The Allen-Bradley 1715-AENTR is an EtherNet/IP Adapter Communication Module from the Rockwell Automation Bulletin 1715 Redundant I/O series. This adapter is designed to provide high-performance and fault-tolerant network connectivity for redundant I/O systems in critical industrial applications. A single pair of 1715-AENTR modules can support up to twenty-four (24) I/O modules, enabling scalable and resilient system configurations. The 1715-AENTR features autosensing 10/100BASE-TX Ethernet ports that support both Device Level Ring (DLR) and star network topologies, ensuring network flexibility and redundancy. Engineered for reliability and continuous operation, the 1715-AENTR adapter enhances communication integrity, simplifies integration with Logix-based controllers, and maintains uninterrupted data exchange in mission-critical automation environments.
