The parameter SyncMaster defines if the IED is a master, or not a master for time
synchronization in a system of IEDs connected in a communication network
(IEC61850-8-1). The
SyncMaster can have the following values:
• Off
• SNTP -Server
The time synchronization fine tunes the clock.
IEC 60870-5-103 time synchronization
An IED with IEC 60870-5-103 protocol can be used for time synchronization, but for
accuracy reasons, it is not recommended. In some cases, however, this kind of
synchronization is needed, for example, when no other synchronization is available.
First, set the IED to be synchronized via IEC 60870-5-103 either from IED
Configuration/Time/Synchronization/TIMESYNCHGEN:1 in PST or from the
local HMI.

Only CoarseSyncSrc can be set to IEC 60870-5-103, not FineSyncSource .
After setting up the time synchronization source, the user must check and modify the
IEC 60870-5-103 time synchronization specific settings, under
Main menu/
Configuration/Communication/Station communication/IEC60870-5-103 .
• MasterTimeDomain specifies the format of the time sent by the master. Format
can be:
•
Coordinated Universal Time ( UTC )
• Local time set in the master ( Local )
• Local time set in the master adjusted according to daylight saving time
(
Local with DST )
• TimeSyncMode specifies the time sent by the IED. The time synchronisation is
done using the following ways:
•
IEDTime : The IED sends the messages with its own time.
• LinMasTime : The IED measures the offset between its own time and the
master time, and applies the same offset for the messages sent as in the
