Set the course time synchronizing source (CoarseSyncSrc) to Disabled
when GPS time synchronization of line differential function is used. Set
the fine time synchronization source (FineSyncSource) to GPS. The
GPS will thus provide the complete time synchronization. GPS alone
shall synchronize the analogue values in such systems.
IEEE 1588 (PTP)
Precision Time Protocol (PTP) is enabled/disabled using the Ethernet configuration
tool /ECT) in PCM600.
PTP can be set to On,Off or Slave only. When set to Slave only the IED is connected to
the PTP-group and will synchronize to the grandmaster but cannot function as the
grandmaster.
A PTP-group is set up by connecting the IEDs to a network and enabling PTP. To set
one IED as the grandmaster change Priority2 to 127 instead of the default 128.

Figure 236: 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.
