Explanation: A HMI (Human Machine Interface) is a graphical interface that allows operators to interact with the industrial process. It provides a visual representation of the process, displays real-time process data, and allows operators to control and adjust the process. HMI can be either a physical panel or a software-based interface and it is used to improve the efficiency and safety of the industrial process by providing operators with all the necessary information and control options.
