After the start, the gauge independently runs through the INIT and SELFTESTING
status and eventually changes to the IDLE status (if there is no error) or to the
SELFTEST_EXCEPTION status (if there is a gauge error).
When data traffic is taken up, a difference has to be made between cyclic and
acyclic data traffic.
As soon as cyclic data interchange is taken up, the gauge automatically changes to
the EXECUTING status.
In acyclic data traffic, a START service has to be transmitted to bring the gauge to
the EXECUTING status.
