Description
The Allen-Bradley 1756-EN2TRXT is a ruggedized EtherNet/IP communication bridge module designed for the ControlLogix-XT platform. Engineered for deployment in extreme industrial settings, this module provides reliable connectivity in environments challenged by high humidity, extreme temperatures, caustic airborne contaminants, and fungal growth. It integrates dual-port embedded switch technology, enabling efficient network communication and supporting advanced topologies such as Device Level Ring (DLR) to ensure high availability and minimal downtime in critical control applications.
Features
- Ruggedized Design: Built to withstand harsh conditions, including salt spray and extreme temperature fluctuations.
- Dual-Port Connectivity: Features two RJ45 ports for flexible linear or ring network configurations without the need for external switches.
- DLR Support: Embedded switch technology facilitates rapid recovery in the event of a media segment failure.
- High-Performance Messaging: Supports up to 256 CIP connections and 128 TCP/IP connections for robust data throughput.
- USB Interface: Includes a 1.1 USB port for simplified local diagnostics and initial configuration.
- Motion Synchronization: Capable of managing up to 8 synchronized motion axes via CIP Sync.

Installation Guidelines
- Ensure the ControlLogix chassis is properly grounded before installing the module.
- Handle the module using ESD-safe practices to prevent damage to sensitive internal components.
- Insert the module into any available slot in the chassis; ensure the backplane connector is fully seated and the module is secured with the top and bottom latching tabs.
- Use shielded twisted-pair cabling for Ethernet connections to minimize EMI in high-noise industrial areas.
- Always power down the chassis before inserting or removing communication modules to prevent electrical arcing or data corruption.
FAQ
Q: Does the 1756-EN2TRXT require an external switch for DLR topologies?
A: No. The module features an embedded switch, which allows it to participate directly in a Device Level Ring (DLR) without requiring an external industrial switch.
Q: Can this module be used in standard ControlLogix chassis?
A: Yes, the 1756-EN2TRXT is compatible with standard ControlLogix chassis, though it is specifically rated for the extended environmental requirements of the XT system.
