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.

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.
