HMI
(Human Machine Interface). In the industrial field of human-machine interaction, the user interface is (a place) where interaction between humans and machines occurs. The goal of interaction between a human and a machine at the user interface is effective operation and control of the machine, and feedback from the machine which aids the operator in making operational decisions.
Touch screens dominate the HMI market due to the cost effectiveness, capabilities and ruggedness of the hardware and software available. Embedded software platforms like Windows CE mean no hard drives or other moving parts. Some touch screens have abilities to rival most SCADA’s and are available in sizes from 4 inch to 21 inch.
HMI's are used to allow an operator to control or adjust all the functions of a piece of machinery or plant section. These might include starting, stopping, resetting, speed set points, temperature levels etc. Information and component statuses are displayed and the operator can be informed of any problems or warnings pertaining to the machine.
HMI's can be used as interfaces to link multiple hardware and communication platforms to a common platform for data to be sent to a SCADA system. The link below shows a project that represented some unique challenges for an HMI project.
