1756-ENET Allen-Bradley Ethernet Communications Interface

Overview

The Allen-Bradley 1756-ENET is an Ethernet communication module designed for the ControlLogix platform. This module offers robust connectivity for real-time data exchange, optimized messaging, and integration with the Common Industrial Protocol (CIP). With both Ethernet and AUI ports, the 1756-ENET provides flexible communication options for industrial networks. Although discontinued, it remains a valuable asset for users seeking reliable industrial Ethernet connectivity for ControlLogix systems. Replaced by the 1756-ENBT model, it supports applications requiring synchronized data transfer and real-time control.
