The Allen Bradley 1788-ENBT (part number 96350676) is a high-performance communication interface module designed by Rockwell Automation. It serves as a bridge between the EtherNet/IP network and various industrial platforms, enabling seamless data exchange, real-time control, and remote messaging for automated systems.

 

Product Overview

The 1788-ENBT Series A is engineered to provide high-speed, deterministic communication for industrial automation environments. It allows controllers to interface with I/O modules, drives, and other Ethernet-enabled devices. By utilizing standard Ethernet protocols (TCP/IP and UDP), this module simplifies network architecture while maintaining the robust timing required for discrete and process control applications.

Technical Datasheet & Parameters

 

Country of Origin

The Allen Bradley 1788-ENBT 96350676 is designed and manufactured in the USA.

 

Application Fields

• Distributed I/O Systems: Connecting remote Flex I/O or Point I/O racks to a central Logix controller.
• Drive Control: Synchronizing PowerFlex drives over an Ethernet backbone for precise speed and torque management.
• HMI Connectivity: Providing a high-bandwidth data link for PanelView terminals and SCADA workstations.
• Plant-Wide Networking: Integrating isolated machine cells into a centralized Manufacturing Execution System (MES).
• Remote Diagnostics: Enabling off-site engineering support to monitor PLC status and modify logic through secure VPN tunnels.

 

Technical Description

Technically, the 1788-ENBT utilizes an embedded web server that allows for module configuration and basic diagnostics via a standard web browser. It supports both half-duplex and full-duplex communication modes to optimize throughput. The module features specialized hardware for CIP (Common Industrial Protocol) encapsulation, ensuring that industrial control data is prioritized over standard network traffic. The “96350676” specification ensures compatibility with specific backplane architectures and firmware revisions required for high-availability synchronization.

 

Usage Instructions

1. Hardware Installation: Insert the 1788-ENBT module into the designated slot of the chassis. Ensure the module is firmly seated and the locking tabs are engaged.
2. Network Wiring: Connect a Category 5e or Category 6 shielded Ethernet cable to the RJ45 port. Avoid routing the cable near high-voltage motor leads to reduce noise interference.
3. IP Address Assignment: Use the BOOTP/DHCP utility or RSLinx software to assign a unique IP address to the module based on its MAC address (printed on the side label).
4. Software Configuration: Within the Studio 5000 or RSLogix 5000 I/O tree, add the 1788-ENBT module and define its slot position and requested packet interval (RPI).
5. Status Monitoring: Observe the front-panel LEDs. The “LINK” LED should be solid green for an active connection, and the “NET” LED indicates the status of CIP communications.
