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)
GUID-424227EC-74A1-4628-8948-C1876840ABFE v3
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.
