A human-machine interface, or HMI, is a device that allows an operator to interact with a machine. Using inputs, outputs, industrial networks, operating systems and specialized software, the HMI can communicate with any production system.
Modern HMIs have advanced multi-touch displays that operators can use to closely monitor production, adapt to production demands, and quickly respond to equipment fault or failure. Today, sophisticated industrial networks even allow operators to manage process remotely, from central control rooms or even smartphones and tablets.
HMIs are can applied to any industrial application, but they are particularly useful in process industries like oil and gas, mining, wastewater treatment and others due to the on-demand information and improved diagnostics they can provide.
