6.2 STATUS 6 ACTUAL VALUES
6
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, and
•
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.

IEC 61850 GOOSE UINTEGERS
The L90 Line Current Differential System is provided with optional IEC 61850 communications capability.
This feature is specified as a software option at the time of ordering. Refer to the
Ordering section of chap-
ter 2 for additional details.
The IEC 61850 GGIO5 integer input data points are displayed in this menu. The GGIO5 integer data values are received
via IEC 61850 GOOSE messages sent from other devices.
