Product Description
Overview
The Allen-Bradley 1734-AENTR EtherNet/IP adapter is part of Rockwell Automation’s POINT I/O (Bulletin 1734) platform. It functions as the network interface between distributed POINT I/O modules and Logix-based controllers, with integrated Device Level Ring (DLR) capability for network redundancy.
Designed for high-availability control systems, 1734-AENTR supports scalable distributed I/O architectures while maintaining deterministic Ethernet communication.
Network Architecture and Redundancy
The 1734-AENTR features two 10/100 Mbps RJ45 Ethernet ports, enabling linear, star, and ring topologies. Unlike standard adapters, it includes built-in DLR ring supervision, allowing the module to actively manage ring redundancy and maintain communication during single-point network faults.
From field experience, this design significantly reduces downtime in packaging lines and continuous-process equipment where Ethernet reliability is critical.
