Product Overview
The Schneider HMIG3U is a Harmony GTU base unit for modular HMI installations. It forms the base section of the GTU architecture and is used together with a compatible display module to create a complete operator interface.
The modular arrangement separates the HMI base unit from the display, allowing the operator interface to be assembled according to the requirements of the machine or control cabinet. The HMIG3U can serve as the HMI platform for applications where operators need to monitor equipment, manage parameters, respond to alarms, and interact with machine functions.
In a typical automation architecture, the base unit works with the selected GTU display and communicates with PLCs and other control equipment as part of the operator interface system.

Working Principle
The HMIG3U functions as the base section of a modular Harmony GTU HMI. The base unit handles the underlying HMI system functions, while the compatible display module provides the operator-facing visual interface.
The HMI communicates with the connected automation system and exchanges application data with the controller. Information such as machine status, process values, alarms, and configured parameters can then be presented through the attached display.
Operator interactions are handled through the complete HMI assembly. Commands, parameter changes, alarm acknowledgements, and screen navigation are processed by the HMI and exchanged with the control system as required by the application.
