Allen-Bradley 1768-EWEB CompactLogix Enhanced Web Server Module

Configured for EtherNet/IP communication and embedded web service hosting in CompactLogix 1768 controller systems, the Allen-Bradley 1768-EWEB (1768-EWEB Enhanced Web Server Module) provides direct physical/electrical execution.

Hardware Specifications

EtherNet/IP and Ethernet Deterministic Networks

• EtherNet/IP Deterministic Networks: Handles up to 128 concurrent CIP connections and 64 TCP/IP socket connections over a 10/100 Mbps auto-negotiating RJ45 Ethernet link, transmitting control data and web diagnostics across industrial IP networks.
• I/O Density Scaling: Integrates web server data bridging and custom socket interfaces into a single 1768 slot without consuming secondary controller communications capacity.
• Firmware Flash Compatibility: Fully compatible with Studio 5000 / RSLogix 5000 environments, allowing firmware flashing, web page customization, and socket control execution via standard controller routines.

Frequently Asked Questions

Q: What maximum number of simultaneous CIP and TCP/IP connections does the 1768-EWEB module support?

A: The module supports up to 128 simultaneous CIP connections and 64 TCP/IP socket connections for concurrent HMI, web server, and controller communication.

Q: Does the 1768-EWEB module support custom web page hosting and open socket communications?

A: Yes, the module features built-in storage and processing capabilities to host user-defined XML/HTML web pages and execute open TCP/UDP socket messaging routines.

Q: What Ethernet transmission speeds are supported on the physical RJ45 port?

A: The single RJ45 port supports 10 Mbps and 100 Mbps fast Ethernet communication speeds with auto-negotiation.

Field Installation Guidelines

• Backplane Slot Mounting: Seat the module securely into any open slot on the 1768 system backplane to the left of the CPU, ensuring top and bottom chassis latches engage.
• Ethernet Cable Termination: Connect Category 5e or Category 6 shielded twisted-pair (STP) cables fitted with standard RJ45 connectors to the front network port.
• Noise Isolation: Maintain proper physical separation between the Ethernet network media and high-voltage AC lines or VFD power leads within the panel enclosure.
• System Grounding: Confirm the 1768 mounting chassis is bonded to the main cabinet ground bus using a short, low-impedance copper strap to satisfy EMC standards.
