Information About 1756-EN4TR

The 1756-EN4TR is part of the Allen-Bradley ControlLogix 1756 EtherNet/IP communication module family, designed to provide robust connectivity and diagnostics in demanding environments. It operates as a bridge for I/O, controller-to-controller, and information data exchange over EtherNet/IP networks. With four embedded Ethernet ports, it offers flexibility in designing linear, star, and ring topologies, including DLR for sub-3 ms fault recovery. The module supports high-speed communication with up to 256 TCP/IP connections, enabling large data throughput for complex systems. Integration with Studio 5000 Logix Designer and FactoryTalk software provides configuration, diagnostics, and monitoring directly within the control system. Built-in web server, extensive CIP support, and LED indicators improve visibility and simplify troubleshooting.

Key Features:

  • Design: High-performance EtherNet/IP module for ControlLogix systems.
  • Ports: Four RJ-45 10/100/1000 Mbps Ethernet ports with integrated switching.
  • Connections: Supports up to 256 TCP/IP connections for large systems.
  • Topology Support: Enables star, linear, and Device Level Ring (DLR) network designs.
  • Redundancy: Provides high availability with fast network recovery (<3 ms on DLR).
  • Integration: Seamless setup and monitoring via Studio 5000 and FactoryTalk.
  • Diagnostics: Built-in web server, CIP messaging, and LED indicators for troubleshooting.
  • Application Range: Ideal for process automation, safety-critical networks, and large-scale manufacturing systems.

The 1756-EN4TR delivers the redundancy, bandwidth, and reliability required for high-performance EtherNet/IP communication in modern industrial automation systems.
