Product Overview
The Schneider Electric HMIGXU3500 is a 7-inch basic touchscreen panel from the Harmony Easy GXU series. It is intended for straightforward machine-level visualization, where operators need to view equipment status, enter operating values, and interact with a PLC without the additional communication functions found in more advanced HMI models.
Unlike the universal HMIGXU3512, the HMIGXU3500 uses a basic communication configuration with one RS-422/RS-485 serial port and one USB Mini-B connection. It does not include an integrated Ethernet port or USB Type-A host interface. This distinction is important when selecting a replacement terminal or planning the communication arrangement of a machine.
The display uses an 800 × 480 WVGA color TFT touchscreen with 65,536 colors. Its 7-inch screen is suitable for presenting machine operating parameters, numerical indicators, status messages, and basic graphical controls. The application is developed using Vijeo Designer Basic, which provides the tools required to configure screens and establish communication with compatible controllers.
The HMIGXU3500 includes 32 MB of application memory, 128 MB of internal DDR memory, and 128 KB of backup memory. An integrated real-time clock maintains time-related information, while its replaceable RTC battery supports clock operation when the panel is not powered.
In a typical installation, the HMIGXU3500 is connected to a compatible PLC through its serial communication interface. The PLC handles machine logic and field signal processing, while the HMI displays operating information and accepts commands from production personnel. This arrangement is suitable for compact packaging equipment, pumps, machine tools, and other applications with relatively simple operator-interface requirements.

Product Features
- 7-Inch WVGA Color Touchscreen
The HMIGXU3500 features a 7-inch TFT color display with an 800 × 480-pixel resolution. It supports machine operating screens, numerical displays, status indicators, and basic graphical interfaces used in everyday production operations.
- Basic Serial Communication
The terminal provides one COM1 serial interface supporting RS-422 and RS-485 communication. This configuration is suitable for PLC connections and other compatible serial automation devices.
- 32 MB Application Memory
The internal 32 MB Flash memory stores the configured HMI application. Engineers can develop operator screens, numerical displays, and machine-control interfaces using Vijeo Designer Basic.
- 128 MB Internal DDR Memory
The integrated DDR memory supports application execution and screen operation during normal use.
- Integrated Real-Time Clock
The built-in RTC maintains time-related information for applications that use timestamps, operating records, or clock-based functions. Its replaceable battery supports clock retention when external power is removed.
- USB Mini-B Connection
The USB Mini-B interface provides a connection for supported application transfer and engineering operations. Unlike the universal GXU models, the HMIGXU3500 does not include a USB Type-A host port.
- IP65 Front Protection
The front panel has an IP65 protection rating when installed correctly in a suitable enclosure. This helps protect the operator interface against dust and water jets.
- Compact Basic Configuration
The HMIGXU3500 focuses on essential visualization and serial communication functions. Its simplified interface configuration makes it appropriate for machines that do not require an integrated Ethernet connection.
- Vijeo Designer Basic Support
The terminal is configured through Vijeo Designer Basic. Engineers can create screen layouts, configure serial communication, define operating parameters, and organize machine information within the HMI application.
Working Principle
The HMIGXU3500 operates as the local visualization and operator-input device in a serial PLC control system. It exchanges data with the connected controller through its COM1 RS-422/RS-485 interface.
During normal machine operation, the PLC processes signals from sensors, switches, motors, and other field devices. Selected operating variables are made available to the HMI through the configured communication protocol.
The HMIGXU3500 reads these variables and updates the corresponding screen objects. Operators can view equipment conditions, check numerical values, review machine messages, and enter authorized parameters through the touchscreen.
When an operator selects a configured control or changes a setpoint, the HMI sends the corresponding data through the serial connection. The PLC receives the input and evaluates it according to its control program before executing the requested machine operation.
The basic model is particularly relevant where Ethernet communication is unnecessary. For example, a compact pumping machine may use an RS-485 connection between the HMI and PLC. The panel displays pump status, operating pressure, accumulated running time, and alarm information, while the controller manages the actual pump sequence.
Application development and transfer are handled through Vijeo Designer Basic and the supported USB Mini-B connection. The integrated RTC also allows applications to use clock-related information where required.
Typical Communication Path:
PLC / Controller → RS-422 or RS-485 → HMIGXU3500 → Touchscreen Display → Operator Input → PLC
Application Development Path:
Engineering Computer → Vijeo Designer Basic → USB Mini-B Connection → HMIGXU3500
Role in Harmony Easy GXU Control Architecture
Within the Harmony Easy GXU range, the HMIGXU3500 serves as a basic operator interface for machines that require local visualization and serial communication rather than a more extensive network configuration.
Its single serial interface connects the terminal to a compatible PLC. The controller continues to handle field I/O processing, machine sequences, and equipment control, while the HMI provides the operator with access to configured information and commands.
The distinction between the basic and universal GXU configurations is important when planning system integration. The HMIGXU3500 does not have the Ethernet and USB Type-A interfaces available on models such as the HMIGXU3512. A replacement or system upgrade must therefore account for the original communication method and required application functions.

Technical FAQs
What is the difference between HMIGXU3500 and HMIGXU3512?
Both models belong to the 7-inch Harmony Easy GXU range and use an 800 × 480-pixel WVGA display. The HMIGXU3500 is the basic version with one RS-422/RS-485 serial port and one USB Mini-B connection. The HMIGXU3512 is the universal version, adding Ethernet, USB Type-A, and a second serial communication interface. Their communication capabilities should be considered when selecting a replacement.
Does the HMIGXU3500 support Ethernet communication?
No. The HMIGXU3500 does not have an integrated Ethernet port. Its controller communication is handled through the COM1 RS-422/RS-485 serial interface. Applications requiring an Ethernet connection should use a suitable alternative HMI configuration.
Which software is required to program the HMIGXU3500?
The terminal uses Vijeo Designer Basic configuration software. The engineering project can be developed on a compatible computer and transferred to the HMI through its USB Mini-B connection using the supported programming cable.
What happens if the HMIGXU3500 RTC battery needs replacement?
The integrated real-time clock uses a replaceable battery to maintain clock information when the panel is disconnected from its external power supply. If the clock repeatedly loses its settings after power interruptions, the battery should be inspected and replaced according to the maintenance procedure.
