The HMI is the Human Machine Interface. It basically allows the operators to interface or communicate with the system that they are overseeing. The HMI provides a pictorial overview of the status of the mechanical system as well as its operation’s direct control. The graphical screens of the HMI can be so programmed as to allow the operator to view all-important statuses as well as control information. The HMIs make use of pictures, sounds, icons and solid colors in order to visually exemplify the various operating conditions. Many HMIs even deploy the advanced touch screen technology to improve the user’s interaction with the elements displayed on-screen.
