Pro face GP577R-TC11 HMI: 10.4 Inch Color TFT Touch Screen Operator Interface

The Pro face GP577R-TC11 is a color touch screen HMI from the GP5000 series, offering a 10.4-inch TFT LCD display with 256 colors (8-bit) and a resolution of 640 x 480 pixels (VGA). It is designed for demanding industrial applications requiring clear visualization of process data, trends, and alarms. The GP577R-TC11 supports multiple communication protocols and features a rugged construction rated IP65 for the front panel. It is an ideal choice for machine control panels, process monitoring, and data entry.

Display Specifications

The TFT active matrix display provides a wide viewing angle (left/right ±55°, up/down ±40°) and a brightness of 350 cd/m². Contrast ratio is 300:1. Backlight is a CCFL tube with a typical life of 50,000 hours (replaceable). The display supports 256 colors (8-bit) from a palette of 4096 colors. The resistive analog touch panel has a resolution of 1024 x 1024, requiring 0.5 to 1.0 N activation force. The touch panel is durable for over 1 million operations per point.

Memory and Processing

The GP577R-TC11 includes 4 MB of flash memory for screen storage and 256 KB of battery-backed SRAM for recipes and logs. The CPU is a 32-bit RISC processor (80 MHz). It supports up to 500 screens, 128 alarms, and 32 data logs. The real-time clock is battery-backed (lithium, 5-year life). Data transfer between screens is typically under 0.1 seconds. The HMI also supports macro execution for arithmetic and conditional operations.

Communication Ports and PLC Connectivity

The unit features two serial ports: COM1 (RS-232C) and COM2 (RS-422/485). It supports direct connection to a wide range of PLCs including OMRON (Host Link, NT Link), Mitsubishi (FX, Q series), Siemens (PPI, MPI), Allen Bradley (DF1), and many others (over 100 drivers). An optional Ethernet module (GP577-ETH) can be installed for network connectivity. The HMI also has a printer port (Centronics) for hardcopy output.

Programming and Software

Pro-face GP-Pro EX software (version 2.0 or later) is used to create projects. The software provides object-oriented design, a library of symbols, and simulation capabilities. It supports multi-language text (up to 16 languages, switchable online). The HMI is also compatible with GP-PRO/PBIII for Windows (for legacy projects). Programming is transferred via RS-232C or Ethernet. The software includes security features such as password-protected screens and operator authentication.

Environmental and Mechanical Data

Front panel protection: IP65 (when properly installed). Rear: IP20. Operating temperature: 0°C to 50°C, storage -20°C to 60°C. Humidity: 10% to 90% non-condensing. Vibration resistance: 10-57 Hz, 0.075 mm amplitude. Dimensions: 305mm (W) x 235mm (H) x 55mm (D). Panel cutout: 290mm x 222mm. Weight: 2.5 kg. Power supply: 24 VDC (20.4 to 27.6 V), consumption 28 W typical. The HMI meets CE, UL, and RoHS standards.

Typical Applications

The GP577R-TC11 is used in CNC machine controls, packaging machinery, plastic injection molding, and printing presses. The color display allows intuitive presentation of process status, alarm locations, and trend charts. It can replace multiple analog gauges and indicator lights. Its communication versatility makes it suitable for retrofitting existing PLC-based systems without changing the control architecture.

Accessories and Ordering

Order number: GP577R-TC11. The unit is supplied with mounting brackets and a power connector. Optional items: protective overlay (GP577-AT01), backlight replacement kit (GP577-BL00), Ethernet module (GP577-ETH), and replacement mounting clips (GP577-CLIP). Pro-face provides a 3-year warranty. The GP577R-TC11 has been succeeded by the GP4000 series, but this model remains available for replacement purposes. For new installations, consider the GP-4500 series for enhanced performance.
