The 1768-EWEB module from Allen‑Bradley brings web server capabilities directly to the CompactLogix control platform. Specifically, this module allows plant managers and engineers to remotely monitor and modify control system data through standard XML web pages. It connects to Ethernet/IP networks using 802.3 compliant shielded or unshielded twisted pair cabling. Furthermore, the 1768-EWEB supports both internet and intranet connections, making it ideal for plant management applications and centralized data collection. This module transforms a standard CompactLogix controller into a web-accessible device without requiring additional hardware or complex programming.
The 1768-EWEB features one Ethernet RJ45 port with a Category 5 interface. It supports communication speeds of 10/100 Mbps with auto-negotiation capability. This module handles up to 64 TCP/IP connections and 128 CIP connections simultaneously. For web content storage, the 1768-EWEB provides 2 MB of flash file system space to store custom web pages and data views. The module draws 4.34 Watts of power from the backplane and has an isolation voltage rating of 30 Volts. It weighs approximately 7.5 ounces and comes without an enclosure, allowing flexible integration into existing panel layouts.
The core strength of the 1768-EWEB lies in its ability to serve dynamic web pages containing real-time control data. Users can access system information through any standard web browser without installing specialized client software. This approach simplifies remote diagnostics and reduces the need for on-site operator intervention. Moreover, the 1768-EWEB supports XML data exchange, which enables seamless integration with enterprise-level systems and third-party applications. Plant managers can view production metrics, equipment status, and alarm conditions from any location with network access.
This module occupies a single slot within the 1768 CompactLogix chassis. Specifically, the 1768-EWEB can be placed into slot 3 or slot 4 of the CompactLogix 1768 bus. It supports both DIN rail mounting and panel mounting for flexible installation options. The unit uses an open-style enclosure type and carries a T4 temperature code. Its lightweight design at 7.5 ounces minimizes mechanical stress on the mounting hardware.
First, ensure the power supply to the CompactLogix chassis is completely disconnected before installing the 1768-EWEB. Next, select either DIN rail mounting or panel mounting based on your enclosure layout. For DIN rail installation, snap the module onto the rail until the locking clip engages with an audible click. For panel mounting, use appropriate screws and secure the module to the backplate. Then, insert the 1768-EWEB into slot 3 or slot 4 of the 1768 bus, ensuring proper alignment with the backplane connectors. After securing the module, connect an Ethernet cable to the RJ45 port on the front face. Finally, reapply power and verify that the status LEDs indicate normal operation. The status indicators provide immediate feedback on network link activity and module health.
