Allen-Bradley 1756-EWEB ControlLogix Web Server Module

The Allen-Bradley 1756-EWEB ControlLogix EtherNet/IP Enhanced Web Server Module adds browser-based access to information from a ControlLogix controller over an Ethernet network. Installed in a ControlLogix chassis, the module hosts a built-in web server that lets authorized users view PLC data and controller status from any standard web browser, enabling quick diagnostics and data sharing without a separate HMI or SCADA client. Key specifications include catalog numbers 1756-EWEB and 1756-EWEBK, firmware versions up to V5.001, and official EDS support for the ControlLogix family, ensuring smooth integration with engineering tools. It supports up to 64 TCP/IP connections, allowing multiple clients to query data concurrently. As part of the ControlLogix ecosystem, the 1756-EWEB leverages EtherNet/IP to expose data from the controller over the network, giving plant personnel a simple, browser-based window into tag values and system information.
