Industry Applications
Machine Building and Equipment Manufacturing
This module helps machine builders achieve consistent performance by simplifying I/O architecture. With support for up to 128 EtherNet/IP connections and 96 TCP/IP connections, it enables scalable control without requiring multiple platforms.
System Migration and Upgrade
For users upgrading to newer CompactLogix controllers, the 1769-AENTR allows reuse of existing 1769 I/O systems, protecting prior investments. This reduces spare parts inventory and lowers migration costs.
Enterprise Connectivity
Using a single EtherNet/IP network, the module facilitates communication with HMI devices, SCADA systems, and other controllers. It supports linear and DLR topologies for flexible network design.

Installation and Setup Guidance
Mount the 1769-AENTR on a DIN rail using the integrated clip. It occupies one slot in the CompactLogix chassis. Configure the hardware IP address using the rotary switches on the module. Use RJ45 connectors per IEC 60603-7 and Category 5e minimum cable per TIA 568-B.1 for Ethernet connections. Ensure the backplane current draw of 500 mA at 5V DC is within the power supply capacity.
Maintenance and Reliability
Periodically inspect the module for dust accumulation and ensure adequate ventilation around the DIN rail enclosure. Verify that Ethernet cables are securely connected and free from damage. The module carries certifications including c-UL-us, CE, RCM, Ex, KC, and EtherNet/IP, supporting reliable operation in diverse environments.
Streamlining Control Architecture with the 1769-AENTR
It allows connection to Ethernet networks via the built-in Two (2) Ethernet communication ports, functioning as an embedded switch and supporting Linear, Star and Device Level Ring (DLR) topologies. This module supports transmission speed of 10/100 Mbps and 128 logical communications.

Compatibility and Integration
The 1769-AENTR is fully compatible with the CompactLogix platform and Bulletin 1769 Compact I/O series. It communicates via EtherNet/IP and supports messaging functions with PanelView HMIs, SCADA systems, and other controllers. The dual Ethernet ports enable embedded switch functionality for linear, star, or DLR topologies.
Selection Guide and Purchasing Advice
When selecting the 1769-AENTR, verify that your application requires up to 128 logical connections and 96 TCP/IP connections. AutoDCSTech offers this module along with technical support to ensure a smooth integration.
Troubleshooting and Common Issues
If the module does not establish network communication, check the rotary switch IP address settings and ensure the Ethernet cable meets Category 5e specifications. Verify that the backplane current draw does not exceed the power supply rating. For persistent issues, consult the module's diagnostic LEDs and reference the user manual for error codes.
