In daily life, different technological needs may arise for each field of use. Especially for certain fields of activity, touch screens have major importance. HMI screens, which appear as a practical interface, are one of these. In its simplest sense, an HMI screen is a special software system that allows the user to communicate with machines and production facilities.
The HMI screen technology, which has a very efficient structure, offers sensitive and user-friendly features. Generally, there are main sectors where the HMI system is used. Industrial fields are among the first sectors where the HMI system is employed. The use of HMI has become an integrated feature in the automation sector with Industry 4.0.
The acronym HMI in English stands for “Human-Machine Interface.” In Romanian, HMI translates as “interfață om-mașină.” In industry, HMI is often called a touch panel, touch screen, or operator panel.
HMI technology ensures communication between users and automation systems made with systems such as PLC and PIC. These HMI screens provide a high visual experience. At the same time, through the HMI screen, you can experience advantages such as data visualization, monitoring production time, trends, and tags.
With the help of the HMI screen, you can monitor the inputs and outputs of the machine. In daily life, you can control certain devices in the home environment. For example, you can interact with and monitor the air conditioning control screen in your house. Similarly, a production line manager can obtain information about raw materials and energy.
How Do HMI Panels Work?
HMI screen systems have a special structure that allows interaction with machines and production facilities. Due to this feature, they have a wide place both in daily life and in the industrial field.
With a practical operating principle, HMI screens can be easily monitored by operators or authorized personnel. Thus, HMI controls production processes. Subsequently, HMI is responsible for transmitting the feedback received from the user to the automation system. After this stage, the data received from the automation system is displayed on the screen. The way of displaying and the structure of the data on the HMI screen vary depending on the automation system.
