Product Overview
The Allen-Bradley 2711P-T6M3D is a PanelView Plus 600 operator terminal designed for reliable machine-level visualization and control in industrial environments. As part of the PanelView Plus Graphic Terminals family, this unit combines a 5.5-inch grayscale display with an analog resistive touchscreen, making it a practical choice for small-scale applications that require straightforward operator interaction.
With multiple communication ports—RS-232, Ethernet, and DH485—the 2711P-T6M3D integrates easily into existing Rockwell Automation architectures. Its 18–32 VDC input voltage range and nominal 24 VDC operation provide flexibility for various control panels. Although this product is now classified as obsolete/discontinued by the manufacturer, it remains a viable spare part for legacy systems that are still in service.

Key Features & Benefits
-
Versatile Connectivity: Built-in RS-232, Ethernet, and DH485 ports support peer-to-peer and multi-node communication, enabling integration with PLCs, drives, and other control devices.
-
Intuitive Touch Interface: The analog resistive touchscreen allows operators to navigate screens and enter data directly, reducing training time.
-
Compact Form Factor: The 5.5-inch display and lightweight 930 g design make it easy to mount in control panels where space is limited.
-
Durable Backlight: The CCFL backlight is rated for 50,000 hours minimum, minimizing maintenance frequency.
-
Flexible Power Input: Accepts 18–32 VDC, accommodating variations in plant power supplies.
Applications
The 2711P-T6M3D is well-suited for small-scale industrial automation tasks such as:
- Monitoring and controlling packaging machinery, where the monochrome display provides clear status indication without the need for color graphics.
- Operating conveyor systems that require simple operator inputs like start, stop, and alarm acknowledgment.
- Retrofitting legacy control panels that need a reliable HMI replacement while maintaining existing communication protocols.
Because of its RS-232 and DH485 support, this terminal works effectively with older Allen-Bradley PLCs (e.g., SLC 500, MicroLogix) as well as newer Ethernet-enabled controllers, making it a flexible upgrade path.
Installation & Setup Guidance
Mount the 2711P-T6M3D into a panel cutout using the provided mounting clips. Ensure adequate clearance behind the unit for wiring and ventilation. Connect the DC power supply to the terminal's power input terminals, observing correct polarity. For communication, use standard Ethernet cables for the Ethernet port, and RS-232/DH485 cables with appropriate connectors for serial devices. After power-up, configure the communication settings (baud rate, node address, etc.) via the configuration menu. The unit supports the addition of communication modules (e.g., ControlNet, DeviceNet, DH+/DH-485/Remote I/O) if needed, allowing flexibility for changing network requirements.
Maintenance & Reliability
To ensure long-term reliability, periodically inspect the backlight for dimming—the CCFL is rated for 50,000 hours, but actual life may vary with operating temperature. Clean the touchscreen with a soft, dry cloth; avoid abrasive cleaners. Check that all connectors remain tight, especially in vibration-prone environments. Because this unit is obsolete, it is advisable to keep a spare on hand to minimize downtime.
Selection Guide & Purchasing Advice
Before purchasing, verify that the 2711P-T6M3D meets your application requirements. Confirm the power supply voltage (18–32 VDC) and available communication ports. If you need to interface with a specific PLC, ensure the protocol is supported (RS-232, Ethernet, DH485). Since this product is discontinued, availability may be limited; it is prudent to source from a reputable supplier that tests and guarantees functionality. PLC Source PRO offers quality-checked surplus and obsolete automation parts, providing a reliable option for maintaining legacy systems.
