4.7.2 Date/Clock Management
The integrated date/clock management enables the exact timely assignment of events
e.g., those in the operational annunciations and fault annunciations or in the lists of
the minimum/maximum values. The time can be influenced by
•
the internal clock RTC (Real Time Clock),
•
external synchronisation sources (DCF77, IRIG B, SyncBox, IEC 60870-5-103,
IEC 60850),
•
external minute pulses via binary input.

Double-click Time Synchronization . The Time Synchronization & Time Format di-
alog box opens (Figure 4-35, page 86).
Note
Upon delivery of the device the internal clock RTC is always set by default as synchro-
nisation source, regardless of whether the device is equipped with a system port or
not. If the time synchronisation is to be accomplished by an external source, you must
select the latter.
