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 that are specified in other parts of the OPC UA specification. It references services, mappings, and profiles that are specified normatively in other parts of this multi-part specification. This part of the specification is informative rather than normative. Any seeming ambiguity between this part and one of the normative parts does not remove or reduce the requirement specified in the normative part.
This Part 2 is directed to readers who will develop OPC UA client or server applications or implement the OPC UA services layer.

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
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 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 Ser
