Real Time Clock Synchronizing - GE T60 Instruction Manual

6.2 STATUS
These values indicate the status of the first, second, and third Ethernet links.
PATH: ACTUAL VALUES
 REAL TIME CLOCK
 SYNCHRONIZING
The 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 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
6
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.
is the present state of the port's PTP clock. The PTP clock state is:
PORT 1...3 PTP STATE
• is the port's function setting is Disabled,
DISABLED
• if enabled but no signal from an active master has been found and selected,
NO SIGNAL
• if an active master has been selected but lock is not at present established,
CALIBRATING
•
SYNCH'D (NO PDELAY)
• if synchronized.
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.
