To setup a PTP network with no obvious Grand Master, you simply connect the IEDs
to one network and configure PTP to be “on” on all IEDs. On one IED, the one from
which you want to set the time in the station, you set the Priority2 to 127, instead of
default 128. Now, this IED has higher priority than the rest of the IEDs and will
thereby act as “Grand Master”.
PTP is not set from TIMESYNCGEN:1General , as SNTP is. Instead PTP is set via a
parameter of each Access Point.

22.2.1 Functionality
M12006-6 v7
Use the six different groups of settings to optimize the IED operation for different
power system conditions. Creating and switching between fine-tuned setting sets,
either from the local HMI or configurable binary inputs, results in a highly adaptable
IED that can be applied to a variety of power system scenarios.
