Morning,

I had the same problem with more or less the same cpu and even with the software I could not remove the simulation mode that desactivate the outputs. Program was running but without the outputs it was just a very poor christmas tree...
The constructor send us back a new processor, we put the memory cartridge into it and it was ok. We didn't understood why this cpu went in simulation mode by itself. This generation of Hitachi plcs was very weird.
