Product Introduction
The Allen-Bradley 2711-K3A17L1 is a PanelView 300 standard operator terminal with a 3-inch monochrome LCD and keypad. It provides RS-232 (DF1) communication for integration with SLC 500, MicroLogix, and early CompactLogix systems in legacy installations.
This HMI is chosen for simple machine interfaces where a compact, low-cost display with keypad input is sufficient. In field deployments, it’s commonly used on small machines, conveyors, and skids where only basic start/stop, setpoint, and alarm display are needed.

Troubleshooting Quick Reference
| Symptom | Possible Cause | Relevance to this Part | Quick Check Method | Recommendation |
|---|---|---|---|---|
| No display, no backlight | 24 V DC supply missing or wiring fault | ✅ High | Measure 18–32 V DC at input terminals; check polarity and fuse | Fix 24 V DC supply and wiring before swapping HMI |
| Backlight on but screen blank | Application not loaded or corrupted | ✅ Medium | Check for “No Application” or similar message; try PanelBuilder 32 download | Reload application; verify RS-232 node and baud settings |
| Keys unresponsive or intermittent | Membrane damage or contamination | ✅ Medium | Inspect keypad overlay; run key test in terminal setup | Replace keypad/membrane if keys are stuck or unresponsive |
| RS-232 communications failing | Node address/baud mismatch or cable fault | ✅ High | Verify DF1 node, baud rate, and cable continuity; monitor with RSLinx | Correct DF1 config; replace RS-232 cable if open/short |
| Display dim or faint | Backlight aging or driver issue | ✅ Medium | Measure backlight brightness; check for dimness in bright ambient light | Replace backlight assembly (2711-NL3) if dim/faint |
| Application data lost after power-off | Non-volatile memory fault or corruption | ✅ Low | Check if application reverts to default after power cycle | Reload application; replace terminal if corruption persists |
If you’re stuck, send photos of the terminal (including rating label), a screenshot of the blank screen or fault, and your RS-232/DF1 settings. We’ll review it before you swap the unit.
Frequently Asked Questions (FAQ)
Q: Is the 2711-K3A17L1 hot-swappable?
A: No. The 2711-K3A17L1 must be installed and removed with 24 V DC power OFF. Hot-swapping can damage the power supply and communication ports.
Q: What’s the difference between 2711-K3A17L1 and 2711-K3A1L1?
A: Both are PanelView 300 monochrome terminals. K3A17L1 uses RS-232 (DF1) and RS-232 printer. K3A1L1 uses RS-485 (DH-485) and RS-232 printer. Choose based on your network (DF1 vs DH-485).
Q: Can I use the 2711- with ControlLogix over EtherNet/IP?
A: No. The 2711- has RS-232 (DF1) and serial printer ports only. For EtherNet/IP, you need a PanelView Plus or newer HMI with an Ethernet port.
Q: What software do I need to program the 2711-?
A: PanelBuilder 32 is used to create and download applications to the 2711-. It runs on Windows and communicates via RS-232 (DF1).
Q: What condition are these units in, and why is pricing lower than factory?
A: We sell New Original (New Surplus) and Refurbished (tested) units. Pricing is lower because these are surplus or professionally refurbished, and the PanelView 300 line is discontinued. Each refurbished unit goes through power, display, and communication tests and comes with a 1-year warranty.
Q: Can I keep my existing application when swapping a failed 2711-?
A: Yes, if the replacement is the same catalog number and you have a PanelBuilder 32 backup. Download the existing .MER runtime file to the new terminal and verify DF1 node and baud settings.
Q: What is the recommended replacement for the 2711-?
A: Rockwell’s migration path is PanelView Plus 6 / 7 (e.g., 2711P-… series) with FactoryTalk View ME. Migration requires application conversion and new communication wiring (Ethernet or serial, depending on model).
