STATUS
These values indicate the status of the first, second, and third Ethernet links.

6.3.14 Real time clock synchronizing

ACTUAL VALUES  STATUS  REAL TIME CLOCK SYNCHRONIZING
 REAL TIME CLOCK
 SYNCHRONIZING
actual value is the time synchronizing source the relay is using at present. Possible sources are: Port 1
RTC SYNC SOURCE
PTP Clock, Port 2 PTP Clock, Port 3 PTP Clock, IRIG-B, Other, and None, where "Other" means any less precise source (SNTP,
IEC 103, IEC 104, or DNP). An actual value displays when the relay includes the IEEE 1588 software option.
The
GRANDMASTER ID
relay is not using any PTP grandmaster, this actual value is zero. The grandmasterIdentity code is specified by PTP to be
globally unique, so one can always know which clock is grandmaster in a system with multiple grandmaster-capable

clocks.
is the estimated maximum time error at present in the RTC, considering the quality information imbedded in the
ACCURACY
received time signal. The value 999,999,999 indicates that the magnitude of the estimated error is one second or more, or
that the error cannot be estimated.
PORT 1...3 PTP STATE
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
Synchronized if synchronized
is the time difference, measured in nanoseconds, between the fractional seconds portion of the time
PTP - IRIG-B DELTA
being received via PTP and that being received via IRIG-B. A positive value indicates that PTP time is fast compared to IRIG-
B time.
