Product Overview

The Allen-Bradley 1756-EN2TR functions as a high-performance communication interface for ControlLogix chassis. This module bridges the gap between your controller and EtherNet/IP enabled devices, facilitating real-time data exchange for high-speed I/O and motion control. It features dual RJ45 ports that enable advanced network topologies without the need for additional switches. We guarantee this unit is 100% Brand New and Factory Sealed, ensuring peak performance and full security compliance for your industrial network.

Technical Specifications

Engineering Advantages

• Network Fault Tolerance: The 1756-EN2TR implements Device Level Ring (DLR) technology, which maintains system communication even if a single point of failure occurs in the network ring.

• High-Speed I/O Processing: This module handles up to 5,000 packets per second, providing the bandwidth required for high-density I/O and precise motion control synchronization (CIP Motion).

• Bridge & Routing Capability: It acts as a bridge to link information from the ControlLogix backplane to the plant-wide Ethernet infrastructure, allowing seamless data collection and remote programming.

• Rapid Deployment: The integrated USB port facilitates direct local configuration. Engineers can assign IP addresses and flash firmware quickly without pre-existing network access.

FAQs

Is this 1756-EN2TR unit brand new?

Yes, we provide this module as 100% Brand New and Original in factory-sealed packaging. It includes the standard manufacturer's quality assurance.

Can I use the two ports for two separate networks?

No. The dual ports function as an internal switch. They share a single IP address and primarily support DLR (Device Level Ring) or Daisy-chain (Linear) topologies within the same subnet.

Does this module support CIP Safety?

Yes. The 1756-EN2TR supports CIP Safety, enabling you to transport safety data between GuardLogix controllers and safety I/O devices over the Ethernet network.
