The Allen-Bradley 1769-AENTR is a dual-port EtherNet/IP adapter that enables 1769 Compact I/O™ to function asdistributed I/O. It allows users to reuse existing 1769 modules with next-generation CompactLogix™ controllers, protecting hardware investments while supporting flexible network topologies like Device Level Ring (DLR) and linear architectures.

Key Features
Device Level Ring (DLR) Support:Integrated switch functionality allows for redundant ring topologies, ensuring that a single cable break does not result in a loss of I/O communication.
Investment Protection:Specifically designed for migration strategies, allowing 1769 I/O to be controlled by newer controllers (like the 5069 series) over a standard Ethernet network.
Scalable Architecture:Enables the placement of I/O banks closer to field devices, significantly reducing the cost and complexity of long-distance point-to-point wiring.
Standardized Networking:Integrates seamlessly into an enterprise-wide EtherNet/IP strategy, simplifying data access for IIoT and plant-level analytics.
High Connection Density:Capable of managing large I/O counts with high-speed updates via its 128 available CIP connections.
