CHAPTER 6: ACTUAL VALUES 6.2 STATUS
GEK-106310-AF F650 DIGITAL BAY CONTROLLER 6-35
6.2.13 IEEE 1588 precision time protocol (PTP)
Actual> Status > IRIG-B PTP 1588
This screen shows the IRIG-B and PRP status. It includes the following signaling LEDs showing the FAILURE of the SNTP and
IRIG-B and other statuses are provided.
The RTC Sync Source actual value is the time synchronizing source the relay is using at present. Possible sources are: Port
A PTP Clock, Port B PTP Clock, IRIG B, SNTP and None.
Grandmaster ID is the grandmaster Identity 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 grandmaster Identity 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.
PTP Accuracy is the estimated maximum time error at present in the Real Time Clock (RTC), considering the quality
information embedded 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.
Note:
The F650 does not support the end-to-end delay mechanism, so it is not unexpected that changing the device to which the
F650 is connected to this mode would cause the (NoPDelay) message. When PTP source clock is having "End to End clock
delay” configured, and if F650 is receiving PTP packets from this clock F650 is getting synchronized and status is showing
Synch'd (No Pdelay). Note that the relay does not allow manual overwriting of its RTC time if PTP is functional.
