Returns the time synchronization protocol (1588, EtherCAT, GPS, etc.) being used by the selected time reference of the specified device.
Description | Value |
---|---|
IEEE 1588-2008 | A network-based time synchronization protocol (also referred to as PTP) that synchronizes devices to a single grandmaster clock. Each IEEE 1588-2008 time reference instance is associated with a single network interface on the device and can either be a slave to the network's grandmaster, or the grandmaster to a network of devices. |
IEEE 1588-2008 BC | Similar to the IEEE 1588-2008 protocol, except each instance of the IEEE 1588-2008 BC (boundary clock) time reference is associated with multiple ports, typically on a device that acts as a network switch. |
IEEE 802.1AS-2011 | A network-based time synchronization protocol similar to IEEE 1588-2008, but optimized for time-sensitive applications. IEEE 802.1AS-2011 also provides fewer configuration options and requires IEEE 802.1AS-compatible network infrastructure. Each IEEE 802.1AS-2011 time reference instance is associated with a single network interface on the device and can either be a slave to the network's grandmaster or the grandmaster to a network of devices. |
IEEE 802.1AS-2011 TAB | Similar to the IEEE 802.1AS-2011 protocol, except each IEEE 802.1AS-2011 TAB (time-aware bridge) time reference instance is associated with multiple ports, typically on a device that acts as a network switch. |
