This screen visualizes gas information for a meter, and monitors data like tank levels, oil volumes, etc. HMI display from Pioneer Natural Resources. This HMI from SugarCreek’s food-engineering plant shows their wastewater treatment plant system and allows them to run control operations. This HMI screen built for Mountain Regional Water District shows an overview of the district's system. This screen shows work orders (top half of the screen), KPIs (bottom left), and OEE (bottom right). HMI for Applied Tech Systems (ATS) that displays and monitors work orders for an airplane-production floor at a university facility. HMIs come in a variety of forms, from built-in screens on machines, to computer monitors, to tablets, but regardless of their format or which term you use to refer to them, their purpose is to provide insight into mechanical performance and progress. Similar to how you would interact with your air-conditioning system to check and control the temperature in your house, a plant-floor operator might use an HMI to check and control the temperature of an industrial water tank, or to see if a certain pump in the facility is currently running. Track production time, trends, and tags.In industrial settings, HMIs can be used to: HMI and Graphical User Interface (GUI) are similar but not synonymous: GUIs are often leveraged within HMIs for visualization capabilities. While the term can technically be applied to any screen that allows a user to interact with a device, HMI is most commonly used in the context of an industrial process.Īlthough HMI is the most common term for this technology, it is sometimes referred to as Man-Machine Interface (MMI), Operator Interface Terminal (OIT), Local Operator Interface (LOI), or Operator Terminal (OT).
