Allen-Bradley 1761-NET-ENI is a serial-to-Ethernet gateway that provides Ethernet connectivity to legacy SLC 500 and MicroLogix controllers by bridging the DF1 serial port to a network. It operates as a transparent Ethernet bridge for DF1 communications, enabling data exchange and remote MSG-style instructions between the processor and an Ethernet TCP/IP network. The module is powered from 24 V DC (20.4–26.4 V range) and draws about 100 mA, with a dielectric isolation rating of up to 710 V DC; it includes an Ethernet interface for network access and a serial DF1 link to the controller.
