The 1756-EN2TXT is a premium EtherNet/IP communication module engineered by Allen-Bradley for the ControlLogix platform. This module delivers deterministic, high-speed data exchange between controllers, I/O devices, and enterprise systems, supporting up to 256 TCP/IP connections and 512 CIP connections. With dual RJ45 ports supporting Device Level Ring (DLR) technology, the 1756-EN2TXT ensures network redundancy and fault tolerance critical for process control and discrete manufacturing. It is fully compliant with ODVA’s EtherNet/IP specifications and offers seamless integration with Rockwell Automation’s Studio 5000 environment. The module is housed in a rugged metal enclosure, designed for extended temperature ranges and vibration resistance, making it ideal for harsh industrial environments.
