Allen-Bradley 1756-EN2T EtherNet/IP Bridge Module

The Allen-Bradley 1756‑EN2T EtherNet/IP Bridge Module is a single-port EtherNet/IP bridge for ControlLogix racks that links the PLC backplane to industrial Ethernet networks. It provides EtherNet/IP communication and bridging between the 1756 ControlLogix chassis and external Ethernet networks, enabling I/O messaging and CIP communications with hosts, HMIs, remote I/O, drives, and supervisory systems over Ethernet. Mounted in a 1756 ControlLogix chassis slot, this module is powered directly from the backplane and offers an RJ‑45 port supporting 10/100/1000 Mbps Ethernet. Indicators include link, activity, and status LEDs to monitor connectivity, and its supported protocols are EtherNet/IP, TCP/IP, and UDP/IP with explicit messaging and CIP communications over the bridge to the PLC backplane. It is designed for industrial Ethernet networking in automation and is commonly used in factory and process environments such as manufacturing plants, material handling, packaging machinery, assembly lines, and process facilities where reliable control networking is required. Common replacements include Allen Bradley 1756‑EN2TR, Allen Bradley 1756‑EN4TR, and Allen Bradley 1783‑ETAP.
