IEEE Std 802.1AS2020 defines a gPTP domain in which system timing is consistent. A gPTP domain defines the scope of gPTP message communication, state, operations, parameters, and timescale. The Grandmaster PTP Instance is the root of a gPTP domain.
UAFX supports the following two types of gPTP domains:
Working Clock domain
Global Time domain
Working Clock domain maintains a common sense of time for use cases such as enhancements for scheduled traffic (see IEEE Std 802.1Q).
Global Time domain (e.g. wall clock) maintains a common sense of time across an industrial automation network for use cases such as sequence of events.
