Description
The Allen-Bradley 1769-L30ER belongs to the 5370 L3 CompactLogix series and provides a reliable control solution with 1 MB of user memory, dual Ethernet ports, and a USB interface.

Its embedded Ethernet ports support multi-node and point-to-point communication and can operate in linear, star, and Device Level Ring (DLR) topologies. With support for up to 16 Ethernet nodes, the 1769-L30ER enables seamless integration with devices such as HMIs, SCADA systems, databases, gateways, and other controllers.

The dual Ethernet ports act as an embedded switch, ensuring that the same network traffic is available across both ports, which enhances flexibility and resiliency in automation networks.
