i've tried to run some Graph program on plcSim but there's a problem that after runing for nearly 2 minute it's finished although my program uses a forever loop.
here's the pisture of plcSim when the problem occured:
i mean when the problem hadn't occured, the light SF on plcsim didn't turn to red color, but after running about 2 minutes, it turned to red color as in the picture above.
and here is my program:
hope someone can give me an explaination ? and how i can solve it ? thanks !^~^
