More Information

Overview Manuals Operator Interface Serial Communication Installation Product Applications

Features:

  • Terminal family: PanelView Standard 550 keypad HMI.
  • Serial protocol: RS-232 communication using DF1.
  • Power: 24 V DC version identified by the L1 suffix.
The loaded project determines the machine screens, alarms and keypad actions available to the operator.

DF1 parameters, serial pinout and DC supply polarity form the electrical compatibility boundary.

A newer terminal can require application conversion, rewiring and a mechanical adapter rather than a direct swap.

Apter Power supports exact-catalog and migration review for the Allen-Bradley 2711-K5A16L1 PanelView 550 Terminal.

  • Uses a 5.5-inch monochrome screen for the installed HMI project.
  • Provides tactile navigation and application-defined commands through the keypad.
  • Displays alarms, machine status and operator prompts stored in the terminal.
  • Uses RS-232 with the DF1 protocol.
  • Requires protocol, baud rate and cable pinout to match the controller channel.
  • Allows application transfer through the serial communication arrangement documented for the terminal.
  • Uses 24 V DC power as identified by the L1 suffix.
  • Requires application backup and wiring records before removal.
  • Check the panel opening, adapter plate and cable changes before migration.
  • Operator stations that retain an RS-232 DF1 controller link.
  • Machine panels requiring keypad navigation and monochrome status display.
  • Legacy HMI service where DC power and the original serial project remain available.
Description
When a legacy machine depends on a serial PanelView station, 2711-K5A16L1 provides a 5.5-inch monochrome display and keypad for the stored HMI application. Operator prompts, alarms and command screens come from the project loaded into the terminal.

The suffix and communication code both matter: 2711-K5A16L1 uses 24 V DC power and an RS-232 port configured for DF1. Matching only the PanelView 550 housing can leave the replacement with the wrong protocol or supply arrangement.

Before removal, capture the application and serial parameters because 2711-K5A16L1 belongs to a discontinued product family. Cable pinout, DC polarity and panel geometry should be reviewed together with any proposed migration hardware.

Technical notes
Back up the application from 2711-K5A16L1 and record DF1 protocol settings, serial pinout and DC supply polarity before removal. Confirm the monochrome keypad-terminal format and panel opening. A migration to a newer terminal may require an adapter plate, cable changes and application conversion, so do not assume a drop-in replacement.

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.
An RS-232 DF1 link remains offline after replacing 2711-K5A16L1; what should be compared?
Compare baud rate, parity, error checking, station addressing, handshaking, and connector pinout with the controller channel. Both ends must use the same DF1 settings before the link can exchange data.
Why does 2711-K5A16L1 restart when outputs on the machine switch?
Measure the 24 V DC supply at the terminal under load and check polarity, common reference, protective device, and voltage drop. A supply that appears correct with no load can dip during machine switching and reset the operator terminal.
May a project prepared for a DH-485 serial terminal be loaded into 2711-K5A16L1?
Only after the communication configuration is deliberately converted and validated for DF1. Sharing an RS-232 connector shape does not make the protocols or application communication settings interchangeable.
What is a controlled way to move an application to 2711-K5A16L1 during an outage?
Back up the approved PanelBuilder32 project, use a compatible ATA memory card or documented transfer path, and record the file revision. After loading, verify startup, navigation, controller data, alarms, and retained settings before release.
The keypad response changed after an application reload; how should 2711-K5A16L1 be checked?
Review the project’s function-key assignments and screen navigation first. If they match the approved file, test every physical key and document any intermittent or nonresponsive positions before replacing the terminal.
Event records show the wrong date after 2711-K5A16L1 was powered down for months; what is the next step?
Correct the real-time clock and inspect its backup source in line with the service procedure. Recheck the date after a complete power cycle so subsequent event history is trustworthy.
