“…The connection between the PLC and the software is one of them. The OPC DA is not the best option in terms of connectivity, while OPC UA (Open Platform Communication Unified Architecture), a more recent and open version, could be a solution as it is a better bridge to the data, since it was created to serve as a way to connect many types of hardware and software [20].…”

Digital twins are becoming a powerful tool to enhance industrial processes worldwide. This paper proposes a model for the creation of industrial processes' digital twins, using a steam distillation process for essential oil extraction as a case study. A grey box modeling is suggested combining a machine learning based model with physical modeling to improve the process. Real time simulation and a hybrid control strategy are used, linked to reinforcement learning and PID control, focusing on the yield increase and optimization. A creation method is elaborated to support other applications of digital twins in industrial processes in the future.

“…The connection between the PLC and Matlab is stablished using an OPC UA (Open Platform Communications Unified Architecture) connection. It was created with the aim of establishing a connection between the most diverse types of computers and through several communication protocols [5]. An application that uses OPC UA can be configured to be as complex as necessary and therefore enables and contributes to the development of IoT applications [13].…”

Introduction: Digital twins are becoming a powerful tool to enhance industrial processes worldwide. This paper proposes a model for the creation of industrial processes’ digital twins using a steam distillation process for essential oil extraction as a case study. Case Description: A grey box modeling is suggested combining a machine learning based model with physical modeling to improve the process. Real time simulation and a hybrid control strategy are used, linked to reinforcement learning and proportional integral derivative control, focusing on the yield increase and optimization. Computer Vision and Artificial Intelligence enhancements were suggested. Discussion and Evaluation: Digital twins, in combination with Artificial Intelligence can be of great help to support companies with the decision-making challenges. Furthermore, some benefits that Artificial Intelligence can bring to the process were enlightened. Computer Vision approaches were also discussed. Conclusions: A creation method is elaborated to support other applications of digital twins in industrial processes in the future. In order to apply it to different processes, generalization capabilities must be proved.

To realize the modular development of manufacturing system, this paper proposes a new structure of reconfigurable manufacturing modular structure by introducing OPC technology. According to the theory hierarchical control system, we add a new OPC standard interface layer to system structure. Then, detailed design of OPC standard interface layer is presented, including design principle, the algorithm to coding OPC server/client and prototype system. Finally, the new modular system is applied in a product line of Molded-low-voltage circuit breaker. The result shows that the new module runs stably to meet reconfiguration of manufacturing system rapidly.
