1788-EN2DNR Allen-Bradley | 2-Port Redundant DeviceNet Gateway

Allen-Bradley 1788-EN2DNR Series A EtherNet/IP to DeviceNet Linking Device

Product Overview

The 1788-EN2DNR (Series A) is a high-availability linking device manufactured by Rockwell Automation, designed to serve as a mission-critical bridge between EtherNet/IP and DeviceNet networks. By acting as a gateway, it enables ControlLogix and CompactLogix controllers to scan, configure, and control up to 63 DeviceNet nodes over an Ethernet backbone. Unlike standard linking devices, the 1788-EN2DNR features dual Ethernet ports with integrated Device Level Ring (DLR) technology. This "R" (Redundant) designation ensures that the communication link remains active even if a single point of failure occurs in the Ethernet ring, making it an essential component for process automation and mission-critical industrial environments where downtime is not an option.
