OPC UA PubSub Implementation and Configuration

摘要

OPC UA (Open Platform Communication Unified Architecture) is one of the most widely used specifications for industrial system communication. In the context of increasingly complex technologies of the Industrial Internet of Things (IIoT) and requirements for interoperability of the Industrie 4.0, the specification is extended by adding a new communication architecture named PubSub to provide asynchronous information exchange capability. This paper introduces our OPC UA PubSub and MQTT based configuration tool, and a PubSub implementation that can be easily integrated into other C/C++ OPC UA projects.
