Rockwell’s PanelView Standard documentation groups 2711-K6C15 with the PanelView 600 color keypad terminals and identifies the model as a ControlNet version. The same documentation gives a 320 × 234 display resolution, 240 KB nonvolatile memory, and 85–264 VAC input capability for the applicable 2711-K6C family.
One catalog detail deserves attention: the terminal is commonly described as a “5-inch” or “6-inch” display depending on the source. Rockwell’s technical table gives a 115 × 86 mm viewing area and 320 × 234 resolution, while product listings commonly call it a 5-inch display. Use the Rockwell dimensions and catalog number for engineering identification rather than relying on screen-size terminology alone.
Application Scenarios & Pain Points
An obsolete HMI can be harder to replace than the PLC behind it. The real constraint is often the existing application file, communication protocol, and panel cutout—not simply finding a screen that turns on.
- ControlNet machine interfaces: The 2711-K6C15 is specifically configured for ControlNet communication, making it suitable for legacy machines whose controller network still uses ControlNet.
- Process and machine operator stations: Operators can monitor process values, alarms, status information, and issue commands through the keypad-based interface.
- Legacy Rockwell PLC systems: It can remain relevant where an installed PanelView Standard application has not yet been migrated to a newer HMI platform.
- Emergency replacement: A tested spare can reduce the risk associated with a failed display, keypad, or aging internal electronics.
Field note: Before replacing the terminal, save the existing application if the old unit still boots. A replacement HMI is only half the job; recovering the correct application, communication configuration, and node settings can take longer than mounting the hardware.

- Allen-Bradley 2711-K6C20 — PanelView 600 color keypad terminal with EtherNet/IP rather than ControlNet. It may suit a migration to Ethernet, but it is not a protocol-equivalent replacement for K6C15.
- Allen-Bradley 2711-K6C16 — PanelView 600 keypad model using RS-232/DF1 communication. Useful for systems built around DF1 rather than ControlNet.
- Allen-Bradley 2711-K6C10 — PanelView 600 keypad terminal configured for DeviceNet. It belongs to the same terminal family but uses a different communication architecture.
- Allen-Bradley 2711-K6C8 — PanelView 600 keypad model for DH+ applications. Relevant to older Allen-Bradley networks where Data Highway Plus remains in service.
- Allen-Bradley 2711-K6C1 — PanelView 600 keypad model for Remote I/O. It is a different network variant and should not be substituted for a ControlNet terminal.
- Allen-Bradley 2711-NL3 — Replacement backlight associated with applicable PanelView 600 terminals. The backlight is a service component rather than an HMI replacement.
- Allen-Bradley 2711-NC14 — Communication cable identified with the 2711-K6C15 in available product documentation. Verify the actual connector and communication requirement before ordering.
- Allen-Bradley PanelView 600 family — The broader terminal family includes DH-485, Remote I/O, DH+, DeviceNet, ControlNet, DF1, and EtherNet/IP variants. The final digit of the catalog number is therefore significant when selecting a replacement.
The Engineer’s Guide: Field Pitfalls to Avoid
⚠️ Do not replace K6C15 with another PanelView 600 just because the cutout matches.
The PanelView 600 family contains multiple communication variants. is the ControlNet version; K6C8, K6C10, K6C16, and K6C20 use different communications.
How to avoid it: Match the complete catalog number and verify the controller network before installation.
⚠️ Check the power requirement carefully.
The is documented as an 85–264 VAC terminal. Do not assume that every PanelView 600 uses the same power input; versions ending in L1 are associated with DC-powered configurations.
How to avoid it: Check the nameplate and existing cabinet supply before energizing the replacement.
⚠️ Firmware and application compatibility can become the real problem.
Available documentation identifies PanelBuilder32 as the software environment, while secondary references report firmware ranges extending through 4.48.
How to avoid it: Record the existing terminal’s firmware revision and application version before removing it. If the old unit still operates, back up the application first.
Frequently Asked Questions (FAQ)
What is Allen-Bradley 2711-?
It is an Allen-Bradley PanelView Standard 600 color operator terminal with a physical keypad and ControlNet communications. It provides the HMI layer between machine operators and the underlying control system.
Is 2711- a touchscreen HMI?
The is primarily a keypad terminal, not the keypad/touch version. Rockwell’s documentation distinguishes the K6C and T6C configurations, with K6C models using the keypad-oriented configuration.
Does 2711- support ControlNet?
Yes. ControlNet is the defining network option for the catalog number. Rockwell’s PanelView Standard table explicitly lists 2711- under the ControlNet communication variant.
What power supply does 2711- require?
The documented AC version accepts 85–264 VAC at 47–63 Hz, with maximum power consumption of approximately 60 VA.
Can I replace 2711- with a 2711-K6C20?
Not as a direct protocol-equivalent replacement. uses ControlNet, while K6C20 uses EtherNet/IP. The physical family may be similar, but the communication architecture and application configuration are different.
Is the 2711- still manufactured?
Current equipment references identify the model as discontinued/obsolete. For an existing machine, procurement should therefore focus on exact catalog number, series/revision, tested condition, display/backlight condition, and application compatibility.
What should I verify when buying a used 2711-?
Request confirmation of:
- Exact catalog number.
- Series and revision.
- Firmware revision.
- ControlNet communication operation.
- Display brightness and dead-pixel condition.
- All keypad/function-key operation.
- Power-up diagnostics.
- Application-memory status.
