Time Sync Status view parameters

Displays whether the CIP Sync Time Synchronization is enabled or disabled on the device.

Displays the current system time in units of microseconds.

Displays clock property information for the grandmaster clock. The grandmaster clock is the most precise clock source in the network.

Displays the unique identifier for the grand master clock. The format depends on the network protocol. Ethernet encodes the MAC address into the identifier while DeviceNet and ControlNet encode the Vendor ID and serial number.

Displays a measure of the quality of the grand master clock. Values are defined from 0 through 255 with zero (0) as the best clock.

Indicates the expected absolute accuracy of the grand master clock relative to CIP Sync Time Synchronization epoch (31 December, 1969 23:59:51.99918 UTC). The accuracy is specified as a graduated scale starting at 25 nanoseconds and ending at greater than 10 seconds or unknown. For example, a GPS time source accuracy is approximately 250 nanoseconds. A HAND set clock accuracy is typically less than 10 seconds. A lower accuracy value indicates a better clock.

Displays the measure of inherent stability properties of the grandmaster clock. The value is represented in offset scaled log units. A lower variance indicates a better clock.

Displays the time source of the clock. Available values:

Display the relative priority of the grandmaster clock to other clocks in the system. The value is between 0 and 255. The highest priority is zero (0).

Displays clock property information for the local clock.

Displays the unique identifier for the local clock. The format depends on the network protocol. Ethernet encodes the MAC address into the identifier while DeviceNet and ControlNet encode the Vendor ID and serial number.

Displays the measure of quality of the local clock. Values are defined from 0 through 255 with zero (0) as the best clock.

Indicates the expected absolute accuracy of the local clock relative to CIP Sync Time Synchronization epoch (31 December, 1969 23:59:51.99918 UTC). The accuracy is specified as a graduated scale starting at 25 nanoseconds and ending at greater than 10 seconds or unknown. For example, a GPS time source has an accuracy of approximately 250 nanoseconds. A HAND set clock typically has an accuracy of less than 10 seconds. A lower accuracy value indicates a better clock.

Displays the measure of inherent stability properties of the local clock. The value is represented in offset scaled log units. A lower the variance indicates a better clock.

Displays the time source of the local clock. Available values:

Displays whether the local clock is synchronized or asynchronized with the grandmaster clock reference clock. A clock is synchronized if one port is in the slave state and is receiving updates from the time master. Available values:

Displays the offset value between the local clock and the master clock.
