6-8 G30 Generator Protection System GE Multilin6.2 STATUS 6 ACTUAL VALUES6These values indicate the status of the first, second, and third Ethernet links.6.2.13 REAL TIME CLOCK SYNCHRONIZINGPATH: ACTUAL VALUES STATUS REAL TIME CLOCK SYNCHRONIZINGThe RTC Sync Source actual value is the time synchronizing source the relay is using at present. Possible sources are:Port 1 PTP Clock, Port 2 PTP Clock, Port 3 PTP Clock, IRIG-B, SNTP, and None.The Grandmaster ID is the grandmasterIdentity code being received from the present PTP grandmaster, if any. When therelay is not using any PTP grandmaster, this actual value is zero. The grandmasterIdentity code is specified by PTP to beglobally unique, so one can always know which clock is grandmaster in a system with multiple grandmaster-capable clocks.Accuracy is the estimated maximum time error at present in the RTC, considering the quality information imbedded in thereceived time signal. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more, orthat the error cannot be estimated.PORT 1…3 PTP STATE is the present state of the port’s PTP clock. The PTP clock state is:• DISABLED is the port’s function setting is Disabled,• NO SIGNAL if enabled but no signal from an active master has been found and selected,• CALIBRATING if an active master has been selected but lock is not at present established,• SYNCH’D (NO PDELAY) if the port is synchronized, but the peer delay mechanism is non-operational, and• SYNCHRONIZED if synchronized.PTP-— IRIG-B DELTA is the time difference, measured in nanoseconds, between the fractional seconds portion of the timebeing received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared toIRIG-B time.
