Allen-Bradley 1756-CNBR | ControlNet Communication Bridge Module with Redundant Media Support
Overview
The Allen-Bradley 1756-CNBR is a ControlNet communication bridge module designed for use in ControlLogix systems. It supports redundant coaxial media for increased network reliability and enables high-speed communication between ControlLogix controllers and other devices over ControlNet networks. Installed into a ControlLogix chassis, the 1756-CNBR allows deterministic data transfer, peer-to-peer messaging, and real-time control in distributed automation systems.
Key Features

-
Redundancy: Supports redundant coaxial media (A and B channels)
-
Backplane Communication: Interfaces with ControlLogix chassis via high-speed backplane
-
Real-Time Performance: Deterministic and repeatable network timing
-
Status Indicators: LED diagnostics for channel and module status
-
Mounting: Standard ControlLogix chassis slot (right-side placement)
-
Integration: Fully supported in Studio 5000 and RSLogix 5000 environments
-
Application Flexibility: Suitable for peer-to-peer and distributed control architectures
