A configuration tool for MQTT based OPC UA PubSub

Contemporary manufacturing enterprises are challenged by fast-growing requirements for flexible and effective production, and also rapidly changing demands of market. One goal of industrial system information integration is to use appropriate flexible and scalable communication technologies to satisfy the requirements of industrial devices and systems. To achieve these requirements, technologies and paradigms such as the Internet of Things (IoT), Reconfigurable Manufacturing System (RMS) and Industrie 4.0, etc., are proposed and developed in recent years. Among these solutions, Open Platform Communication Unified Architecture (OPC UA) is one of the most widely used specifications for industrial system and device communication. Now the specification is extended by adding a new communication architecture named PubSub to provide asynchronous information exchange capability. After a brief review of industrial Information and Communication Technologies (ICTs) and existing solutions for the manufacturing system, an MQTT based OPC UA PubSub implementation and its configuration tool are introduced in this paper. Our OPC UA PubSub implementation can be easily integrated into other C/C++ OPC UA projects.
