Specific settings related to the IEC/UCA 61850-9-2LE communication

The process bus communication IEC/UCA 61850-9-2LE has specific settings, similar
to the analog inputs modules.
If there are more than one sample group involved, time synch is mandatory. If there is
no time synchronization, the protection functions will be blocked due to condition
blocking.
CTStarPointx: These parameters specify the direction to or from object. See also
section "Setting of current
SyncLostMode: If this parameter is set to Block and the IED hardware time
synchronization is lost or the synchronization to the MU time is lost, the protection
functions in the list 74 will be blocked due to conditional blocking. If this parameter
is set to BlockOnLostUTC, the protection functions in list
hardware time synchronization is lost or the synchronization of the MU time is lost or
the IED has lost global common synchronization (i.e. GPS, IRIG-B or PTP). SYNCH
output will be set if IED hardware time synchronization is lost. MUSYNCH output will
be set if either of MU or IED hardware time synchronization is lost.
Loss of communication when used with LDCM
If IEC/UCA 61850-9-2LE communication is lost, see examples in figures 327,
