2711P-T12C4D2 | Allen-Bradley PanelView Plus 1250 Color/Touch/Enet/RS232, DC Power

The 2711P-T12C4D2 is a Human-Machine Interface (HMI) terminal from the PanelView Plus 1250 series, designed to allow operators to visualize, monitor, and control industrial processes. It provides real-time graphical feedback and touchscreen-based control for machines and production lines. With its 12.1-inch color display and resistive touchscreen, users can interact with control systems using intuitive process graphics. The HMI supports data input, alarm monitoring, and navigation between screens. It connects to PLCs and other controllers, facilitating efficient operation and decision-making on the plant floor. This device is essential in automation environments where human supervision and control are required.

The 2711P-T12C4D2 features a 12.1-inch color TFT (Thin-Film Transistor) LCD with a resolution of 800 x 600 pixels. It includes a Cold Cathode Fluorescent Lamp (CCFL) backlight with a brightness of 300 Nits and a lifespan of 50,000 hours. This type of display ensures clear visualization in typical industrial lighting conditions. The high resolution supports complex graphic layouts and precise operator control. While CCFL backlights are less energy-efficient than LED, they were standard at the time of manufacture. Modern replacements typically use LED for longer life and lower power consumption.

The 2711P-T12C4D2 comes with 128 MB of RAM and 128 MB of non-volatile flash memory. The RAM supports runtime operation, including application loading and screen transitions. The flash memory is used for storing the application files, system firmware, and logs. This capacity supports moderately complex HMI applications with multiple screens, alarms, and data logging. Applications are typically developed and downloaded using FactoryTalk View ME software. If needed, application updates can be performed via USB or Ethernet.

Yes, the 2711P-T12C4D2 supports limited compatibility with third-party devices, particularly via Ethernet and serial (RS-232) connections. While it is optimized for use with Rockwell Automation’s products like CompactLogix, MicroLogix, and PLC-5, it can interface with other systems that support compatible communication protocols (e.g., Modbus through drivers). However, functionality may be reduced when operating outside of Allen-Bradley’s ecosystem. For critical or advanced features, using with Rockwell controllers ensures full compatibility.

No, the 2711P-T12C4D2 has been discontinued by Rockwell Automation. While the PanelView Plus 1250 series was widely used, it has been replaced by the PanelView Plus 7 Performance and PanelView 5000 families. Despite its discontinuation, many units remain in service, and spare parts, such as logic modules and screens, are still available from authorized vendors and aftermarket sources. Users are encouraged to consider migration strategies for long-term system support. Rockwell offers documentation and conversion tools to help update applications to newer HMI models.
