Hey guys i have had another go with my only-run-mode PLC 5/40.
I connected threw the serial, still in run mode.
I switched the keyswitch in every order possible, still in run mode
Turned it off and on, still in run mode
Checked for errors, none
Checked the code for S:, nothing in the code
Checked the incoming messages, nothing to do with S:
Tryed to download a new progrm, declined "im in run mode"
Loaded the code into a spare processor, works fine
To me this is a bung processor
My only other option is pull the power and battery and clear the memory which holds the risk of not being able to reinstall the program.
Bung processor = replace processor
Thanks Guys for the help
