Description
Additional information

The Allen-Bradley 2711-KC1 is a DH-485/RS-232 communication module designed for use with the PanelView 550 series of operator terminals manufactured by Rockwell Automation (Allen-Bradley). This module serves as a plug-in communication interface card that enables the PanelView 550 terminal to connect to Allen-Bradley programmable logic controllers and other compatible devices over DH-485 and RS-232 networks. It is a key component for integrating PanelView 550 terminals into existing Allen-Bradley control system architectures.

The 2711-KC1 communication module supports the DH-485 token-passing network protocol, which allows multi-drop communication with up to 32 nodes on a single network segment. The RS-232 port provides point-to-point serial communication capability for direct PLC connections or programming interfaces. The module is designed to plug directly into the communication slot of the PanelView 550 terminal, requiring no external power supply. It supports communication with Allen-Bradley SLC 500, MicroLogix, and compatible PLC families using DF1 and DH-485 protocols.

The 2711-KC1 is commonly used in discrete manufacturing, material handling, packaging, and process control applications where PanelView 550 operator terminals are integrated with Allen-Bradley SLC 500 or MicroLogix PLC systems. It is well suited for retrofit and upgrade projects where existing PanelView 550 terminals require a replacement or additional communication module. The module is also used in food and beverage, automotive assembly, and general industrial automation environments where reliable HMI-to-PLC communication is essential.

Common Communication Error Codes & Diagnostics

Comm Error: Communication failure between the PanelView terminal and the connected PLC over DH-485 or RS-232.
Verify network cabling and termination resistors. Check node address settings and baud rate configuration on both the terminal and PLC. Inspect the 2711-KC1 module seating in the communication slot.
No Communication: Terminal displays 'No Communication' indicating loss of connection to the target PLC.
Check RS-232 or DH-485 cable integrity and connections. Confirm PLC is powered and in Run or Remote Run mode. Verify the communication module is properly seated and the correct driver is selected in the terminal configuration.
Timeout Error: Communication timeout occurred; the terminal did not receive a response from the PLC within the expected time window.
Reduce network traffic or number of nodes on the DH-485 network. Increase the communication timeout value in the terminal configuration. Check for cable faults or excessive cable length exceeding DH-485 specifications.
Invalid Address: The terminal attempted to access a data file address that does not exist or is out of range in the connected PLC.
Review the PanelView application file and verify all configured data addresses exist in the PLC program. Correct any mismatched or invalid tag addresses using PanelBuilder software.
Module Not Detected: The PanelView 550 terminal does not recognize the installed 2711-KC1 communication module.
Power down the terminal and reseat the 2711-KC1 module firmly in the communication slot. Inspect the module connector pins for damage or contamination. Replace the module if the terminal still fails to detect it after reseating.
Baud Rate Mismatch: The configured baud rate on the terminal does not match the baud rate set on the PLC or network.
Access the terminal configuration menu and set the baud rate to match the PLC or DH-485 network setting (typically 19200 bps for DH-485). Ensure all nodes on the DH-485 network use the same baud rate.

Frequently Asked Questions

What PLC families are compatible with the 2711-KC1 communication module?

The 2711-KC1 supports communication with Allen-Bradley SLC 500 and MicroLogix PLC families using DH-485 and DF1 (RS-232) protocols. It is not designed for EtherNet/IP or ControlNet communication.

What communication protocols does the 2711-KC1 support?

The module supports the DH-485 token-passing network protocol and DF1 full-duplex or half-duplex protocol over the RS-232 serial interface.

Can the 2711-KC1 be used with PanelView terminals other than the PanelView 550?

The 2711-KC1 is specifically designed for the PanelView 550 series terminals. It is not interchangeable with communication modules from other PanelView series such as the PanelView 600 or PanelView 1000.

What software is used to configure applications for the PanelView 550 with this module?

PanelBuilder 1400e software is used to create and download application files to the PanelView 550 terminal. The communication driver and PLC address settings are configured within the PanelBuilder application.

What is the maximum number of nodes supported on a DH-485 network using the 2711-KC1?

The DH-485 network supports a maximum of 32 nodes per network segment, including the PanelView 550 terminal and all connected PLC and peripheral devices.

Troubleshooting

PanelView 550 displays 'No Communication' after installing the 2711-KC1 module

Verify the module is fully seated in the communication slot. Check that the correct communication driver (DH-485 or RS-232 DF1) is selected in the terminal configuration menu. Inspect the network cable for continuity and correct wiring.

Reseat the 2711-KC1 module with the terminal powered off. Confirm the driver selection matches the physical connection type. Replace the communication cable if continuity testing reveals a fault. If the issue persists, substitute the 2711-KC1 with a known-good module to isolate the fault.

Intermittent communication dropouts on the DH-485 network

Check the DH-485 network for missing or incorrect termination resistors at the network endpoints. Measure cable length to ensure it does not exceed the DH-485 maximum of 1219 m (4000 ft). Verify that all nodes are configured with unique node addresses and the same baud rate.

Install 120-ohm termination resistors at both ends of the DH-485 network if not already present. Reduce cable length or add a repeater if the network exceeds the maximum distance. Correct any duplicate node addresses in the network configuration.

Terminal application fails to download from PanelBuilder software via RS-232

Confirm the RS-232 cable is a null-modem (crossover) cable and is connected to the correct port on the 2711-KC1 module. Check the COM port settings in PanelBuilder match the terminal baud rate and communication parameters.

Replace the RS-232 cable with a verified null-modem cable. Set the baud rate in PanelBuilder and on the terminal to the same value (typically 19200 bps). Ensure no other software application is using the PC COM port during the download process.

PanelView 550 terminal does not recognize the 2711-KC1 module after installation

Inspect the module connector and the terminal communication slot for bent pins, debris, or corrosion. Confirm the module part number matches the required communication type for the installed application.

Clean the connector contacts with isopropyl alcohol and a lint-free swab. Straighten any bent connector pins carefully. If the terminal still does not detect the module, replace the 2711-KC1 with a new or refurbished unit.

Data values displayed on the PanelView 550 are incorrect or not updating

Verify the PLC data file addresses configured in the PanelBuilder application match the actual data file structure in the PLC program. Check that the PLC is in Run mode and the data files being referenced are not write-protected.

Compare the PanelBuilder application tag addresses against the PLC program data files and correct any mismatches. Re-download the corrected application to the terminal. Confirm the PLC program is actively writing to the referenced data addresses during operation.
