•
SYNCH signal on the MUx function block indicates that protection functions
are blocked due to loss of internal time synchronization to the IED (that is loss
of the hardware
synchSrc
).
•
MUSYNCH signal on the MUx function block monitors the synchronization
flag
smpSynch
in the datastream and IED hardware time synchronization.
No 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.

Setting example without time synchronization
It is also possible to use IEC/UCA 61850-9-2LE communication without time
synchronization.
Settings on the local HMI under
Main menu/Configuration/Time/
Synchronization/TIMESYNCHGEN:1/IEC61850-9-2
:
•
HwSyncSrc
: set to
Off
•
SyncLostMode
: set to
No block
to indicate that protection functions are not
blocked
•
SyncAccLevel
: set to
unspecified
Two status monitoring signals with no time synchronization:
