Digital Twin proposal using the Matlab-Stateflow model and Docker containers

The core of the contribution is a proposal for the implementation of Digital Twin (DT) of a real production line in a laboratory environment. The source of data is the physical production line – Festo AFB factory. The functional logic of the physical Programmable Logic Controllers (PLC) is simulated as a block within a Stateflow object in MATLAB. As a virtualization hosting system, an open-source containerization platform, known as DOCKER, including the simulation of communication infrastructure, is proposed. Thanks to connection between real and virtual process, it is possible to transfer of real process values online to virtualized DT. In addition, the proposed DT can be connected to the existing Manufacturing Execution System (MES) and implement control of the entire line in a virtualized form. The advantage of such a solution is the possibility of using the data of the MES data historian server for the simulation of fault states within the DT environment.
