Which HMI Panels to Choose in 2025? A Guide to Emerging Technologies

by Mect

In the world of industrial automation, technological evolution is progressing at a rapid pace, bringing with it new challenges and opportunities. Among the most critical components of this ecosystem, HMI (Human Machine Interface) panels represent a fundamental element for the control and monitoring of industrial processes. In 2025, choosing the right HMI panel will be crucial to optimizing efficiency, reducing costs and fully integrating with the logic of Industry 4.0.

In this article, we will explore emerging technologies and key factors to consider when choosing HMI panels. We will also present the innovative solutions proposed by Mect, an Italian company leader in the production of devices for industrial automation.

What is an HMI panel and why is it important?

An HMI panel is a human-machine interface that allows you to control and monitor industrial machinery and systems. Through a touch-screen display and a series of integrated functions, these devices allow you to manage complex processes, view real-time data and intervene quickly in the event of anomalies.

In the context of Industry 4.0, HMI panels have become increasingly intelligent and connected, integrating features such as remote control, connectivity to IT/OT systems and advanced data analytics.

What are the emerging technologies to consider?

In 2025, the technologies that will characterize HMI panels will be concentrated on three main aspects:

PLC (Programmable Logic Controller) Integration: HMI panels with integrated PLC are becoming the preferred choice for applications requiring a compact and high-performance solution. These devices combine the logic controller and the user interface in a single hardware, simplifying installation and reducing costs.
Advanced Connectivity: The ability to communicate with other devices and systems through protocols such as Modbus RTU, Modbus TCP, CANopen and Ethernet is essential for integration into industrial systems. HMI panels of the future will also need to support wireless connectivity and remote control capabilities.
Open source and customizable software: Software plays a key role in determining the flexibility and adaptability of an HMI panel. Open source solutions, such as the Mect Suite software, offer the ability to customize the system to the specific needs of the user, without being tied to expensive subscriptions or technical limitations.

How to choose the right HMI panel for your needs?

The choice of HMI panel will depend on several factors, including the size of the display, the presence of integrated inputs/outputs, connectivity features and software capabilities. Here are some tips to help you choose:

Display Size and Resolution: Your choice of monitor size (e.g. 4.3", 7", 10", 12", 15" or 19") will depend on the environment in which the panel will be used and the amount of information to be displayed. A higher resolution ensures greater readability and a better user experience.
Integrated Inputs/Outputs: If the application requires direct control of devices or sensors, it is essential to opt for an HMI panel with integrated inputs/outputs, both analog and digital.
Connectivity: Make sure your panel supports the communication protocols needed to integrate with other devices in your system.
Software: The software must be easy to use and customizable. The Mect Suite software, for example, is open source and does not require a license, offering a flexible and accessible solution.
