1756-CN2R Allen Bradley Communication Bridge Module

Application

High-Availability Production Lines: In industries like automotive, food and beverage, and consumer goods, where downtime is extremely costly, the 1756-CN2R enables redundant communication for critical sections of the production line, ensuring continuous operation even if a communication path fails.

Power Generation and Distribution: In power plants and substations, the 1756-CN2R helps manage critical processes like turbine control, generator synchronization and switchgear operation.

Key Feature

High-Speed, Deterministic Communication: Designed to support the ControlNet network's core strength, delivering predictable and repeatable data exchange regardless of network load. 

ControlLogix Platform Integration: Seamlessly integrates into the ControlLogix chassis, leveraging the platform's modularity and robust backplane for power and data. 

Built-in Diagnostics: Features onboard diagnostics and status indicators (LEDs) to provide real-time feedback on network health and module operation, aiding in quick troubleshooting and maintenance.

Description

The 1756-CN2R handles the complex ControlNet protocol, allowing for scheduled (time-critical) and unscheduled (messaging) data transfers. It plays a vital role in distributed control systems where precise timing and uninterrupted communication are paramount for synchronization and efficient operation. This module helps build robust and resilient control architectures in critical industrial applications.The Allen-Bradley 1756-CN2R is a high-performance ControlNet communication bridge module specifically designed for use within Rockwell Automation's ControlLogix programmable automation controllers (PACs).
