More Information

Overview Manuals Keypad Operation Network & Serial Panel Fit Product Applications

Features:

  • 3.8-inch grayscale PanelView Plus 400 display.
  • Keypad-only operator input for physical navigation.
  • EtherNet/IP and RS-232 communication with 24 V DC power.
The compact 400 format serves installations where panel space and tactile key operation are part of the machine design.

Its application must expose required commands through function and navigation keys because the terminal has no touch interface.

Service work should retain the controller path, key map and small panel opening as one installed configuration.

Apter Power supports document review, exact-model quotation and procurement for the Allen-Bradley 2711P-K4M20D PanelView Plus 400 Keypad Grayscale Terminal.

All prices are shown in USD.
  • All operator entry is performed through physical keys.
  • Function-key assignments come from the loaded runtime application.
  • Navigation and numeric entry must remain usable without touch targets.
  • Acceptance testing should include every machine-critical programmed key.
  • EtherNet/IP can carry the application controller path.
  • RS-232 can serve the serial connection defined by the project.
  • The replacement terminal must receive the recorded address and shortcut settings.
  • A powered screen does not prove that either communication route is correct.
  • The compact PanelView Plus 400 opening differs from 600-size terminals.
  • Mounting hardware and rear clearance must match the installed enclosure.
  • The 24 V DC source and protective earth must be retained.
  • A larger terminal requires deliberate panel and operator-workflow redesign.
  • Compact machine panels using keypad-driven HMI navigation.
  • Legacy PanelView Plus 400 maintenance and replacement planning.
  • Small operator stations connected by EtherNet/IP or RS-232.
Description
Compact machine panels that rely on physical keys can use 2711P-K4M20D as a grayscale PanelView Plus 400 operator terminal. Its small format keeps the interface focused on programmed function keys and directional navigation rather than touch interaction.

The application loaded into 2711P-K4M20D can communicate over EtherNet/IP or RS-232, so a service replacement must preserve the controller route as well as the key assignments. A powered display alone does not prove that the runtime is talking to the machine.

Because 2711P-K4M20D belongs to the original PanelView Plus generation, its panel opening, 24 V DC supply and runtime environment must be treated as an installed set. A larger 600 terminal changes the mechanical fit and operator workflow even when the family name is similar.

Technical notes
2711P-K4M20D uses a 3.8-inch grayscale display, keypad input, EtherNet/IP, RS-232 and DC power. Its display size must not be published as 5.5 or 5.7 inches. Treat it as a first-generation PanelView Plus terminal and retain the runtime and communication configuration before service.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
When should a panel builder retain 2711P-K4M20D instead of fitting a larger terminal?
Retain it when the existing opening and machine design are built around the compact PanelView Plus 400 keypad format; a larger terminal requires a new mechanical and operator-interface review.
Can an operator use touch commands on 2711P-K4M20D after a project transfer?
No. The terminal is keypad-operated, so the project must expose all required navigation and entry through its physical keys.
What should be archived before a maintenance team removes 2711P-K4M20D?
Archive the runtime, communication shortcuts, terminal settings and machine-specific key map so the replacement can reproduce the installed workflow.
Where should a technician start if 2711P-K4M20D displays screens but no process data?
Follow the communication method selected by the project: verify the EtherNet/IP address and controller path, or the RS-232 configuration and cable.
What electrical checks belong in the installation record for 2711P-K4M20D?
Record the 24 V DC polarity, protective earth, connector seating and conductor routing before power is restored.
What must a modernization project preserve when retiring 2711P-K4M20D?
Preserve the key-driven navigation logic, controller links and operator acceptance criteria while addressing application conversion and panel-cutout changes.
