Allen-Bradley 1756-EN2TR ControlLogix EtherNet/IP Module | DLR Supported

Description

【Product Overview】

The Allen-Bradley 1756-EN2TR is a high-performance ControlLogix EtherNet/IP Communication Module designed to provide high-speed, deterministic networking for mission-critical automation systems.

Featuring Dual RJ45 Ports, this module is specifically engineered to support Device Level Ring (DLR) topologies, providing superior network resiliency and cable redundancy. Whether you are connecting remote I/O racks, synchronizing high-speed motion drives, or interfacing with plant-wide SCADA systems, the 1756-EN2TR acts as the high-capacity bridge for your data. With support for up to 256 Logix connections and 128 TCP/IP connections, it is the standard choice for modernizing ControlLogix architectures where high availability and rapid data throughput are mandatory.

【Technical Specifications】

【Key Features】

(1) Dual-Port Redundancy: Two integrated Ethernet ports allow for Series/Linear or Device Level Ring (DLR) configurations, ensuring the network remains operational even if one cable is severed.

(2) High-Speed Throughput: Optimized for high-density data exchange, supporting CIP (Common Industrial Protocol) safety and motion applications over EtherNet/IP.

(3) Deterministic Communication: Provides prioritized messaging and time synchronization (IEEE 1588) for precision-sensitive industrial processes.

(4) Advanced Diagnostics: Built-in web server and scrolling front-panel display provide real-time status of IP addresses, link speeds, and network health.

(5) Integrated Security: Features secure firmware capabilities and port control to help protect against unauthorized network access.

(6) No Configuration Jumpers: All configuration is handled through RSLogix 5000 or Studio 5000 software, making installation and replacement seamless.

【Applications】

(1) Distributed I/O Systems: Coordinating communication between a central ControlLogix chassis and multiple remote 1756 or 1794 (FLEX) I/O racks.

(2) High-Availability Networks: Implementing DLR rings in critical infrastructure like water treatment or automotive assembly lines to prevent downtime.

(3) Motion Control: Synchronizing Kinetix servo drives and motion-heavy machinery over an integrated EtherNet/IP backbone.

(4) HMI/SCADA Integration: Providing a high-bandwidth gateway for factory-floor data to reach upper-level monitoring and MES systems.

(5) System Modernization: Replacing older 1756-ENBT or 1756-EN2T modules to gain port redundancy and higher connection counts.
