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
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.

The PTP VLAN tag must have the same value in station clock and in the IED. The
default value is set to 0.
The PTP VLAN tag does not need to be the same on all access points in one IED. It
is possible to mix as long as they are the same for all devices on each subnet.
