What is HMI?
HMI stands for "Human Machine Interface".
A Human-Machine Interface (HMI) is a user interface that connects a person to a machine, system, or device. This term broadly defines any device that enables a user to interact with an industrial device.
HMI involves three main human interaction functions:
- Touch (control by buttons, touch screens, keyboards, numeric keypads)
- Sight (monitoring and control on screen, supervision by light towers)
- Hearing (audible alarms, beeps)
Industrial HMI devices enable monitoring and/or control of the equipment they are connected to through a (programmable or non-programmable) controller. Their functions include:
- Settings
- Control and Command
- Monitoring and Supervision
- Historical Data Storage
- Smart Gateway
