We want to build a city simulator OT(Operational Technology) system with two railways and create two kinds of HMI software (Engineer monitoring HMI and the Lecturer training HMI) to control the system. We also want to use this system to demo different kinds of PLC OT-Cyber attack by implementing the related attack simulation function.
