Profiles are named groupings of ConformanceUnits as defined in OPC 10000-7. The term Facet in the title of a Profile indicates that this Profile is expected to be part of another larger Profile or concerns a specific aspect of OPC UA. Profiles with the term Facet in their title are expected to be combined with other Profiles to define the complete functionality of an OPC UA Server or Client.

This specification defines Facets for Servers or Clients when they plan to support OPC UA for Devices. They are described in 11.2.3 and 11.2.4.
