Allen-Bradley 1756-ENBT EtherNet IP Bridge Module

The Allen-Bradley 1756-ENBT EtherNet/IP Bridge Module provides robust EtherNet/IP networking and CIP routing capabilities for ControlLogix systems, enabling real-time data exchange and bridging across PLCs, HMIs, remote I/O, and networked devices. Designed for installation in 1756 ControlLogix racks, it features dual RJ-45 Ethernet ports rated at 10/100/1000 Mbps and supports EtherNet/IP, TCP/IP, and UDP/IP, with redundant networking through its dual-port architecture and LEDs for Link, activity, and status to simplify diagnostics. Core functions include I/O messaging, explicit messaging, and CIP routing/bridging; it is powered by the backplane and mounts in a 1756 ControlLogix chassis, ensuring compatibility with the ControlLogix PLC family. Common applications span factory and process automation environments where EtherNet/IP communication and bridging are required, such as manufacturing plants, material handling, assembly lines, and process control installations that demand real-time control, diagnostics, and data exchange among PLCs, operator interfaces, and distributed I/O.
