1756-EN2TR Allen Bradley ControlLogix Ethernet Module DLR Topology Support
The Allen-Bradley 1756-EN2TR is a high-performance, dual-port EtherNet/IP™ communication module designed for the ControlLogix® programmable automation controller (PAC) platform. Engineered for mission-critical applications requiring network redundancy and seamless data exchange, this module enables linear or Device Level Ring (DLR) topologies to ensure continuous operation in the event of a network cable failure—making it ideal for automotive, oil & gas, power generation, water/wastewater, and other industries where uptime is essential.
Featuring two independent 10/100 Mbps Ethernet ports, integrated switch functionality, and support for CIP Sync, CIP Motion, and CIP Safety, the 1756-EN2TR delivers deterministic, real-time control over standard Ethernet infrastructure. It seamlessly integrates with Studio 5000 Logix Designer®, Rockwell Automation’s engineering environment, and supports producer/consumer architecture, allowing multiple controllers and HMIs to share I/O and messaging data efficiently across the network.
