Product Overview
The Allen‑Bradley 1756‑EN2T is an EtherNet/IP bridge module for ControlLogix chassis. It acts as interface between ControlLogix backplane and EtherNet/IP industrial network, handling implicit real‑time I/O, explicit message, motion and safety data exchange. It enables the controller to communicate with remote EtherNet/IP I/O, drives, HMI and other Logix controllers. It supports CIP motion for multi‑axis motion application and CIP‑safety for safety‑related device communication. It resolves typical pain‑points: limited on‑board Ethernet performance of older CPU, insufficient network connection quantity, lack of motion‑capable Ethernet bridge. Automation engineers, panel builders and maintenance technicians benefit from hot‑swap capability, large connection capacity, motion‑ready performance and drop‑in spare replacement for existing ControlLogix systems。
