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.
