It can be installed in any ControlLogix chassis and is compatible with RSLogix 5000 and Studio 5000 software versions 20 and later. The module supports both star and device-level ring (DLR) network topologies, providing flexibility in network design and redundancy. With its robust construction and reliable performance, the 1756-EN2TR is a trusted choice for industrial automation professionals seeking to enhance their network infrastructure. The Allen-Bradley 1756-EN2TR is a high-performance EtherNet/IP communication bridge module designed for the ControlLogix platform. Basic Product Information Supports up to 256 TCP/IP connections and 128 CIP connections High-speed 1.6 GHz processor for fast data exchange Supports Device Level Ring (DLR) for network redundancy Advanced network security with port filtering and protocol restrictions Compatible with RSLogix 5000 and Studio 5000 (v20 or later) Dual Gigabit Ethernet ports (10/100/1000 Mbps) with copper RJ45 connectors Technical Specifications Version & Model Difference The 1756-EN2TR is part of the ControlLogix EtherNet/IP bridge family. Compared to earlier models like the 1756-ENBT (10/100 Mbps) and 1756-EN2T (single port), the EN2TR offers dual Gigabit ports and a faster processor, enabling higher data throughput and support for more connections. It also adds DLR capability for resilient ring topologies. The 1756-EN2TR is the preferred choice for new installations requiring high performance and redundancy. Application Scenarios Can the 1756-EN2TR be used in a redundant system? Yes, the 1756-EN2TR supports DLR, which allows for network redundancy in ring topologies. For controller redundancy, you can use two EN2TR modules in a redundant chassis configuration. What software is required to configure the 1756-EN2TR? You need RSLogix 5000 or Studio 5000 Logix Designer version 20 or later. The module can be configured via the I/O tree in the software, and its IP address can be set using BOOTP/DHCP or the module's web interface. Is the 1756-EN2TR compatible with older ControlLogix processors like L61? Yes, the 1756-EN2TR is compatible with ControlLogix L6x and L7x processors, provided the firmware and software versions are updated to meet the module's requirements. Check the Rockwell Automation compatibility matrix for exact firmware versions. What is the difference between 1756-EN2T and 1756-EN2TR? The 1756-EN2T has a single Ethernet port, while the 1756-EN2TR has two ports. The EN2TR supports Device Level Ring (DLR) topology for redundancy, whereas the EN2T does not. Both support Gigabit speeds and have similar connection limits.
