For the purposes of this document, the terms and definitions given in OPC 10000-80, OPC 10000-100, IEEE Std 8022014, IEEE Std 802.1AS2020, IEEE Std 802.1AB2016, IEEE Std 802.1Q2018, IEEE Std 1588, as well as the following apply.
All used terms are italicized in this document as described in OPC 100001.
set of Bridge functionalities necessary for acting as a traffic relay station in a network
implementation of an end station
synchronized time in a network clock derived from a gPTP domain that is traceable to International Atomic Time
material element or assembly composed of one or more End Station Components and zero or more Bridge Components
OPC UA Application that includes UAFX functionality
IAstation supporting the OPC UA FX communication and application layer
synchronized time in a network clock derived from a gPTP domain that is traceable to an arbitrary timescale or to the PTP timescale
Note 1 to entry In general, the Working Clock time is traceable to an arbitrary timescale; however, the Working Clock time can be correlated to a recognized timing standard.

Block diagrams are used in figures throughout this document to illustrate groupings of functionality. The blocks in these diagrams represent abstract concepts and are not meant to imply a particular implementation.
In this specification, the name of a type without the inclusion of “Type” indicates an instance of the type. For example, the following phrase, “an instance of ConnectionConfigurationSetType,” can be replaced with “a ConnectionConfigurationSet”. The phrase “instances of ConnectionEndpointType” can be replaced with “ConnectionEndpoints”.
