Time-of-day synchronization
Synchronization method of the CP
Note
Time-of-day synchronization of the CP
With applications that require time-of-day synchronization (e.g. telecontrol), you need to
synchronize the time of day of the CP regularly. If you do not synchronize the time of day of
the CP regularly, there may be deviations of several seconds per day in the time information
of the CP.
With security functions enabled, you need to enable time-of-day synchronization.
Note
Recommendation for setting the time
Synchronization with a external clock at intervals of approximately 10 seconds is
recommended. This achieves as small a deviation as possible between the internal time and
the absolute time.
