PTP IRIG-B PRIORITY:
If two or more time sources are setup the time source with the higher priority shown in the table below is used where 1 is

The F650 is capable of receiving a time reference from several time sources in addition to its own internal clock for the
purpose of time stamping events, transient recorders and other occurrences within the relay. The accuracy of the time
stamp is based on the time reference that is used. The F650 supports an internal clock, SNTP, IRIG-B and 1588 as potential
time references.
Regarding the PTP, F650 acts as an ordinary clock, with only Sync and Pdelay_Req messages.
