Thank you very much.
I have managed to solved my problem.
The only problem was that "my logic was inverted".
My Easy 412 doesn't show selected settings by placing check mark next to menu item!
I saw text "Mode: run" <-- and I was thinking it is already in run mode --> so I exit the system menu.
All I had to do was to push the OK button to actually set the run mode.
So if you see "Mode: run", PLC is currently in STOP mode (and vice versa).
Thanks again,
Regards
Damjan
