21.13.2.3 Process bus IEC 61850-9-2LE synchronization
When process bus communication (IEC 61850-9-2LE protocol) is used, it is essential that the
merging units are using the same time source as the IED. To achieve this, a satellite-controlled
clock shall provide time synchronization to the IED (either internal GPS or via IRIG-B 00x with
IEEE1344 support) and to the merging units (via for instance PPS). For the time synchronization of
the process bus communication, GPS Time Module (GTM) and/or IRIG-B module can be used. If the
IED contains a GTM, the merging unit can be synchronized from the PPS output of the GTM.

SyncMaster defines if the IED is a master, or not a master for time synchronization
SyncMaster can have the following values:
Set the course time synchronizing source (
time synchronization of line differential function is used. Set the fine time
synchronization source (
complete time synchronization. GPS alone shall synchronize the analogue values in
such systems.
All protection functions will be blocked if the AppSynch parameter is set to Synch
while there is no 9-2 synchronization source. For more information please refer to
the "IEC/UCA 61850-9-2LE communication protocol" section.
