TouchWin TG765-MT

The TouchWin TG765-MT is a highly popular 7-inch color touch screen HMI manufactured by Xinje (Thingaive). It is widely used in compact machinery because of its high-speed performance, sharp display, and excellent compatibility with various PLC brands.

The “MT” in the model name indicates that it is a standard model featuring high-speed communication ports and a high-resolution screen.

1. Display and Visuals

• Screen Size: 7-inch Widescreen (16:9).

• Display Type: 16.77 million color TFT LCD.

• Resolution: $800\times 480$ pixels (WVGA).

• Backlight: LED backlight with a lifespan of 50,000 hours.

• Contrast: High contrast ratio, making text and small icons very easy to read even in bright industrial environments.

2. Connectivity and Ports

The TG765-MT is designed to be the communication hub of a machine:

• COM 1: RS-232 / RS-485 (used for the primary PLC connection).

• COM 2: RS-232 / RS-485 / RS-422 (flexible port for secondary devices like inverters or temperature controllers).

• USB-B Port: Located on the rear for high-speed program download/upload from a PC.

• USB-A Port: Allows for connecting a USB flash drive for data logging, firmware updates, and recipe storage.

3. Hardware Performance

• Processor: 32-bit RISC CPU (running at 400MHz or higher depending on the hardware version).

• Memory: 128 MB Flash for project storage and 128 MB RAM for fast operating speeds.

• Data Storage: Built-in RTC (Real-Time Clock) and persistent memory for alarm and event logging.

4. Technical Specifications

5. Key Features

• Multi-PLC Support: It supports a vast range of communication protocols including Modbus RTU/ASCII, and drivers for Siemens, Mitsubishi, Omron, Delta, and Schneider.

• C-Language Macros: Users can write “C” scripts within the HMI to handle complex math, data manipulation, or protocol conversions that the PLC cannot handle easily.

• Fast Response: The touch response and screen switching are very smooth compared to older monochrome or text-based panels.

• Animation Support: It can handle simple GIF-like animations to show moving parts of a machine (e.g., rotating fans or moving conveyors).

Maintenance Tip: If the HMI screen stays stuck on the “System Loading” screen, it often indicates a corrupted project file or a firmware issue. You can try to “Force Download” the project from the TouchWin software using the USB-B cable.

Would you like me to find the “Communication Pinout” for a specific PLC (like the Xinje XC series or Mitsubishi FX), or do you need the “Installation Manual” for the software?
