Product Overview

The 1756-CNB is a ControlLogix ControlNet communication module used in legacy industrial control networks. It supports deterministic communication between ControlLogix controllers, I/O systems, and connected industrial devices in plants that still operate with ControlNet infrastructure.

Main Features

ControlNet communication module for ControlLogix systems
Supports legacy deterministic industrial network communication
Used for controller, I/O, and plant network integration
Suitable for maintenance replacement in aging ControlNet systems
Useful for legacy system support and migration planning

Technical Specifications

Model	1756-CNB
Product Type	ControlNet Communication Module
Platform	ControlLogix
Network	ControlNet
Function	ControlNet Bridge Communication
Application	Legacy ControlNet Network Maintenance

Compatible System and Chassis Use

The 1756-CNB is used in ControlLogix chassis systems requiring ControlNet communication. Final compatibility should be confirmed according to the installed controller, chassis, firmware level, network node configuration, and existing ControlNet layout.

Industrial Applications

This module is used in process control systems, production lines, material handling systems, packaging machinery, and other industrial installations where ControlNet communication remains part of the control architecture.

Maintenance and Replacement Notes

The 1756-CNB is often needed for legacy ControlNet maintenance. It is suitable for replacement projects where network communication loss may cause production downtime, and it can support continued operation while a migration plan is prepared.
