Hi, As already stated in the documentation it is possible to have explicit state entry into another submachine within a state machine. Is there a possibility to have a state machine, which has another submachine with explicit state entry and that submachine has another submachine with an initial transition. I put that together in a picture and attached it. I hope then it gets clearer what I want to do. The picture shows just a simplified version of the overall state machine and I discarded some other states, transitions and orthogonal regions. How do I have to declare the transition table and states in that case? Are there any restrictions regarding nested depth? Best Regards, Michael
