Universal, bi-directional real time communication for digital twins

Year: 2026

Type: conference-paper

Abstract: The scientific work contains the solution for real-time, bi-directional communication between Digital and Real Twins in mechanical engineering. It features a three-axis XYZ axes system developed within a Model-based Systems Engineering (MBSE) environment using the RFLP V-model approach. The Real Twin is operated via a standard industrial PLC (B+R), while communication is enabled through Modelica, Named Pipes, and OPC UA (3DExperience platform). The study details the design and implementation of the communication interface, including connection types and modes. Performance is highlighted by a 10 ms turnaround time for one axis value. Potential applications span industrial (e.g. pick-and-place and 3D printing) and educational (alternatively as game-oriented demonstrator available) contexts. The project demonstrates that a complete Digital Twin Framework can be successfully integrated into a complex MBSE environment while maintaining high performance, effectively bridging the gap between physical and digital systems in mechanical engineering.
