A Dedicated Web Interface for ControlLogix Systems
The 1756-EWEB is an EtherNet/IP network server module specifically designed for the Allen-Bradley ControlLogix platform. It enables access to controller data via web pages, allowing users to monitor system status using standard web browsers without installing dedicated client software.
This module is commonly used in industrial environments to fulfill requirements for remote visualization, fault diagnosis, and basic monitoring while maintaining the existing control architecture.
