Allen-Bradley 1756-EWEB ControlLogix Enhanced Ethernet Web Server Module

Product Overview

The Allen-Bradley 1756-EWEB functions as a specialized Ethernet bridge and web server for the ControlLogix platform. It bridges the gap between the factory floor and IT infrastructure by providing customized web pages and remote data access via standard browsers. This module enables maintenance teams and engineers to monitor real-time controller data, view system diagnostics, and interact with the backplane from any networked PC. We supply this module as 100% Brand New and Factory Original, ensuring your network security and hardware integrity remain uncompromised.

Technical Specifications

The 1756-EWEB occupies a single slot and integrates seamlessly into any 1756 chassis environment.

Engineering Advantages

• Remote Diagnostic Capabilities: The 1756-EWEB eliminates the need for onsite programming software for basic troubleshooting. It serves diagnostic information directly to standard web browsers, allowing remote technicians to identify faults instantly.

• Custom Web Page Hosting: Engineers can develop and store custom HTML pages directly on the module. This enables the creation of lightweight HMI-style dashboards that operators can access without dedicated hardware, reducing overall system costs.

• Efficient Data Bridging: This module manages bridging for messaging (MSG instructions) between Ethernet/IP devices and other ControlLogix backplane modules. It offloads communication tasks from the main CPU, preserving processor bandwidth for critical logic execution.

• Versatile Chassis Placement: The hardware installs in any available slot of a 1756 ControlLogix chassis. This flexibility simplifies the expansion of existing systems where rack space is limited, requiring only a single slot to add comprehensive web connectivity.

FAQs

• Does the 1756-EWEB support the same number of connections as a 1756-ENBT?

  No. The 1756-EWEB prioritizes web services and data bridging rather than high-speed I/O control. While it handles messaging efficiently, you should use an ENBT, EN2T, or EN3T module for high-performance remote I/O or motion control.

• How do I access the module's configuration for the first time?

  You can assign an IP address via the BOOTP/DHCP utility or through RSLinx software. Once assigned, simply enter the IP address into a compatible web browser to access the internal configuration and status pages.

• What browser versions are compatible with this module?

  The module supports standard modern browsers. While legacy documentation mentions Internet Explorer 5.5 and 6, the 1756-EWEB utilizes standard HTTP protocols compatible with current professional web browsers.

• Is the 1756-EWEB a 100% Brand New original product?

  Yes. Every 1756-EWEB we ship is 100% Brand New and Original, arriving in factory packaging to ensure you receive the latest hardware revision and full operational lifespan.
