Time Sync view status

Indicates if Time Synchronization is enabled or disabled on the controller or in the offline project file.

The current system time in Universal Coordinated Time (UTC). The time does not include time zone or daylight savings time offsets.

The unique identifier for the grandmaster clock and local clock.

The measure of the traceability of the grandmaster clock and local clock to primary reference sources. The measure of the traceability is pre-defined by the hardware manufacturer. Values are defined from 0 through 255 with zero as the best clock. Clocks with Class values below 128 may only be master clocks.

Specifies whether the local clock is synchronized or not synchronized with the grandmaster reference clock. A clock is synchronized if it has one port in the slave state and is receiving updates from the time master.

The amount of deviation between the local clock and the grandmaster in nanoseconds, updated every sync interval.

The expected absolute accuracy of the grandmaster clock and local clock relative to the clock epoch of January 1, 1970.

The accuracy is specified as an enumerated logarithmic scale, where:

A measure of the inherent stability properties of the grandmaster clock and local clock. The value is represented in offset scaled log units. The lower the variance, the more accurate the clock.

The time source of the grandmaster clock and local clock. The available values include Atomic clock, GPS, Radio, PTP, NTP, HAND set, Other, and Oscillator.

The relative first priority of the grandmaster clock and local clock to other clocks in the system. The priority range is 0 - 255. The highest priority is 0. The default is 128.

The relative second priority of the grandmaster clock and local clock to other clocks in the system. The priority range is 0 - 255. The highest priority is 0. The default is 128.

The state of the controllers port. The available values are:

Initializing, Faulty, Disabled, Listening, PreMaster, Master, Passive, Uncalibrated, Slave, or None.

Devices that have multiple ports, such as 1756-EN2T modules, have independent states for each port.

The current state of the Ethernet port. The available values are: Initializing, Faulty, Disabled, Listening, PreMaster, Master, Passive, Uncalibrated, Slave, or None.

Devices that have multiple ports (such as 1756-EN2T modules) have independent states for each port.

The name of the user who enabled time synchronization.

The location of the user who enabled time synchronization.

The time of the grandmaster clock.

The IP address of the controller or device that is currently the grandmaster clock.

The physical location of the grandmaster clock.

The 6-digit identifier that indicates whether the port is following IEEE 1588 PTP without redundancy (00-21-6C-00-01-00) or also supports PRP for redundancy (00-15-4E-00-01-50).

The manufacturer of the grandmaster clock.

The model number of the grandmaster clock.

The serial number of the grandmaster clock.

The hardware revision of the grandmaster clock.

The firmware revision of the grandmaster clock.

The software revision of the grandmaster clock.

The physical layer of the port, such as Backplane or Ethernet.

The port protocol of the grandmaster clock:

The port number where the grandmaster clock exists.
