Machine Control HMI Solution – Allen-Bradley 2711C-K3M | PanelView C300 Series
Where This Product Is Used
The Allen-Bradley 2711C-K3M PanelView C300 Mono/Keypad is a compact human-machine interface (HMI) terminal engineered for demanding industrial environments. Engineers and system integrators deploy this unit across a wide range of applications:
- Conveyor & Material Handling Systems — operator control panels for start/stop, speed reference, and fault acknowledgment on belt and roller conveyors
- Packaging Machinery — line-speed control, batch counting, and recipe selection on form-fill-seal and cartoning equipment
- Pump & Compressor Stations — local operator interface for pressure setpoints, run/stop commands, and alarm display in water treatment and oil & gas facilities
- HVAC & Building Automation — zone control terminals integrated with MicroLogix or CompactLogix PLCs for temperature and airflow management
- Machine Tool & Assembly Lines — cycle initiation, parameter entry, and status monitoring on CNC-adjacent or semi-automatic assembly stations
- Food & Beverage Processing — wash-down-adjacent installations requiring a compact, keypad-driven interface with clear monochrome display readability

Why Engineers Specify This Model
- Proven MicroLogix Ecosystem Fit — native DH-485 communication makes the 2711C-K3M the default HMI pairing for MicroLogix 1000/1100/1400 controllers without additional gateways
- Compact Panel Footprint — 3-inch mono display fits standard cutouts in small enclosures where space is at a premium
- Keypad Reliability in Harsh Environments — no touchscreen glass to crack or degrade; membrane keypad withstands vibration, gloves, and contaminated environments
- Low Total Cost of Ownership — simple programming via PanelBuilder 300 software, minimal maintenance, and long field service life reduce lifecycle costs
- NEMA 4/4X Rating — suitable for wash-down and dust-laden environments without additional enclosure upgrades
- Established Spare Parts Availability — widely stocked globally, reducing downtime risk for maintenance teams managing aging MicroLogix-based lines

Application-Specific FAQ
Q: Is the 2711C-K3M compatible with CompactLogix or ControlLogix PLCs?
A: The 2711C-K3M communicates via DH-485 and RS-232, which are native to MicroLogix platforms. CompactLogix and ControlLogix use EtherNet/IP as their primary HMI protocol. For those platforms, a PanelView Plus or PanelView 800 series terminal is recommended. A protocol converter (e.g., ProSoft MVI46) can bridge DH-485 to ControlNet/EtherNet/IP in legacy retrofit scenarios.
Q: Can I use PanelBuilder 300 on Windows 10/11?
A: PanelBuilder 300 is a legacy application designed for Windows XP/7. Running it on Windows 10/11 typically requires compatibility mode or a virtual machine (VMware/VirtualBox with a Windows XP image). Rockwell Automation does not officially support PanelBuilder 300 on Windows 10/11.
Q: What is the difference between 2711C-K3M and 2711C-T3M?
A: The 2711C-K3M is the keypad-only variant; the 2711C-T3M is the touchscreen variant of the same PanelView C300 platform. Both share the same 3-inch mono display and DH-485 communication. Choose the keypad model for gloved-hand or high-vibration environments; choose the touchscreen model where graphical navigation is preferred.
Q: Is a replacement backlight or display available?
A: The PanelView C300 uses an LCD panel without a user-replaceable backlight in the field. Display replacement requires depot-level repair. Konmask.com can advise on repair service options or provide a replacement unit — contact us for details.
Q: What warranty applies to this unit?
A: Warranty terms depend on the condition of the unit as stated in the listing (new surplus, refurbished, or used). Please refer to the listing condition notes or contact support@konmask.com for specific warranty terms before purchase.
