The document provides a history and overview of OPC (OLE for Process Control) and OPC UA (OPC Unified Architecture). It outlines the key releases and specifications developed by the OPC Foundation over time, including the original OPC Classic specifications in the 1990s, the release of the OPC UA specification in 2006, and ongoing development of additional specifications. It also summarizes the core aspects of the OPC UA architecture such as its information model framework, communication model, and security features.

33. Who: Federal Office for Information Security (German Government BSI)
Why: Because of relevance of OPC UA for German Industry
What: Security Evaluation of OPC-UA – finalized March 2016
- Analysis of specification
- Analysis of Reference Implementation
 The specification analysis has revealed no systematic errors, and has thus
shown that OPC UA, in contrast to many other industrial protocols, provides a
high level of security.
