Overview
The Allen-Bradley 1761-NET-ENI Series A is a Ethernet interface module designed to extend networking capabilities of controllers without built-in Ethernet ports. The 1761-NET-ENI is part of the Allen-Bradley MicroLogix communication accessory family, developed to extend networking capabilities of controllers that do not have built-in Ethernet ports. It translates DF1 protocol to EtherNet/IP, enabling devices such as MicroLogix 1000, 1200, 1500, and SLC controllers to communicate on Ethernet networks. Compact and DIN rail–mounted, the 1761-NET-ENI provides a cost-effective solution for connecting legacy Allen-Bradley controllers to Ethernet infrastructures.
Key Features
- One 100 Base-T (RJ45) Port: 10/100MHz; One RS-232C Port: 2400, 4800, 9600, 19.2K, 38.4K baud
- The module supports up to six simultaneous connections, allowing integration with HMIs, SCADA systems, and programming software like RSLogix 500.
- Includes an RJ45 Ethernet port, RS-232 port, and built-in web server for basic configuration.
- UL, C-UL, CE, and Class 1, Division 2 certifications; this module provides Ethernet/IP connectivity to all DF1 full-duplex devices including all MicroLogix and CompactLogix controllers.
- Acts as a bridge between serial devices and Ethernet systems, enabling remote communication, diagnostics, and programming. This helps modernize legacy systems without replacing the entire controller or adding new Ethernet modules.
