This chapter defines the corresponding profiles and conformance units for the OPC UA Information Modelfor POWERLINK Profilesare named groupings of conformance units. Facets are profiles that will be combined with other Profiles to define the complete functionality of an OPC UA Server or Client.The following tables specify the facets available for Serversthat implement the POWERLINK Information Modelcompanion standard, and for Clientsthat are communicating with such Servers.
Table 51defines a server facet for direct access to the POWERLINK Objectsthrough a structured NodeIdthat may be generated by user entry or by tools.
