Construction of a Digital Twin Framework using Free and Open-Source Software Programs

We present a novel Digital Twin Framework for a portable table-top sized temperature-controlled system constructed entirely using free and open-source software programs. By utilizing tools such as Robotic Process Automation (RPA) and a PLC program, the entire process was automated to achieve a true Digital Twin. Further, a mathematical model was constructed for the temperature-controlled system. The data from the physical model and the mathematical model was then compared and a what-if scenario was analyzed to predict and prevent a potential failure in the physical system. Additionally, a simulation model was created to visualize the results.
