Best practice
Use SuperState_WithBusyFinal instead of a standard State. This helps to understand the process. Normally an action must be carried out prior to each target state. This is done in this concept in the busy state.
- Enter 'PON' (power on) as name for the SuperState
- Create three other SuperStates (OFF, POS1, POS2)
- Connect the states according to the picture
Pay close attention to the origin and the target of each transition.
