1756-CN2 ControlLogix ControlNet Communication Module

Product Overview

The 1756-CN2 is a ControlLogix ControlNet communication module used for industrial network communication in ControlLogix automation systems. It is commonly used in mature ControlNet installations where stable controller-to-I/O and controller-to-device communication is required.

Main Features

• ControlNet communication module for ControlLogix systems
• Supports industrial ControlNet network integration
• Used for controller, I/O, and device communication
• Suitable for mature system maintenance and spare parts replacement
• Useful for downtime recovery and legacy network support

Technical Specifications

Compatible System and Chassis Use

The 1756-CN2 is installed in a ControlLogix chassis for ControlNet communication. Final compatibility should be checked according to the installed processor, chassis, firmware revision, node count, network schedule, and existing ControlNet architecture.

Industrial Applications

This module is used in manufacturing lines, process control systems, packaging machines, material handling systems, and industrial plants where ControlNet communication is still part of the automation network.

Maintenance and Replacement Notes

The 1756-CN2 is commonly used for maintenance replacement in mature ControlLogix systems. It supports legacy network continuity and helps reduce downtime when an existing ControlNet communication module needs replacement.
