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
Set the course time synchronizing source (CoarseSyncSrc) to Off
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.
