1756-EN3TR ControlLogix EtherNet/IP Communication Module 1 Gbps

Product Overview

1756-EN3TR is a ControlLogix EtherNet/IP bridge module for high-capacity industrial network communication, PLC system integration, production line automation, and factory maintenance replacement. It is designed for ControlLogix 1756 systems where Ethernet communication performance, network capacity, and reliable controller connectivity are important for machine or process operation.

This module is suitable for users who need a communication bridge for larger PLC systems, remote I/O communication, HMI data exchange, drive communication, and plant-level Ethernet integration. It is often used in system upgrade or replacement projects where the installed module and communication load must be checked carefully before ordering.

Technical Specifications

Compatible System and Chassis Use

1756-EN3TR is used in ControlLogix 1756 chassis systems with PLC controllers, I/O modules, power supplies, and other network components. Before replacement, users should confirm firmware revision, chassis slot, network topology, IP settings, communication load, project configuration, and compatibility with the installed controller system.

Industrial Applications

This communication module is used in large manufacturing systems, process automation cabinets, remote I/O networks, material handling lines, packaging systems, utility control panels, production monitoring systems, and industrial Ethernet networks. It supports communication between PLC controllers and other automation devices within the plant control architecture.

Maintenance and Replacement Notes

Network module replacement should not be done only by matching the physical appearance. Users should verify the exact catalog number, firmware version, IP configuration, network capacity requirement, topology, chassis compatibility, and original product label. Communication faults may also come from external switches, cables, configuration errors, or overloaded network traffic.
