HMI – Human Machine Interface
A Human Machine Interface or HMI is a computer display that an operator uses to interface with the process or machine. They send and receive tag data to/from the controller via a built-in driver or an OPC server such as Kepware. Sometimes, a touchscreen is preferable. Other times, a desktop PC is fine.
