When trying to launch the PC Runtime simulation the load option disappeared but it is only possible to load the target PC. Has the same thing happened to anyone? Thank you Attachment TiaP V18 upd4.PNG (552 Downloads)

So you start the simulation of the whole PC station. Have you tried to start the simulation with the WinCC Unified PC RT selected? Kind regards Stefan
