OPC UA Communication Standard

Smar also has an application called Concentrator that allows communication with the entire automation system, through the OPC UA standard.

The OPC UA standard was released in 2008. The OPC Unified Archicture (UA) is an open communication standard, with a platform-independent service-oriented architecture that integrates all the functionality of the individual OPC Classic specifications into an extensible framework.

Its main features are security and encryption, the fact that it is fully object-oriented and also has information models that allow the OPC UA standard to be modeled for different applications.

The Concentrator can connect to any OPC DA server and from there make the data available in the OPC UA standard.
