Product Overview

1756-EN2TR is a ControlLogix EtherNet/IP bridge module used for industrial Ethernet communication, PLC network integration, production line automation, and factory maintenance replacement. It is commonly selected for systems where the communication module must support a more flexible Ethernet topology than a single-port bridge module.

This model is suitable for ControlLogix 1756 systems that need network communication between PLC controllers, remote I/O, operator interfaces, drives, industrial switches, and plant-level control systems. In maintenance projects, 1756-EN2TR is often requested when a dual-port communication module is installed in the existing chassis and the replacement must match the original network architecture.

Main Features

• ControlLogix 1756 series EtherNet/IP communication module
• Designed for industrial Ethernet network integration
• Suitable for systems requiring dual-port network support
• Used for controller communication, remote I/O, HMI, and drive integration
• Important spare part for PLC network maintenance and system repair

Technical Specifications

Compatible System and Chassis Use

1756-EN2TR is installed in ControlLogix 1756 chassis systems. It should be checked together with the installed controller, power supply, communication topology, Ethernet cabling, industrial switches, firmware revision, and PLC project settings. If the original system uses a ring or dual-port network arrangement, the replacement module should match the installed communication design.

Industrial Applications

This module is used in manufacturing production lines, material handling systems, process control cabinets, packaging machines, water treatment systems, plant utilities, remote I/O networks, and industrial automation systems requiring reliable Ethernet communication.

Maintenance and Replacement Notes

Before replacing 1756-EN2TR, confirm the complete catalog number, firmware level, IP address, network topology, chassis slot, communication load, and original nameplate. Communication issues may also be caused by switches, cables, duplicate IP addresses, topology faults, or incorrect project configuration.
