Application manual
If PTP is activated, the device with the best accuracy within the synchronizing
group will be selected as the source. For more information about PTP, see the
Technical manual.
IEEE 1588 (PTP)
PTP according to IEEE 1588-2008 and specifically its profile IEC/IEEE 61850-9-3
for power utility automation is a synchronization method that can be used to
maintain a common time within a station. This time can be synchronized to the
global time using, for instance, a GPS receiver. If PTP is enabled on the IEDs and
the switches that connect the station are compatible with IEEE 1588, the station
will become synchronized to one common time with an accuracy of under 1us.
Using an IED as a boundary clock between several networks will keep 1us
accuracy on three levels or when using an HSR, 15 IEDs can be connected in a ring
without losing a single microsecond in accuracy.

Setting guidelines

All the parameters related to time are divided into two categories: System time and
Synchronization.
System time
The time is set with years, month, day, hour, minute, second and millisecond.
Synchronization
The setting parameters for the real-time clock with external time synchronization
are set via local HMI or PCM600. The path for Time Synchronization parameters
on local HMI is Main menu/Configuration/Time/Synchronization. The
parameters are categorized as Time Synchronization (TIMESYNCHGEN) and
IRIG-B settings (IRIG-B:1) in case that IRIG-B is used as the external time
synchronization source.
TimeSynch
When the source of the time synchronization is selected on the local HMI, the
parameter is called TimeSynch. The time synchronization source can also be set
from PCM600. The setting alternatives are:
FineSyncSource which can have the following values:
• Off
• SPA
• LON
• BIN (Binary Minute Pulse)
• GPS
• GPS+SPA
• GPS+LON
• GPS+BIN
