Industrial control systems continue to advance and in today’s world, operator tasks can change frequently. To manage this complexity, you need flexibility and usability in the controls. This is the advantage of the HMI. With a zenon-based HMI, you can easily communicate with machines and get data between equipment and facilities.
HMI stands for human-machine interface and refers to a panel that allows a user to communicate with a machine, software or system. Technically, it can refer to any screen that is used to interact with a computer, but it is normally used for those in industrial environments. HMIs display data in real time and allow the user to control machines with a graphical user interface.
Let’s take the example of a car. It is a complex machine. The driver can control the engine, steering, lights, etc. It is not necessary to interact directly with each of them to control them and obtain information on their operation. The speed is displayed on the speedometer. You can control the audio, lights and air conditioning with wheels and buttons or with a touch screen. To control the engine, use the accelerator and to turn, the steering wheel. These controls and instruments are like the HMI of the car. Now imagine that you could control all the elements of your vehicle and obtain detailed information on its operation from a single screen. If it could, your car’s dashboard would be even more like an HMI.
In an industrial environment an HMI can take different forms. It can be a standalone screen, a panel attached to another computer, or a tablet. It doesn’t matter what they look like; its main use is to allow users to view operational data and control machines. Operators can use an HMI to eg. For example, see which conveyor belts are on or adjust the temperature of an industrial water tank.
What is an HMI? The advanced HMI allows you to easily communicate with machines and view operational data for all equipment.
The HMI is used in a wide range of industries. It is common in the manufacture of different products, from cars to food and beverages to medicines. Industries such as energy, water, wastewater, buildings, and transportation can also use HMI. Positions such as system integrators, operators and engineers, and especially process control system engineers, frequently use HMIs to control machines, vehicles, plants or buildings.
