An energy-saving profile runs through the displayed automatic state machine if the associated
"energy-saving profile initialized" bit is set. The HMI resets this bit before changing the times
or the signal mask, and sets it after the values have been consistently written into the PLC.
When the "Energy-saving profile active" bit is set, then an energy-saving profile is considered
to have been assigned.
