1768-ENBT CompactLogix EtherNet/IP Communication Bridge Module | Allen-Bradley

Product Overview

The Allen-Bradley 1768-ENBT functions as the primary high-speed communication gateway for the CompactLogix 1768 controller platform. This bridge module enables the controller to connect with plant-wide networks, remote I/O, and HMI systems via the EtherNet/IP protocol. We supply this unit as 100% Brand New and Original, ensuring your industrial network maintains peak deterministic data throughput and secure connectivity across your automation architecture.

Technical Specifications

Engineering Advantages

• High-Speed Deterministic Networking: The 1768-ENBT manages EtherNet/IP traffic at 100 Mbps, providing the necessary bandwidth for real-time I/O control and high-speed interlocking. This module stabilizes data packet delivery, ensuring that motion control and safety signals arrive without the jitter associated with unmanaged network traffic.

• Seamless Plant-Wide Integration: This module bridges the gap between the factory floor and enterprise-level networks. It allows the CompactLogix CPU to share critical production data with SCADA systems, SQL databases, and MES platforms through standard Ethernet infrastructure.

• Simplified System Configuration: The 1768-ENBT supports rapid integration within the RSLogix 5000 / Studio 5000 environment. Engineers configure the module through standard Add-On Profiles (AOP), which eliminates the need for manual bit-mapping and reduces overall commissioning time.

• Robust Hardware Reliability: Designed for harsh industrial environments, the module operates efficiently at temperatures up to 60°C. The hardware resists electromagnetic interference (EMI), protecting the signal integrity of the RJ45 port even when installed in cabinets near high-frequency variable speed drives.

• Versatile Mounting Logic: The module snaps directly onto the 1768 bus, which supports both DIN rail and panel mounting. This flexibility allows for high-density hardware placement in cramped control cabinets, saving valuable panel space while maintaining easy access to the Category 5 cable connection.

FAQs

• Does the 1768-ENBT support motion control?

  The 1768-ENBT facilitates EtherNet/IP communications for I/O and messaging. For integrated motion on EtherNet/IP (CIP Motion), ensure your controller and firmware version support motion tasks via this specific bridge module.

• Can I use standard Category 5e cables with this module?

  Yes. The 1768-ENBT utilizes a standard RJ45 interface and supports Category 5 or higher cabling. For industrial environments, we recommend using shielded Category 5e or Category 6 cables to prevent electrical noise from disrupting network communications.

• How do I assign the initial IP address to a Brand New 1768-ENBT?

  Use the Rockwell Automation BootP/DHCP utility to assign an initial IP address based on the module’s MAC address. Once established, you can set a static IP address through the RSLinx software or the Studio 5000 module configuration tab.

• What is the difference between the 1768-ENBT and 1769-ENBT?

  The 1768-ENBT specifically fits the 1768 controller's high-speed expansion bus (usually located to the left of the CPU), whereas the 1769-ENBT fits the standard 1769 I/O bus. They are not physically interchangeable due to the different backplane connector designs.
