The OPC UA standard defines a modern, enhanced cybersecure, open and reliable communications architecture for industrial communications that is scalable from resource constrained sensors through to cloud enterprise systems. OPC UA extends the traditional industrial communications model with a full Service Orientated Architecture (SOA) to publish and manage device meta-information and context, eliminating repetition, simplifying system configuration and reducing maintenance overhead.
