1756-EN2TP | Allen-Bradley ControlLogix EtherNet/IP Communication Module

Product Overview

The Allen-Bradley 1756-EN2TP functions as a high-performance communication interface for ControlLogix systems, specifically designed to support Parallel Redundancy Protocol (PRP). This module facilitates seamless EtherNet/IP connectivity, enabling controllers to bridge data across the plant floor without a single point of failure. We offer this unit as 100% Brand New and Original, ensuring your critical infrastructure benefits from the latest hardware revisions and full factory performance standards.

Technical Specifications

Engineering Advantages

• Redundant Network Resilience: The 1756-EN2TP implements Parallel Redundancy Protocol (PRP). Unlike standard modules, it sends duplicate packets over two independent local area networks. If one path fails, the receiving node accepts the first arriving packet, ensuring zero-recovery-time switching and uninterrupted process control.

• High-Density Connectivity: With support for 256 CIP connections and 128 TCP connections, this module handles massive I/O traffic and peer-to-peer messaging simultaneously. It eliminates bottlenecks in large-scale architectures where high-speed data throughput is non-negotiable.

• Superior Interference Immunity: Industrial environments generate significant electrical noise. The 1756-EN2TP features robust ESD immunity (6 kV contact) and radiated RF immunity up to 10V/m. These protections prevent data corruption and unexpected module resets near high-frequency drives or heavy machinery.

• Thermal Efficiency: Despite its high processing power, the module dissipates only 5.1 W of power. This low thermal footprint prevents heat buildup within the ControlLogix chassis, extending the lifespan of adjacent I/O and processor modules.

FAQs

• How does the 1756-EN2TP differ from the standard 1756-EN2T?

  The "P" suffix denotes support for Parallel Redundancy Protocol (PRP). While the standard EN2T supports single or DLR (Device Level Ring) topologies, the 1756-EN2TP allows for fully redundant star topologies where two separate networks run in parallel for maximum uptime.

• Is this module compatible with existing 1756 ControlLogix chassis?

  Yes, it fits into any standard 1756 ControlLogix I/O slot. It requires no external power supply as it draws 1A directly from the 5.1V DC backplane.

• Can I configure the module via the USB port?

  Certainly. The integrated USB port provides a direct connection for firmware updates and initial IP address configuration via RSLinx, bypassing the need for an existing network connection during commissioning.

• Does the unit ship in original Allen-Bradley packaging?

  We guarantee this product is 100% Brand New. It ships in the original factory-sealed box with all original labels, ensuring authenticity and reliability for your automation project.
