you mean, click the **Entry point** , choose **Main,** then chose a path to the main sequence box?

yes??i have done that, doesn’t help.
and each time I want to simulate, I need to use F5 to go to the virtual controller interface. change the controller to automatic model and click PP to main motor on, and at last close the virtual controller window. then I click the simulation button, it works. but I don’t konw why.

If you go to Program tab and browse to rutine, is there a main rutine in there, and what is in it.
