SCHNEIDER HARMONY GTU HMI

Schneider Harmony GTU HMI

Schneider Harmony GTU HMI for Advanced Machine Visualization & Industrial Control

Modern machines need more than a basic operator screen. Operators need clear process information, responsive controls, alarm visibility and reliable communication with PLCs, drives and other automation devices.

The Schneider Harmony GTU HMI is a high-performance modular touchscreen HMI designed for industrial machine and system automation. Formerly known as Magelis GTU, the Harmony GTU range combines different display modules with processing/box modules, allowing the HMI configuration to be selected according to the application's performance and communication requirements.

We Tech Power Solutions Ltd supplies Schneider Electric Harmony HMI solutions for machine builders, OEMs, panel builders and industrial users across Ahmedabad, Gujarat, India and selected Gulf markets.

What Makes Harmony GTU Different?

The main advantage of Harmony GTU is its modular architecture.

Instead of being limited to one fixed HMI configuration, users can select a compatible display and box module according to the required application. Schneider describes the range as offering flexibility in combining CPU/box modules with different display options.

This approach can be useful when:

• A machine requires a larger display

• Processing requirements differ between applications

• Communication interfaces need to be expanded

• An existing HMI configuration needs upgrading

• Different machines require different screen sizes

• Future maintenance and replacement flexibility are important

A Modular HMI Built Around the Application

Harmony GTU separates the display function from the processing/box function.

Display Module

The display provides the operator interface and is available in different sizes and resolutions depending on the selected model.

Schneider's current range covers display options from approximately 7 inches to 19 inches wide.

Examples include:

• 7-inch wide display

• 10.4-inch display

• 12.1-inch display

• Larger wide-screen configurations

• Model-specific display and touch technologies

Box Module

The box module provides the processing and communication capabilities required by the HMI.

Depending on the selected configuration, features can include:

• Ethernet communication

• Serial communication

• USB interfaces

• SD card storage

• Processing resources

• Remote-access functions

• Industrial communication capabilities

For example, Schneider's Premium Box configuration includes Ethernet, serial and USB interfaces, SD-card storage and an ARM Cortex-A9 processor.

Clear Visualization with Multi-Touch Operation

Harmony GTU is designed around a modern operator experience, with touchscreen interaction and multi-touch capability on applicable display modules.

A 10.4-inch GTU display such as the HMIDT542 provides:

• 10.4-inch colour TFT LCD

• 800 × 600 SVGA resolution

• 16 million colours

• Multi-touch analogue resistive touchscreen

• 12–24 V DC supply

• Natural-convection cooling

The 12.1-inch HMIDT642 provides a 1024 × 768 XGA display and multi-touch interface.

This makes the platform suitable for dashboards containing:

• Machine status

• Production values

• Alarm messages

• Trend information

• Process graphics

• Parameter settings

• Diagnostic screens

• Operator controls

Communication for Connected Automation Systems

A modern HMI often acts as the operator's window into the complete automation system.

Harmony GTU supports communication architectures designed to connect the HMI with controllers and industrial equipment. Schneider highlights combinations including dual Ethernet, dual serial communication and wireless Ethernet on applicable configurations.

Depending on the selected model, application architecture can include communication with:

• Schneider Modicon PLCs

• Industrial drives

• Remote I/O

• Automation equipment

• Industrial networks

• Other compatible third-party devices

This allows the GTU to be used as a central operator interface for machine control and monitoring.

IIoT-Ready HMI for Connected Machines

Harmony GTU is positioned by Schneider as a high-performance, IoT-ready HMI platform.

For connected industrial applications, selected GTU configurations support features such as:

• Remote machine access

• Web-based visualization functions

• Data transfer

• Ethernet connectivity

• Wireless connectivity on applicable models

• Data storage

• Communication with connected automation devices

Schneider also describes remote-access and Web Viewer/Web Gate capabilities across applicable GTU configurations and software environments.

HMI Software & Configuration

The software environment depends on the specific Harmony GTU display/box combination and product generation.

Schneider documentation associates GTU configurations with Vijeo Designer, while newer GTU configurations are also positioned with EcoStruxure Operator Terminal Expert. Schneider specifically identifies the GTU range as being powered by EcoStruxure Operator Terminal Expert, while certain wireless GTU configurations use Vijeo Designer.

Therefore, for a replacement or new project, the exact GTU model number and software compatibility should be confirmed before selecting the configuration.

Where Is Schneider Harmony GTU HMI Used?

Harmony GTU can be integrated into applications where operators need detailed visualization, machine controls and communication with industrial automation equipment.

Common Applications

• Machine control panels

• Production-line monitoring

• Packaging machines

• Process monitoring

• Manufacturing equipment

• Material handling systems

• Food and beverage machinery

• Water and utility systems

How to Select the Right Harmony GTU

Selecting a GTU should be based on the complete automation requirement rather than only the screen size.

1. Determine the Display Size

Choose the screen according to viewing distance, dashboard complexity and available panel space.

2. Check the Processing Requirement

Select the appropriate box module according to application complexity and required performance.

3. Verify Communication

Confirm Ethernet, serial, wireless or other communication requirements before ordering.

4. Check Software Compatibility

Verify whether the selected hardware uses Vijeo Designer or EcoStruxure Operator Terminal Expert.

5. Consider Environmental Conditions

Review temperature, humidity, dust, vibration and required certifications for the installation environment.

6. Confirm Panel Dimensions

For replacement projects, compare the existing panel cut-out and mounting arrangement with the new GTU display.

7. Confirm the Complete Order Number

Harmony GTU is a modular family, so the exact display and box references are essential for correct selection.

Harmony GTU for HMI Replacement & Retrofit

For industrial retrofit projects, replacing an older Magelis HMI is not simply a matter of selecting the same screen size.

The existing system should be checked for:

• Original HMI model

• PLC model

• Communication protocol

• Existing HMI project

• Software version

• Panel cut-out

• Display dimensions

• Power supply

• Required accessories

• Environmental conditions
