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)
• SNTP
• IRIG-B
• PPS
CoarseSyncSrc which can have the following values:
• Off
• SPA
• LON
• DNP
• IEC 60870-5-103
The function input to be used for minute-pulse synchronization is called
BININPUT. For a description of the BININPUT settings, see the Technical
Manual.
The system time can be set manually, either via the local HMI or via any of the
communication ports. The time synchronization fine tunes the clock (seconds and
milliseconds).
The parameter SyncMaster defines if the IED is a master, or not a master for time
synchronization within a Substation Automation System, for IEDs connected in a
communication network (IEC 61850-8-1). The SyncMaster can have the following
values:
• Off
• SNTP -Server
