Figure 233: Enabling PTP in ECT
The
PTP VLAN tag must have the same value in station clock and in the IED. The default value is
set to 0.
The
PTP VLAN tag does not need to be the same on all access points in one IED. It is possible
to mix as long as they are the same for all devices on each subnet.

Figure 234: Example system
Figure 234 describes an example system. The REC and REL are both using the 9-2 stream from
the SAM600, and gets its synch from the GPS. Moreover, the REL and REC both acts as a
boundary clock to provide synch to the SAM600. The REL contains a GTM card, which has a PPS
output that is used to synchronize merging units that are not PTP compliant. As a side effect,
the GTM contains a GPS receiver and the REL acts as a backup of the GPS on the station bus.
On all access points, the PTP parameter is “ON”.
On the REL, the parameter FineSyncSource (under Configuration/Time/Synchronization/
TIMESYNCHGEN:1/General) is set to “
GPS” if there is a GPS antenna attached.
If the GTM is used as a PPS output only, the
FineSynchSource is not set.

When process bus communication (IEC/UCA 61850-9-2LE protocol) is used, it is essential that
the merging units are synchronized with the hardware time of the IED (see Technical manual,
