In many cases, when we want to build a new model the first step is to implement a Virtual model of the system and verify how it works by looking at the response of the system and the critical issues. This allows us to save on time and costs for modelling new prototypes and look at first eventual problems in the system before implementation. This project will show how a Virtual Model can interact with a real PLC. The idea is to create a virtual model equal to the existing machine and show the difference of interaction with the real and virtual PLC i.e.
