More Information

Overview Manuals Operator Interface DH-485 Network Installation Product Applications

Features:

  • Terminal family: PanelView Standard 550 keypad HMI.
  • Network: DH-485 communication.
  • Power: 24 V DC version identified by the L1 suffix.
The stored PanelBuilder32 project defines the machine screens, alarms and keypad actions.

DH-485 addressing, cable layout and DC supply polarity establish the installed configuration.

Migration can require network conversion, panel adaptation and application changes on the replacement platform.

Apter Power supports exact-catalog and migration review for the Allen-Bradley 2711-K5A3L1 PanelView 550 Terminal.

  • Uses a 5.5-inch monochrome display for application-defined text and graphics.
  • Accepts operator navigation and machine commands through the keypad.
  • Runs the alarm, status and control objects retained in the HMI project.
  • Connects to the installed control system through DH-485.
  • Requires node addressing and cable layout to be preserved.
  • May need an approved conversion method when the replacement HMI lacks native DH-485.
  • Uses 24 V DC power as identified by the L1 suffix.
  • Requires application backup and connection records before removal.
  • Verify panel opening, DC polarity and adapter requirements before replacement.
  • Operator interface on legacy DH-485 machine networks.
  • Local presentation of process status, alarms and command screens.
  • Maintenance replacement where the original application and network record are available.
Description
On established DH-485 machine networks, 2711-K5A3L1 presents the PanelView 550 application on a 5.5-inch monochrome display and accepts commands through its keypad. The project determines the status pages, alarm messages and operating controls available at the station.

Electrical fit depends on more than the enclosure: 2711-K5A3L1 combines DH-485 communication with 24 V DC power indicated by the L1 suffix. Node addressing, network cabling and supply polarity must therefore match the installed system.

Service work should begin with an application backup because 2711-K5A3L1 is discontinued by the OEM. Record the DH-485 configuration and panel dimensions before choosing a replacement terminal, converter or adapter plate.

Technical notes
Before removing 2711-K5A3L1, upload the PanelView application and document DH-485 addressing, cable routing, connector pinout and DC power polarity. Verify the panel cutout and keypad-terminal format. Replacement with a newer platform can involve a network converter, adapter plate and application conversion, so plan the migration as a system change.

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.
A DH-485 node is missing after 2711-K5A3L1 is installed; what should commissioning verify?
Verify the node address, baud rate, cabling, shield practice, and termination against the approved DH-485 network drawing. Local screen operation does not confirm successful network participation.
Intermittent network faults began after adding 2711-K5A3L1; could a duplicate address be responsible?
Yes. Compare the terminal address with every active DH-485 node and assign a unique value if a conflict exists. Then clear and retest the network rather than treating the symptom as a display fault.
Why might 2711-K5A3L1 reboot when nearby contactors operate?
Check the 24 V DC source at the terminal during the switching event, including polarity, common reference, protective device, and conductor voltage drop. Separate supply instability from communication or application problems.
How should an approved application be restored to 2711-K5A3L1?
Use the controlled PanelBuilder32 project and a compatible ATA memory card or the documented transfer connection. Keep the pre-service backup and validate navigation, live data, alarms, and communication after loading.
The screen is correct but a function key opens the wrong page; what should be reviewed on 2711-K5A3L1?
Compare the running file with the approved project and inspect that key’s configured action. If the assignment is correct, test the keypad for a physical fault before replacing the whole operator terminal.
How should incorrect alarm timestamps on 2711-K5A3L1 be handled after long storage?
Set the real-time clock, inspect its backup source according to the service instructions, and power-cycle the unit. Use alarm history for diagnosis only after the clock retains the correct date and time.
