Description

Returns the time synchronization protocol (1588, EtherCAT, GPS, etc.) being used by the selected time reference of the specified device.

Defined Values

DescriptionValue
IEEE 1588-2008A 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 BCSimilar 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-2011A 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 TABSimilar 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.
Note Note  The values defined above are not a complete list of time reference types. Other time reference types can be installed by other NI software.
