Product Overview
The Schneider Electric HMIST6400 is a 7-inch wide-format touch panel screen in the Harmony ST6 series. It provides a local operator interface for industrial machines, allowing operators to monitor operating conditions, view alarms and interact with configured HMI screens without requiring a computer at the machine.
The 800 × 480 pixel color display is suitable for equipment that needs more screen space than a compact 4.3-inch terminal can provide. Machine builders can organize operating values, status indicators, alarm lists and touch controls across a single interface, making it useful for packaging machinery, material-handling equipment and compact production systems.
The HMIST6400 operates from a 24 V DC supply and supports Ethernet, serial communication and USB connections. It uses a single-touch resistive panel and runs HMI applications developed with compatible EcoStruxure Operator Terminal Expert software. The panel handles visualization and operator input; machine sequencing and field I/O are managed by the connected controller.

Working Principle
The HMIST6400 runs the configured HMI application and exchanges data with a connected controller or other supported automation equipment. The application determines which values appear on the display, how screen navigation works and which operator actions are available.
For example, on a packaging machine, the screen may show production counts, operating mode, sensor status and active alarms. An operator can navigate to a setup screen or enter a permitted setpoint. The HMI sends the configured command or value through the selected communication interface, while the controller processes the command and manages the machine sequence.
The two Ethernet ports and serial interfaces provide communication options for compatible devices. The actual protocol, tag mapping and network arrangement depend on the connected equipment and application configuration. The HMIST6400 does not replace the PLC or machine controller responsible for control logic and field I/O.
Role in a Harmony ST6 HMI Architecture
The HMIST6400 acts as the visualization and operator-input layer of a machine automation system. It presents data received from the controller and sends configured operator commands through supported communication connections.

Installation and Maintenance
- Verify the model reference: Confirm HMIST6400 and the required communication interfaces before installation.
- Check the panel cutout: Prepare the specified 190 × 135 mm opening and confirm that the mounting arrangement matches the installation requirements.
- Inspect the mounting location: Ensure the screen is accessible to operators and that the installation allows sufficient ventilation.
- Confirm the power supply: Provide a suitable 24 V DC supply and verify polarity and circuit protection before connecting the panel.
- Isolate power before wiring: Disconnect the supply before installing or removing power and communication cables.
- Check Ethernet connections: Confirm the network cabling, connected devices and communication settings for the intended application.
- Verify serial wiring: Match the COM interface wiring and communication parameters to the connected equipment.
- Check USB compatibility: Connect only supported peripherals or engineering equipment to the appropriate USB port.

Technical FAQs
What is the difference between the HMIST6400 and HMIST6200 displays?
The HMIST6400 has a 7-inch wide display with 800 × 480 pixel resolution, while the HMIST6200 has a 4.3-inch wide display with 480 × 272 pixel resolution. The larger HMIST6400 offers more screen space for alarms, operating values and touch controls.
How many Ethernet and serial interfaces does the HMIST6400 provide?
The HMIST6400 provides two Ethernet ports and two COM serial interfaces, along with one USB host port and one USB device port. The usable connection and protocol depend on the connected equipment and application configuration.
Can the HMIST6400 directly control motors and field actuators?
The HMIST6400 is an HMI terminal, not a standalone field-I/O controller. It can display operating information and send configured commands to a compatible PLC or machine controller, which handles control logic and actuators.
What should be checked before replacing another HMI with the HMIST6400?
Check the panel cutout, 24 V DC supply, Ethernet or serial communication requirements, controller compatibility and HMI project configuration. The replacement project must be compatible with the HMIST6400 and correctly map the displayed values and operator commands to the connected system.
