Here you may select the time standard for internal time stamping. For the master
device you may select from the following modes:
The RTC continues running, even when the auxiliary voltage is temporary absent, by
means of an internal battery. During the device powering up, or if the auxiliary voltage

Item Operating Mode Explanations
1I
nternal Clock Internal synchronization using RTC
2 IEC 60870–5–103 External synchronization using the system interface and the IEC 60870–
5–103 protocol
3 IR
IG B Time signal External synchronization using IRIG B
4 DCF77 Time signal External synchronization using DCF 77
5 SIMEAS time signal Sync. Box External synchronization using SIMEAS Sync. Box
6 Pulse via binary input External synchronization with pulse via binary input
7 Fieldbus External synchronization via fieldbus
8 Internal or Timing Master Only for devices with digital communication way:
as above No. 1 to 7; normally, however, the time is synchronized by the
absolute timing master. Only when the protection data communication
with the absolute time master fails, is the synchronization accomplished
via the indicated source.
