A human-machine interface (HMI) is a software application interface that helps machine operators make decisions based on real-time information. It presents process control system information to the operator using a graphic display. HMIs are typically integrated with programmable logic controllers (PLCs), programmable automation controllers (PACs) or distributed control systems (DCSs).
