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.
20.13.2 Setting guidelines
All the parameters related to time are divided into two categories: System time and Synchronization.
20.13.2.1 System time
The time is set with years, month, day, hour, minute, second and millisecond.
20.13.2.2 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 can have the following values:
• Disabled
• SPA
• LON
• BIN (Binary Minute Pulse)
• GPS
• GPS+SPA
• GPS+LON
• GPS+BIN
• SNTP
• GPS+SNTP
• IRIG-B
• GPS+IRIG-B
• PPS
CoarseSyncSrc which can have the following values:
• Disabled
• SPA
• LON
• DNP
• IEC 60870-5-103
