Allen-Bradley 1768-EWEB CompactLogix Enhanced Web Server Module
The 1768-EWEB is a CompactLogix enhanced web server module designed by Allen-Bradley to provide customized web page hosting, remote diagnostics, and network bridge routing. It equips 1768-based CompactLogix controllers with an isolated Ethernet communication path, enabling operators and engineers to access real-time system data, custom diagnostics, and graphical web displays through a standard web browser without dedicated HMI hardware.
Network Capabilities and High Connection Density
The 1768-EWEB module features a single 10/100 Mbps RJ45 Ethernet port supporting auto-negotiation for full-duplex communication. Engineered for data-intensive communication architectures, it manages up to 64 TCP/IP connections and 128 simultaneous CIP (Common Industrial Protocol) connections. This capacity ensures stable bridging, data logging, and concurrent user browser sessions across plant networks.
Integrated socket interface capabilities allow the module to exchange raw TCP/UDP data frames with non-CIP devices, including barcode readers, web interfaces, and third-party IT infrastructure.
Onboard Storage and Custom Web Server Functions
Equipped with 2 MB of non-volatile flash memory, the module hosts user-developed HTML web pages, XML data views, and system configuration templates. Plant personnel can monitor tag values, view diagnostic logs, and set controller clock parameters directly through network browsers.
The web server capabilities eliminate the need for specialized client software when performing remote system checks, making it ideal for distributed machinery and remote automated installations.
System Compatibility and Installation Requirements
The module operates specifically on the 1768 local expansion bus alongside CompactLogix controllers such as the 1768-L43 and 1768-L45. It installs directly into slots 3 or 4 of the 1768 chassis bank.
The unit draws 834 mA at 5.2 VDC backplane power, resulting in a total power consumption of 4.34 W. Standard RJ45 Category 5e copper cabling connects the module to industrial Ethernet switches or network nodes.

Installation Guidelines
Before installing the module into the chassis:
- Turn off main power to the CompactLogix controller chassis and connected I/O banks.
- Align the module's circuit board connectors with slot 3 or slot 4 on the 1768 controller backplane bus.
- Firmly slide the module until the top and bottom locking levers click securely into place.
- Secure the module to the panel or DIN rail using M4 or #8 mounting screws tightened to 1.16 Nm (10 in-lb) of torque.
- Connect an Ethernet cable compliant with ISO/IEC 24702 or TIA 568-B.1 (Category 5e or higher) into the front RJ45 port.
Frequently Asked Questions
Q: What controllers are compatible with the 1768-EWEB web server module? A: The 1768-EWEB is designed specifically for CompactLogix 1768 backplane systems and is compatible with 1768-L43 and 1768-L45 controllers. It cannot be used in 1769-only CompactLogix chassis.
