Configured for enhanced web server communication in CompactLogix network platforms, the Allen-Bradley 1768-EWEB (1768-EWEB/A Communication Module) provides direct physical/electrical execution.

Model Identification Matrix

The 1768-EWEB functions as an interface bridge for CompactLogix control systems, providing web-based data access and diagnostics. The designation 1768-EWEB/A indicates the hardware revision level, which dictates compatibility with specific firmware versions and backplane bus communication velocity settings.

Hardware Specifications

Network Communication and Firmware Integration

The 1768-EWEB facilitates EtherNet/IP deterministic networks, enabling the integration of web-based diagnostics into the standard control architecture. Firmware flash compatibility is managed via the controller backplane, ensuring that the module maintains synchronization with the host processor's I/O scanning cycles. The module's data throughput is optimized for 100 Mbps full-duplex operation, supporting consistent packet delivery for network-based monitoring tasks without overloading the primary controller's scan time.

Field Installation Guidelines

Installation requires mounting the 1768-EWEB within an established 1768-series CompactLogix chassis. Before insertion, verify that the chassis power is removed. Align the module with the backplane connector and secure it using the provided retention screws to ensure chassis ground continuity. Shielded Category 5 or higher Ethernet cabling is required for proper data transmission and interference mitigation. Maintain physical separation from high-voltage AC cabling to prevent inductive coupling and signal corruption.

Delivery Information

Delivery time: 2-7 days when payment finish. Dispatch is managed via DHL, FEDEX, or UPS. Each module is secured using anti-static industrial packaging to ensure electronic integrity and prevent damage during transit.

Frequently Asked Questions

Q: Can the 1768-EWEB be removed or inserted while the chassis is powered?

A: The module supports Removal and Insertion Under Power (RIUP) when installed in a 1768 CompactLogix chassis, provided that electrical safety precautions are followed.

Q: What is the maximum number of concurrent clients supported?

A: The module supports a maximum of 32 concurrent clients for web-based data monitoring.

Q: How is the module isolated from the backplane?

A: The hardware provides 1500 V AC isolation to protect the backplane and the integrated controller circuitry from potential surges or electrical faults on the Ethernet network.

Q: Is external power required for the module?

A: No. The module draws power directly from the CompactLogix backplane at 5 VDC.
