The Pro-face 3.8-inch touchscreen model AGP3301H-T1-D24-RED is a compact and reliable human-machine interface (HMI) designed for industrial automation environments. Operating on a DC24 power supply, this standard-grade (S-class) unit is engineered for durability and ease of use in demanding production settings.

Featuring a 3.8-inch TFT true-color LCD display with a resolution of 320×240 pixels (QVGA), the screen delivers clear and vibrant visuals. It supports 256 colors in non-flicker mode and 64 colors with 3-speed flicker options, allowing for flexible visual feedback. The backlight uses a white LED, which can only be replaced through factory repair service. Brightness is adjustable in 16 levels directly via the touch panel, ensuring optimal visibility under various lighting conditions.

The touch panel is a resistive analog type, offering reliable and precise touch input even when used with gloves or in harsh conditions. To accelerate programming, Pro-face provides a rich library of pre-designed sample screens and 3D components, enabling users to create intuitive and visually appealing interfaces with minimal effort.

Data transfer is simplified through USB memory support, allowing operators to quickly update screen data in response to production line changes without complex cabling or software reconfiguration. The unit is supported by the powerful GP-Pro EX software, which features a user-friendly drag-and-drop interface. Even beginners can quickly learn to create screens using advanced tools such as 3D parts, image fonts, and built-in functions.

Maintenance is made more efficient with video-based operation and maintenance instructions, which can be accessed directly on the unit. This reduces training time and helps ensure consistent operational procedures. For development and testing, the PC simulation function allows users to verify all GP functions — including screen transitions, D scripts, and logic scripts — without needing to transfer data to the actual hardware.

Remote operation and monitoring are also supported, enabling users to view and interact with GP screens from an office or other remote location. This capability facilitates real-time management and more efficient remote maintenance control without requiring additional programming or screen editing.

Error visualization is enhanced by directly connecting controllers to the GP. Using pre-built sample components, critical error information from the controller can be displayed clearly, helping operators quickly identify and address issues.

Security is managed through a password-based system that restricts access to screens based on operator or administrator roles. Each user must enter an ID and password to operate the device, ensuring that only authorized personnel can make changes. This supports safety and control in production environments.

The GP also features a data pass-through function, allowing users to debug PLC programs and adjust production line parameters directly through the HMI without needing to open the control cabinet. For data logging, USB memory or CF card support enables efficient daily and monthly report backups. CSV data conversion functionality allows PLC settings to be modified directly from the GP.

Backward compatibility is a key advantage: the GP/ST series supports screen data from all previous GP models, including the first-generation GP10 series. Additionally, the product family maintains panel cut-out compatibility, ensuring easy replacement and upgrade paths without major modifications to existing installations.

In summary, the AGP3301H-T1-D24-RED is a feature-rich, compact HMI that combines ease of use, robust performance, and advanced functionality to meet the needs of modern industrial automation and production line management.
