project is not correct. Are you certain the program is configured for the right CPU type? Bot the FX and MEDOC are extremely out of date. Perhaps the PLC battery went dead and the PLC is blank? As it indicated, you can always try to clear all PLC memory and download your program again.
