ABB Industrial IT Extended Automation System 800xA has been set up for centralized data collection, analysis, real-time monitoring, and advanced control. The ABB system is further expanded by cloud based advanced control and monitoring system. The state-of-the-art ABB setup includes OPC UA, providing a single entry point into a system. Each piece of equipment is automated using a dedicated PLC-station and different fieldbuses, diversifying the teaching and research benefits. The cloud based system will include an OPC UA client which allows access to ABB OPC Server using OPC UA Specifications. OPC UA scales very well in several directions. It allows OPC UA applications to run on embedded devices with very limited hardware resources, as well as on very powerful machines like mainframes. The final set up will run on the high velocity web framework Play that has been especially designed for Java and Scala. Play 2 provides native Akka support (toolkit and runtime) for Play applications enabling writing highly-distributed systems in the cloud. In addition, it follows model–view– controller (MVC) software design pattern, separating the software application into three interconnected parts: models, views, and controllers. The model manages the data, logic, and rules of the application. The monitoring and optimization algorithms are implemented in the model component. In addition, OPC UA client library will be utilized for reading and writing the data from the industrial processes. The proposed advanced teaching and process monitoring system is evaluated with test-algorithms implemented in the Spark cloud and the results are presented, analyzed, and discussed.

There is a constant challenge in process industry to reduce costs because of tight competition on the global market. On the other hand the advancement in the new technologies such as Open Platform Communications Unified Architecture (OPC UA), Industrial Ethernet, 5G, and cloud computing provide the possibility to implement cost effective Cyber-physical systems (CPS). This allows flexible, reconfigurable, scalable, interoperable business models. These trends in the process industry should be taken into account while teaching future engineers. In this article the modern process automation setup which includes three miniplants with optional 5G connectivity is described along with teaching approach for executing the students projects. Using this infrastructure students obtain knowledge with emerging industrial technology and become the actors of upcoming industrial revolution.
