The Human-Machine Interface (HMI) is a great tool for manufacturers to improve their manufacturing processes. They provide a centralized location for production data and machine interaction. The evolution from batch processing in the 1950s to their software capabilities today make HMIs a useful tool for operators, engineers and other professionals working on the production line. export. Read more about HMIs and how they will benefit your production line below.

Industrial control systems continue to evolve, and in today’s world the tasks that an operator needs to complete can change frequently. To handle this complexity, you need flexibility and usability in your controls. That’s the benefit of an HMI. With a zenon-based HMI, you can easily interface with machines and get operational data from across your devices and facilities.

What is an HMI monitor?

Before learning about HMI screens, let’s take a look at the concept of HMI.

What Is An Hmi Monitor?

HMI stands for Human Machine Interface, which is defined as a feature or component of a particular device or software application that allows humans to engage and interact with machines. hook. Exactly HMI refers to the control panel or display used to control the machines.

HMIs used in industry are mainly monitors or touch screens. In industrial environments, HMIs come in many forms, be it simple displays mounted on factory machinery or advanced touch screens, multi-touch support panels, push buttons, machines. computer with keyboard, mobile device or tablet.

Thus, the HMI screen is the screen that connects the user to the industrial machine, system or device. Factory operators use them to control and automate their machines and production lines.

HMI screen configuration

An HMI screen is made up of 3 main parts: hardware, software and communication.

  • Hardware: including screen, body, frame, electronic devices, etc. There are also keys, chip (CPU), program memory such as ROM, RAM, EPROM/Flash, etc.
  • Software: includes functions and commands, development software, HMI building tools, connection tools, loading and debugging tools, simulation tools, etc.
  • Communication: includes protocols such as Mobus, CANbus, PPI, MPI, Profibus, etc. RS232, RS485, Ethernet and USB communication ports.

Software and hardware allow the operator to monitor and control the status of the process, or modify the settings to change control targets and manually override automated control operations in the process. emergency situation.

How does the HMI display work?

HMI displays work by connecting an operator to a system, device or machine through a display or control panel.

HMIs are often used in conjunction with PLCs (Programmable Logic Controllers) to monitor and control processes in an automated system as well as allow the user to communicate with the PLC through the interface. graphical interface (usually a touch screen).

This interface allows giving commands, and receiving and translating response data from the PLC, which is then presented visually on the screen. This provides the operator with much needed flexibility and control over a given system.

Instead of simply displaying data that is difficult for the operator to analyze quickly, HMI displays allow information to be presented visually, often in the form of graphs, illustrations, or photographs, helping to evaluate the data. from different machines, processes and locations quickly and easily.

A good example of a popular HMI display is a tablet or smartphone, which has a built-in touchscreen that allows the user to interact directly with the machine’s program.

The HMI display also allows the control engineer or operator to configure setpoints or control algorithms and parameters in the controller. They also display process status information, historical information, reports, and other information to operators, administrators, managers, business partners, and other authorized users.

Operators and engineers use the HMI to monitor and configure setpoints, control algorithms, send commands, adjust, and set parameters in the controller.

#1. #first. Enhanced visibility: High-performance HMI displays provide enhanced visibility into system activities at all times. They allow the operator to see how the equipment or facility is performing from a single dashboard, even remotely viewing it. These capabilities help improve productivity over time and respond to alerts faster.

#2. Increased efficiency: Since the HMI monitor provides constant access to real-time data, it can be used to monitor production and adjust as needed. Data visualization, especially when combined with data analytics technologies, can help users make changes that can improve operational efficiency.


Vì màn hình HMI cung cấp khả năng truy cập liên tục vào dữ liệu thời gian thực nên nó có thể được sử dụng để giám sát quá trình sản xuất và điều chỉnh khi cần. Trực quan hóa dữ liệu, đặc biệt là khi được kết hợp với các công nghệ phân tích dữ liệu, có thể giúp người dùng thực hiện các thay đổi nhằm cải thiện hiệu quả hoạt động.

#3. Reduce downtime: With alerts on the central control panel, operators can respond to problems faster, reducing production system downtime. Viewing and analyzing equipment performance data also helps identify signs of future machine problems and address them before they become problems, avoiding damage.

#4. Improved usability: The HMI display makes it easier for users to view and understand data and control the device. Data is presented in the form of graphs, charts, and other visualizations, making it easy for users to interpret the data quickly.


HMI . screen application

HMI technology is used by most industrial organizations as well as many other companies to interact with machines and optimize their industrial processes.

HMI displays are used in a wide variety of industries including manufacturing plants, vending machines, food and beverage, pharmaceutical and utilities, and more.

Along with PLCs, HMI screens are considered the backbone of production lines in these industries. Their integration into any production system can greatly improve operational productivity by enabling monitoring control and data collection throughout the system or changing available parameters depending on the needs of the system. at operator’s choice.
