This specification specifies the OPC Unified Architecture (OPC UA) Services. The Services described are the collection of abstract Remote Procedure Calls (RPC) that are implemented by OPC UA Servers and called by OPC UA Clients. All interactions between OPC UA Clients and Servers occur via these Services. The defined Services are considered abstract because no particular RPC mechanism for implementation is defined in this Part. Part 6 specifies one or more concrete mappings supported for implementation. For example, one mapping in Part 6 is to XML Web Services. In that case the Services described in this Part appear as the Web service methods in the WSDL contract.
Not all OPC UA Servers will need to implement all of the defined Services. Part 7 defines the Profiles that dictate which Services need to be implemented in order be to compliant with a particular Profile.

Part 1 presents the concepts and overview of the OPC Unified Architecture (OPC UA). Reading this document is helpful to understand the remaining Parts of this multi-part document set. Each of the other parts is briefly explained along with a suggested reading order. This Part is non-normative.<br/>T
This specification specifies the standard representation of Programs as part of the OPC Unified<br/>Architecture and its defined information model. This includes the description of the NodeClasses,<br/>standard Properties, Methods and Events and associated behaviour and information for Programs.<br/
This specification describes the OPC Unified Architecture security model. It describes the security threats of the physical, hardware, and software environments in which UA is expected to run. It describes how UA relies upon other standards for security. It gives an overview of the security features
This specification defines the Information Model of the OPC Unified Architecture. The Information Model describes standardised Nodes of a serverβs AddressSpace. These Nodes are standardised types as well as standardised instances used for diagnostics or as entry points to server specific Nodes. Thus
This specification describes the OPC UA AddressSpace and its Objects, define the concepts of the AddressSpace. Clause 5 defines the NodeClasses of the AddressSpace representing the AddressSpace concepts. Standard ReferenceTypes, DataTypes and EventTypes are defined in Clauses 6-8.<br/>The informativ
