Explanation of the transitions during system start
While a state is passed through, different tests are carried out (e.g. it is tested whether the
physical topology complies with the configuration). If the tests are successful, the system
automatically changes to the next state.
Detailed information about the possible bus states and the required commissioning steps
can be found here:
