A human-machine interface (HMI) is the user interface that connects an operator to the controller for an industrial system.

            Human-machine interface (HMI) – also known as User Interface (UI), Operator Interface Terminal (OIT) or Man Machine Interface (MMI) – encompasses hardware and software solutions for information exchange and communication between systems/machines and a human operator. HMIs enable control, management and/or visualization of device processes and can range from simple inputs on a touch display to control panels for highly complex industrial automation systems
