 OPC UA protocol allows companies or organizations to standardize their data for an OPC UA information model. It is possible to generate standardized interfaces for the OPC UA servers, so OPC UA clients only need to know the information defined in that standard and not taking into account information not relevant.
 
-This standardized interface is called companion specification. There are already many organizations or groups of companies which have already standardized some OPC UA information models for some industries, but a user can also create their own companion specifications.
