OPC Unified Architecture (OPC UA)

The OPC next generation standard

OPC Unified Architecture (OPC UA) is the data exchange standard for a manufacturer and platform-independent horizontal and vertical industrial communication. As IEC62541 standard, it provides security by design and the extension with information models and thus goes far beyond a pure data exchange protocol. OPC UA can be integrated with 15kB in smallest sensors, but is also in the controller, HMI up to the MES level and IT cloud. OPC UA has arisen in the automation industry - but the services are industry-neutral.

The SAP Plant Connectivity (SAP PCo) supports OPC UA.
