Iec 61850 Goose Integers - GE L90 Instruction Manual

6 ACTUAL VALUES
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, how long the relay has had to lock to the time source, and in the case of time signal interruptions, the
length of the interruption. 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
• if the port is synchronized, but the peer delay mechanism is non-operational, and
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. The value 999,999,999 indicates that the difference is not being measured due to one or both of the time sig-
nals being absent or disabled.

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.
