OPC UA Profiles

OPC UA is designed to support integration of wide range of servers, from plant-floor control devices to enterprise management and operation systems. All of them are characterized by a variety of performances, execution platforms and functional capabilities. Therefore, OPC UA defines a comprehensive set of capabilities servers may implement a subset of. These subsets are referred to as Profiles, and servers may claim conformance to them. Clients can then discover the Profiles for a server, and tailor their interactions with that server based on the Profiles. Client also contains profiles which allow end user the ability to match up server profiles to client profiles, making it easier to ensure that diverse client and servers will interoperate. Servers can also discover these client profiles and could tailor their response to the client based on the client profile.
