Pro-face GP4105G1D

The Pro-face GP4105G1D is a compact, high-quality monochrome Human Machine Interface (HMI) belonging to the GP4100 Series.¹ Manufactured by Pro-face (by Schneider Electric), this 3.4-inch unit is designed to provide a graphical interface for small machines, replacing traditional push-buttons and text displays.

The “G1D” in the model name specifically refers to its Green/Orange/Red tri-color LED backlight.²

1. Display and Visuals

• Screen Size: 3.4-inch.³

   

• Display Type: Monochrome LCD (Black/White).

• Resolution: ⁴$200 \times 80$ pixels.⁵

   

• Backlight: 3-Color LED (Green, Orange, Red). * This is a key feature: you can program the screen to turn Red during an alarm, Orange for a warning, and Green for normal operation, allowing operators to see the machine status from a distance.⁶

   

• Touch Panel: Analog resistive touch screen (allows for custom button placement).⁷

   

2. Connectivity and Ports

The GP4105 variant is specifically designed for Serial RS-232C communication.

• Serial (COM 1): RS-232C via a 9-pin D-Sub connector. Used to communicate with PLCs, temperature controllers, or inverters.⁸

   

• USB (Mini-B): Located on the back for high-speed screen transfers and programming via a PC.

• USB (Type A): One port for connecting peripheral devices like a barcode reader or for transferring data via a USB stick.⁹

   

3. Hardware and Performance

• Memory: 2.2 MB internal Flash memory for storing project screens and images.

• Data Retention: It features a built-in battery-less memory (NVRAM) to keep data safe even without power.

• Clock: Built-in Real-Time Clock (RTC) for time-stamping alarms and events.

5. Key Advantages

• Compact Size: Ideal for mounting in tight spaces or on small control boxes.

• High Resolution: For its size, the $200 \times 80$ resolution provides very sharp text and clear icons.

• Universal Connectivity: Pro-face is famous for its “Best-in-Class” drivers, allowing this HMI to talk to almost any PLC brand (Siemens, Mitsubishi, Omron, ABB, etc.).

Comparison Note:

• GP4105: Uses RS-232C communication.¹⁰

   

• GP4106: Uses RS-422/485 communication.

• GP4107: Is the Ethernet version.
