1.Product Overview
The Allen-Bradley 1756-EN2TPXT/B EtherNet/IP™ Communication Module delivers enterprise-class networking for Rockwell Automation’s ControlLogix® systems, featuring dual 10/100/1000 Mbps ports with CIP Security™ and IEEE 1588 PTP v2 precision time synchronization. Designed for critical infrastructure, it supports seamless integration of I/O, drives, and HMIs across IT/OT networks. The module’s ruggedized design (-40°C to +70°C operation) includes conformal-coated PCBs and zinc-alloy housing for vibration/shock resistance (15g/5–2000Hz). Advanced diagnostics include per-port traffic mirrors for cyber-threat detection and encrypted firmware validation meeting IEC 62443-4-2 standards.
