TIMESYNCHGEN:1/IEC61850-9-2:

HwSyncSrc : is not used as the SW-time and HW-time are connected with each other due to

SyncLostMode : set to Block to block protection functions if time synchronization is lost

common synchronization is lost

SyncAccLevel : can be set to 1μs since this corresponds to a maximum phase angle error of

0.018 degrees at 50Hz

Operation: On

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

in the datastream and IED hardware time synchronization.
