Settings on the local HMI under Main menu/Configuration/Time/
Synchronization/TIMESYNCHGEN:1/General:
• fineSyncSource can be set to something different to correlate events and data to
other IEDs in the station.
Two status monitoring signals can be:
• SYNCH signal on the MUx function block indicates that protection functions are
blocked due to loss of internal time synchronization to the IED.
• MUSYNCH signal on the MUx function block monitors the synchronization flag
smpSynch in the datastream and IED hardware time synchronization.
SMPLLOST indicates that merging unit data are generated by internal substitution or
one/more channel's Quality is not good or merging unit is in Testmode/detailed
quality=Test, IED is not in test mode.
Using external clock for time synchronization
This example is not valid when GPS time is used for differential
protection, when PTP is enabled or when the PMU report is used.
