A-B 1756-CNBR,also known as the control bridge redundancy module,is a network communication module produced by Allen-Bradley.The following is a detailed introduction to the module:

I.Product Overview

The A-B 1756-CNBR module is an important component of the ControlLogix system.It is mainly used to realize network communication between the ControlLogix controller and other devices.The module has redundancy function,which can enhance the reliability and stability of the system.

II.Technical Specifications

Port Configuration:

Two control network BNC ports(the ordinary 1756-CNB module has only one)

One control network RJ45 port

Supported media:redundant media

Data processing capacity:

Can handle up to 64 bidirectional scheduled and unscheduled connections with other ControlNet devices

Support 99 available nodes at the same time

Communication interface:It has Ethernet interface,control network interface,etc.to realize data exchange and communication with other devices and systems.

High-performance processing capability:Equipped with a high-performance processor,it can handle complex control algorithms and real-time tasks to meet the requirements of industrial automation systems.

Programmability:With programmability,parameters can be set and functions customized through programming or configuration software to meet different application requirements.

III.Product Features

Redundancy function:With two control network BNC ports,the A-B 1756-CNBR module supports redundant connections,thereby improving the reliability and stability of network communication.When one of the ports fails,the other port can take over the communication task to ensure the continuous operation of the system.

Compatibility:The module is compatible with other automation products and systems of AB Company,and can form a complete automation control system with other modules.This provides users with more flexible system configuration and integration options.

Multiple communication interfaces:Through Ethernet interface and control network interface,the A-B 1756-CNBR module can exchange data and communicate with other devices and systems.This provides users with a wider range of connection options and higher communication flexibility.

High-performance processing capability:The module is equipped with a high-performance processor that can handle complex control algorithms and real-time tasks.This ensures the response speed and accuracy of the industrial automation system and improves production efficiency and quality.

Programmability:Through programming or configuration software,users can set parameters and customize functions for the A-B 1756-CNBR module.This provides users with more flexible control options and higher system adaptability.
