2711P-RN15C | PanelView Plus ControlNet Communication Module | Allen-Bradley

Module Overview

The 2711P-RN15C is a specialized ControlNet communication interface module designed for the Allen-Bradley PanelView Plus 400 and 600 terminal series. This module allows compact HMI terminals to integrate directly into a ControlNet network, enabling high-speed, deterministic data exchange with Logix5000 controllers. Although officially discontinued by the manufacturer in 2013, the 2711P-RN15C remains a vital component for maintaining legacy industrial networks where scheduled, repeatable communication is required for machine-level visualization.

Detailed Engineering Specifications

The 2711P-RN15C is a field-installable back-module that expands the connectivity of the smaller PanelView Plus units.

• Operating Temperature: 0°C to 55°C (32°F to 131°F)

Network Architecture and ControlNet Benefits

ControlNet is a "scheduled" network, meaning it guarantees that critical data is delivered at a specific, repeatable time interval. By adding the 2711P-RN15C to a PanelView Plus terminal, engineers can ensure that HMI pushbuttons and alarms are synchronized with the PLC scan. This is particularly important in high-speed coordinated motion or safety-monitoring applications where Ethernet latency might be unpredictable. The module supports both redundant and non-redundant media configurations depending on the terminal's physical port layout.

Installation and Maintenance

Since this module was discontinued over a decade ago, maintenance usually involves firmware management and physical connection integrity. The 2711P-RN15C must be firmly seated into the expansion slot on the rear of the PanelView Plus 400/600. Once installed, the terminal’s RSLinx Enterprise (FactoryTalk Linx) configuration must be updated to recognize the ControlNet node address, ensuring the HMI can browse the network and reference tags in the controller.

Technical FAQ

Can I use the 2711P-RN15C with a PanelView Plus 7 terminal?

No. The 2711P-RN15C is strictly designed for the legacy PanelView Plus 400 and 600 (Series A-F). PanelView Plus 7 terminals use different internal architectures and typically rely on EtherNet/IP for communication.

Does this module require a separate power supply?

No. The 2711P-RN15C draws all necessary power directly from the HMI terminal's internal expansion bus.

What is the maximum distance for a ControlNet segment using this module?

Using standard RG-6 coaxial cable, a segment can reach up to 1,000 meters (3,280 feet) without repeaters. If your HMI is located further away, ControlNet repeaters or fiber optic media converters would be required.
