4 About OPC UA

The OPC United Architecture is a machine to machine communication protocol for

industrial automation, providing a platform independent, service-oriented architecture

that integrates all the functionality of the OPC Classic specifications into one extensible

framework.

This multi-layered approach accomplishes the original design specifications goals of:

1. Functional equivalence: all COM OPC Classic specifications are mapped to UA

2. Platform independence: from an embedded micro-controller to cloud-based

infrastructure

3. Secure: encryption, authentication, and auditing

4. Extensible: ability to add new features without affecting existing applications

5. Comprehensive information modelling: for defining complex information

Detailed information about the OPC United Architecture is available at

https://opcfoundation.org/
