The Capabilities and Advantages of Human Machine Interface

A Human Machine Interface, referred to as HMI in the tech world, is simply a user interface that connects a person to a machine, system or device. In the most simple of terms, HMI is a technology that allows human beings and machines to interact. The possibilities of this technology are extensive, and as a result it’s used in a variety of different industries, ranging from entertainment through to medicine.

Human Machine Interface technology helps to assimilate humans into complex tech systems and can include keyboards, speech recognition, motion sensors and other devices to track certain types of information and extract data.

Below, HYDAC details the various capabilities and benefits of the Human Machine Interface.


Perhaps one of the most attractive factors of Human Machine Interface technology is its user-friendly and simple graphical interface. The graphical interface used in combination with HMI identifies and troubleshoots through colour coding and fast recognition.

These easy identification tools mean that HMI can cut down costs of manufacturing by converting hardware into software, allowing direct human-to-computer interaction, and removing the need for other devices traditionally used in combination with computers, like a mouse or keyboard. Through HMI, the interaction between humans and the device works in real-time and you’re able to easily simulate finger touching sensors to update and carry out applications accordingly.

Flexibility Over Controls

Human Machine Interface technology allows for a flexible customisation of your interface. HMI systems can track, monitor and support some of the most complex systems in simple steps, which means you have the opportunity to run multiple screens at once. When working alongside tech manufacturers, you have the chance to develop a HMI that’s personalised for your specific tasks and outcomes.

HMI technology comes with different features, with capabilities for simple remote access to control specific applications. HMI allows for you to execute several tasks at once, meaning you can control outcomes while tracking information and drawing conclusions at the same time. HMI technology is set up with ‘recipe functions’, meaning a single push of a button can bring about value changes, updates, modifications, and more.

Data Connection and Performance

HMI technology is usually used through a connection to PLCs (Programmable Logic Controllers) in order to easily extract real-time data. By connecting to a PLC device, data is still connected without the HMI needing to be on or in use. This minimises the possibility of losing data or information during a network connection loss, making it a possibility to use HMI in poor connection environments. Data will also not be lost when updating to the newest software.

Thanks to the consistent proliferation of the current technology climate, Human Machine Interface technologies perform at an impressive standard. Some HMI systems have been known to store up to 10 years of raw and easily accessible data. Data can be accessed quickly and effectively through these systems, contributing to efficient processes.
