Allen-Bradley 1756-ENBT EtherNet/IP Communication Module

The Allen-Bradley 1756-ENBT EtherNet/IP Communication Module is a ControlLogix network interface module that enables Ethernet-based communication between PLCs, I/O devices, and industrial automation networks. Built for EtherNet/IP, it supports real-time data exchange across distributed ControlLogix systems via a 10/100 Mbps RJ45 Ethernet port and a ControlLogix backplane interface, and it is designed as a chassis-mounted solution compatible with ControlLogix PLCs operating from 0°C to 60°C. Maintenance teams, OEM machine builders, and system integrators rely on this module for network expansion, automation upgrades, system integration, and replacement of existing PLC communication interfaces. Typical applications include manufacturing lines, packaging equipment, material handling systems, robotic work cells, and process control environments where reliable Ethernet connectivity between controllers, HMIs, drives, and remote I/O is essential. Common replacements and cross-references include Allen-Bradley 1756-EN2T and 1756-EN2TR, with Siemens 6GK7343-1EX30-0XE0 listed as a cross-reference.
