HMI File – What is .hmi file and how to open it?

HMI File Format

An Human Machine Interface (HMI) file is a type of audio file used in HMI systems, which are the interface between humans and industrial equipment. HMI files typically contain voice prompts, alarms, and other audio cues used to communicate with operators. The HMI file format is a proprietary format developed by various HMI software vendors.

HMI files are typically small in size, making them suitable for use in embedded systems. They are also designed to be easily played back on a variety of devices, including HMIs, PLCs, and PCs. HMI files can be created using a variety of HMI software tools, and they can be imported and exported to other audio formats, such as WAV and MP3.

HMI File Structure

HMI files are typically structured as follows:

• Header: The header contains information about the file, such as the file size, the number of channels, and the sample rate.
• Data: The data section contains the audio data. The audio data is typically encoded using a lossless compression algorithm, such as PCM or ADPCM.
• Footer: The footer contains a checksum to verify the integrity of the file.

HMI Audio File Format

HMI Audio File (.HMI) is an audio file format developed by Human Machine Interfaces (HMI). It is a proprietary format used primarily for storing audio data in HMI systems, which are interfaces used in industrial automation and control applications. HMI files typically contain recorded audio messages or instructions that are played back to users through HMI devices, such as touchscreen panels or keypads.

Opening HMI Files

Opening HMI files requires specialized software that supports the HMI Audio File format. While there are no widely available consumer-grade applications that can handle HMI files, several HMI development suites and industrial automation software packages include utilities that can open and manipulate them. These software suites typically provide features for editing, converting, and playing back HMI audio files, making them essential tools for engineers and technicians working with HMI systems.

In some cases, HMI files can be converted to more common audio formats, such as WAV or MP3, using dedicated conversion utilities or certain HMI development software. However, conversion may not always be possible or may result in loss of data or fidelity. Therefore, it is generally recommended to use HMI-compatible software to work with HMI audio files whenever possible.

Human Machine Interfaces (HMI) and HMI Audio Files

Human Machine Interfaces (HMI) are devices that provide a graphical user interface for controlling machinery or equipment. They allow users to interact with machines using touchscreens, buttons, and other input methods. HMI audio files play a vital role in these interfaces, providing sound effects, alerts, and other auditory feedback to enhance the user experience.

HMI audio files are typically stored in the .HMI format, which is a proprietary format developed by HMI manufacturers. These files contain audio data in a compressed format, optimized for playback on HMI devices. HMI audio files can be created using various software tools, including HMI development environments and third-party audio editing programs. They can be customized to meet the specific requirements of the HMI application, including volume, sample rate, and audio codecs used.
