6: MASTER - the PTP is behaving as a master
7: PASSIVE - the PTP will not send any messages except for peer delay, signalling or management messages
8: UNCALIBRATED - the PTP is in a transient state. One or more master ports have been detected in the domain. The
appropriate master port has been selected, and the local port is preparing to synchronize to the selected
master port.
9: SLAVE - the PTP is synchronizing or synchronized to a master
PTP Clock

-
NEVER
PTP parameter.
Diagnostic parameter giving the current value of the PTP clock to 1 second accuracy. Note this is not intended to represent the
actual date and time.
PTP Offset

Monitor::Communications::PTP
Parameters::Base Comms::PTP
0 ns
-2000000000 to
2000000000
NEVER
PTP parameter.
Diagnostic parameter giving the average offset in nanoseconds between the PTP clock and the master clock.
PTP Locked
1688
Monitor::Communications::PTP
Parameters::Base Comms::PTP
FALSE
FALSE
TRUE
NEVER
PTP parameter.
Diagnostic parameter indicating when the inverter is a slave that the PTP clock has synchronised to a master clock determined by
parameter 1685 PTP Locked Threshold. If the inverter is a master then this parameter will be set to TRUE.
