Overview
Controller Features
The 1769-L30ER-NSE combines controller processing with Ethernet connectivity. Its dual Ethernet ports support network communication and DLR configurations, which provide a ring topology for connected devices. Meanwhile, the 1 MB memory capacity provides storage for controller programs and application data.
The controller also supports an SD card for data storage. The supplied configuration is described as including a 1 GB SD card, with support for cards up to 2 GB. Since this model has no RTC supercapacitor, the clock backup arrangement should be considered when planning controller operation and maintenance.
Ethernet Communication and Network Configuration
The controller provides two embedded copper Ethernet ports for EtherNet/IP communication. It supports up to 16 EtherNet/IP nodes and offers Device Level Ring (DLR) capability for network ring configurations. In addition, the embedded USB port supports programming access and firmware downloads.
Local I/O Expansion
The 1769-L30ER-NSE supports up to 8 local CompactLogix I/O expansion modules. This allows users to extend local signal capacity by adding compatible I/O modules to the controller configuration. It also supports distributed I/O communication over EtherNet/IP.
