IEC 62541-7: 2025 specifies value and structure of Profiles in the OPC Unified Architecture.
OPC UA Profiles are used to segregate features with regard to testing of OPC UA products and the nature of the testing. The scope of this document includes defining functionality that can only be tested. The definition of actual TestCases is not within the scope of this document, but the general categories of TestCases are covered by this document.
Most OPC UA applications will conform to several, but not all of the Profiles.
