I have a simple logic for partition control running with a Pascal Controller. I also use that controller as my program interface (i.e. no PCI). However, it seems that the logic engine stops running every time I download changes using toolkit. (I am no sure but the logic doesn't respond anymore) Since I have no idea how to "re-activate" the logic engine, I re-load the logic program file to make it run again. Do I miss something fundermental in using logic engines?
