The manufacturing industry is undergoing a rapid trend toward digitalization. As a result, information and manufacturing systems are integrated into today's industrial systems. In this context, damage caused by cyber-attacks has become apparent, and cyber-attacks on factories are on the rise domestically and internationally. As a result, there is an increasing need for cybersecurity measures and education in the manufacturing industry and factories.
The industrial automation industry has begun to develop designs with virtual commissioning based on digital twin models, and all of these development tasks are increasingly conducted in virtual space. However, no security education materials based on these technologies utilize cyber-physical space (CPS), which is free from time and space.
Therefore, in this study, we create a model that moves in a virtual space similar to that of the actual experimental equipment. These models can be configured as a simple digital twin of the experimental equipment that also exists in real space and can be linked to experiments and practical training using actual equipment as before. An environment will be created in which these models can be operated and exercised in a virtual space.
The models can control pressure and water level at the same time with control exercise equipment at NIT KOSEN Yonago College. The entire plant, including the pressure and water tank, will be modeled on a process simulator (Siemens SIMIT), and the controller (PLC) will be virtualized.
When experiments and practical training are conducted in a distance education environment using digital twin technology, the same educational effects can be expected as with conventional investigations and practical training using actual equipment. In addition, by combining experiments and practical training using existing equipment with extensive use of modeling and the distance education environment, it is possible to expand into large-scale, complex, and diverse fields that were previously unfeasible due to many constraints (space, cost, human resources, etc.), and to safely conduct practical cyber security exercises The new system also allows for safe and practical cyber security exercises to be undertaken.
