4.1 General ToC Previous Next

The OPC Unified architecture multipart standard describes a number of Services and a variety of information models. These Services and information models can be referred to as features of a Server or Client. Servers and Clients need to be able to describe which features they support and wish to have certified. This document provides a grouping of these features. The individual features are grouped into ConformanceUnits which are further grouped into Profiles. Figure 1 provides an overview of the interactions between Profiles, ConformanceUnits and TestCases. The large arrows indicate the components that are used to construct the parent. For example a Profile is constructed from Profiles and ConformanceUnits. The figure also illustrates a feature of the OPC UA Compliance Test Tool (CTT), in that it will test if a requested Profile passes all ConformanceUnits. It will also test all other ConformanceUnits and report any other Profiles that pass conformance testing. The individual TestCases are defined in separate documents see Compliance Part 8 UA Server and Compliance Part 9 UA Client. The TestCases are related back to the appropriate ConformanceUnits defined in this standard. This relationship is also displayed by the OPC UA Compliance Test Tool.
