What is Human Machine Interface?

What is Human Machine Interface?

Definition(s): The hardware or software through which an operator interacts with a controller. An HMI can range from a physical control panel with buttons and indicator lights to an industrial PC with a color graphics display running dedicated HMI software.

What HMI trends?

The trend in HMI design today is to use large, bright and colorful LCDs. These displays offer a wealth of information never accessible before, whether as part of a computer workstation or an embedded IoT controller.

What are human machine interfaces and why are they becoming more important?

HMIs are used to optimize an industrial process by digitizing and centralizing data for a viewer. By leveraging HMI, operators can see important information displayed in graphs, charts, or digital dashboards, view and manage alarms, and connect with SCADA and MES systems, all through one console.

What are the features of HMI?

10 Essential features to implement secure distributed HMI systems

  • Typical Requirements and Application Areas.
  • Features set.
  • Tag-Level Security.
  • Integrating Multiple User Security Models.
  • Security and Web Gateways.
  • Smart Clients.
  • Concurrent Engineering and Hot Start.
  • Built-in Redundancy in multiple levels.

What is the purpose of HMI?

HMIs allow operators to start and stop cycles, adjust set points, and perform other functions required to adjust and interact with a control process. Because the HMI is software based, they replace physical wires and controls with software parameters, allowing them to be adapted and adjusted very easily.

Where is HMI used?

Industries such as energy, water, wastewater, buildings and transportation may also use HMIs. Roles such as system integrators, operators and engineers, especially process control system engineers, frequently use HMIs. These professionals may use HMIs to control machines, vehicles, plants or buildings.

What are the applications of HMI?

HMIs can be found in multiple locations such as portable handheld devices, on machines, centralized control rooms, as well as factory floor machine and process control. Applications include industrial and building automation, digital signage, vending machine, medical, automotive, and appliances.

What is the advantage of human to machine interaction?

Though there are a couple of advantages of using the Human Machine Interface technology, user-friendliness is the most attractive. This is because they are integrated with simple graphical interfaces to help in identifying and troubleshooting through instant recognition and automatic color coding.
