Schneider HMIST6500 Magelis STO HMI Touch Screen

The Schneider HMIST6500 is a 5.7 inch monochrome touch screen HMI from the Magelis STO series. Designed for simple machine control and operator interface applications, this unit provides a clear, backlit LCD display with resistive touch technology. It operates on 24V DC power, making it suitable for industrial environments where reliability and cost-effectiveness are priorities.

Display Specifications

The screen is a 5.7 inch STN monochrome LCD with 320 x 240 pixel resolution (QVGA). It features a white LED backlight with a typical lifetime of 50,000 hours. The display is readable in ambient light without external illumination. The resistive touch panel is activated by finger or stylus, with a response time of less than 10 ms. The viewing angle is 70° in all directions.

Memory and Processing

The HMIST6500 includes 8 MB of flash memory for application storage and 2 MB of RAM for runtime execution. It can handle up to 200 data points and 50 alarm messages. The real-time clock is battery-backed, providing timestamping for events. The processor is a 32-bit RISC CPU running at 120 MHz.

Communication Ports

The unit provides one serial port (RS-232C/422/485) supporting Modbus RTU, Uni-TE, and Schneider’s proprietary protocols. An optional Ethernet module can be added via the expansion slot. There is also a USB 1.1 host port for data transfer to a USB drive or connection to a mouse. The HMI can communicate with Schneider PLCs such as M340, M221, and Modicon Quantum.

Software and Configuration

Programming is done using Schneider’s Vijeo Designer software, which offers a library of preconfigured objects, alarms, trends, and recipes. The software supports multi-language projects (up to 10 languages). Application download is via USB or serial cable. The HMIST6500 also supports remote monitoring via web server when the Ethernet option is installed.

Environmental and Power

Power supply: 24V DC (±10%), consumption 8W typical. The front panel is rated IP65 for dust and water resistance. Operating temperature: 0°C to 55°C; storage: -20°C to 60°C. Humidity: 10% to 90% non-condensing. Dimensions: 166 x 128 x 71 mm (W x H x D). Panel cutout: 154 x 117 mm. Weight 0.65 kg.

Diagnostic Features

The HMI has a built-in diagnostic screen accessible via a startup key combination, showing firmware version, memory usage, and communication status. Redundant LEDs indicate power and CPU activity. The unit performs a self-test at boot, checking the screen and touch controller.

Applications

Ideal for small packaging machines, conveyor control panels, pump stations, and HVAC terminals. The monochrome display is well-suited for text-based menus and simple graphics in cost-sensitive applications.

Conclusion

The Schneider HMIST6500 Magelis STO touch screen HMI offers a compact, durable 5.7 inch interface with serial communication and optional Ethernet. Its low power consumption and IP65 rating make it a reliable choice for basic machine operator panels.
