Core Functionality and System Compatibility
The 1768-ENBT acts as the primary communication interface for your CompactLogix system. This module enables a 1768-L43 or 1768-L45 controller to talk to Ethernet/IP devices. You can connect drives, motor starters, and smart controllers directly to this network. It supports up to 64 CIP connections and 32 TCP/IP connections for robust data exchange. This makes it ideal for complex automation architectures.
Technical Specifications for Engineers and Buyers
This module operates at a speed of 10/100 Mbps with auto-negotiation. It uses standard Category 5 or Category 6 cables with RJ45 connectors. The module requires a backplane current of 834 mA at 5.2V DC. Its total power consumption is only 4.34 Watts. You can mount it on a DIN rail or directly onto a panel within your 1768 CompactLogix assembly.
Scalability for Different Controller Platforms
The number of supported 1768-ENBT modules depends on your controller. A 1768-L43 processor supports up to two instances of this module. A more powerful 1768-L45 processor supports up to four instances. This scalability allows you to expand your network as your production needs grow. It provides a clear upgrade path without changing your core automation platform.
Environmental Durability and Physical Installation
This communication module withstands harsh industrial environments. It operates reliably in temperatures from 0° to +60°C (+32° to +140°F). The unit handles operating vibration of 5 g and operating shock of 30 g. You must follow proper electrostatic discharge precautions during installation. Always touch a grounded object or wear a static-free wristband before handling the module.
Network Topology and Connectivity Options
The 1768-ENBT supports a linear network topology for simple wiring. It works with commercial Ethernet switches or industrial Stratix switches. This module communicates with legacy Allen-Bradley 1336 drives and PowerFlex drives. It also connects to Kinetix servo drives, ControlLogix platforms, and many third-party devices. This broad compatibility simplifies your vendor management.
Status Indicators and Operational Safety
The module includes three critical status indicators for easy troubleshooting. You will find a link status indicator, an OK status indicator, and a network status indicator. Always wait for these lights to turn off before powering down the system. This practice saves any project data still writing to the module’s memory. It prevents data corruption and ensures system integrity.
