CHAPTER 6: ACTUAL VALUES

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, 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
is the grandmasterIdentity code being received from the present PTP grandmaster, if any. When the
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.
ACCURACY
is the estimated maximum time error at present in the RTC, considering the quality information imbedded in the
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
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
•
Synchronized
if synchronized
PTP - IRIG-B DELTA
is the time difference, measured in nanoseconds, between the fractional seconds portion of the time
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.
