Fieldsof interest:
→
Current_data_set.offset_from_master Offset from master time source in nanoseconds as calculated
duringthe lastupdate frommaster.
Parent_data_set.grandmaster_identity Thisshould matchthelocal grandmasterclock. Ifthisdisplays
the sensor’s clock identity (derived from Ethernet hardware address) then this indicates the sensor
isnot properlysynchronizedtoa grandmaster.
Parent_data_set Variousinformationabout theselectedmaster clock.
Port_data_set.port_state This value will be SLAVE when a remote master clock is selected. See par-
ent_data_set forselectedmaster clock.
Port_data_set Local sensor PTP configuration values. Grandmaster clock needs to match these for
propertimesynchronization.
Time_properties_data_set PTPpropertiesas givenby masterclock.
Time_status_np.gm_identity Selectedgrandmasterclockidentity.
Time_status_np.gm_present True when grandmaster has been detected. This may stay true even if
grandmaster goes off-line. Use port_data_set.port_state to determine up-to-date synchronization
status. When thisis falsethen the local clock isselected.
Time_status_np.ingress_time Indicates when last PTP message was received. Units are in nanosec-
onds.
