Hi

I created a new project in SIMIT and created a ProfibusDP table.

I compiled the project and hit the play button and everything seemed to be working. However, whenever we hit the stop button, the computer locks up. No keyboard input or mouse is available.

There is another project in SIMIT that does start/stop just fine.

The SIMIT version is 5.4 (no SP1). The project that starts/stops was created using PCS7 SP1. The project that locks up was created using PCS7 SP2.

Any ideas? We're stumped.

Thank you
