The Pro-face AGP3550-T1-AF is a rugged handheld touchscreen HMI designed for demanding industrial environments. Operating on a DC24 power supply, it is part of the handheld-grade series, offering portability and ease of use for on-the-go operations. Its 5.7-inch monochrome LCD display delivers clear visuals with a resolution of 320x240 pixels (QVGA) and supports 16-level grayscale for detailed graphical representation. The white LED backlight ensures consistent visibility, though replacement requires factory service. Brightness can be adjusted in 16 steps directly via the touch panel, which employs analog resistive technology for precise input.

This model excels in error visualization by directly connecting to controllers. Using pre-built sample parts, critical error information from the controller can be displayed on the GP screen, allowing operators to quickly identify and troubleshoot issues without accessing the control cabinet. Additionally, the GP supports PLC program monitoring and editing, enabling technicians to debug ladder logic and adjust production line parameters remotely through the HMI.

The data pass-through function further streamlines maintenance by allowing seamless communication between a PC and PLC via the GP. This facilitates efficient debugging and data adjustment without physical connection to the controller. For data management, the AGP3550-T1-AF supports USB memory and CF cards, enabling fast backup of daily and monthly reports. The CSV data conversion feature allows direct modification of PLC settings from the GP, enhancing workflow efficiency.

Simulation capabilities are robust, with PC-based runtime testing that emulates all GP functions—including screen transitions, D scripts, and logic scripts—without requiring data transfer to the actual device. Remote operation and monitoring are also supported, allowing users to access and control GP screens from an office or remote location. This real-time management capability eliminates the need for additional programming or screen editing, improving remote maintenance and control.

The device integrates five key efficiency-enhancing features. Using the GP-Pro EX software, users can create intuitive, high-quality screens with drag-and-drop simplicity, 3D components, image fonts, and other advanced tools. Even beginners can quickly develop professional interfaces. Video-based operation and maintenance instructions reduce training costs, as any operator can follow visual guides for tasks. For system upgrades, the AGP3550-T1-AF ensures backward compatibility with all GP series screen data, including the original GP10 series, while maintaining panel cutout compatibility for easy replacement.

Pre-built sample screens and 3D parts significantly reduce programming time. Data transfer via USB memory simplifies updating screen data for production changes. Security is addressed through password management, allowing customizable access levels based on operator or supervisor roles. Each user must enter an ID and password to operate equipment, ensuring that only authorized personnel can access specific functions, thus minimizing workplace issues and enhancing overall operational safety.
