Model-Based Interconnection of Digital and Physical Twins Using OPC UA

Abstract

The bidirectional connection of physical systems with their digital representations is a research question of recent times. This work presents a model-based connection of digital and physical twins. Therefore, we propose an approach for the bidirectional coupling of the twins using a central information point with integrated information model. Furthermore, the paper outlines use cases of visualization and remote control of a machine tool via its digital twin.
