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 (R
eal Time Clock),
• external synchronisation sources (DCF77, IRIG B, SyncBox, IEC 60870-5-103,
IEC 60850),
• external minute pulses via binary input.
Time
synchronization
You find the parameters for the clock management in DIGSI at Settings → Time Syn-
chronization (Figure 4-34, page 85).
Figure 4-34 The window Settings in DIGSI − Example
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.
