Product Introduction
The Allen Bradley 1761-NET-ENI EtherNet Interface Module is a compact communication adapter designed to provide EtherNet connectivity to MicroLogix controllers through a serial interface. Developed by Allen-Bradley, this module enables legacy serial-based controllers to communicate over standard TCP/IP networks without replacing the existing PLC hardware.
The 1761-NET-ENI converts DF1 serial protocol into EtherNet/IP-compatible messaging, allowing MicroLogix 1000, 1200, and 1500 controllers to exchange data with SCADA systems, HMIs, programming workstations, and peer controllers across an Ethernet network. It is particularly valuable in modernization projects where Ethernet infrastructure already exists but the control system still relies on serial communication.
Its compact structure, DIN rail mounting, and straightforward configuration make it suitable for small and medium-sized automation systems that require remote monitoring, data acquisition, or plant-wide connectivity.

FAQ
-
How does the 1761-NET-ENI convert serial DF1 communication to Ethernet?
The module encapsulates DF1 serial messages into TCP/IP packets, enabling communication between MicroLogix controllers and Ethernet-based devices. -
Does the module support EtherNet/IP implicit messaging?
The 1761-NET-ENI primarily supports explicit messaging over TCP/IP rather than high-speed implicit I/O connections. -
Can multiple Ethernet clients connect simultaneously?
Yes, multiple clients such as HMIs and programming software can establish connections, depending on configuration and network load. -
How is the IP address assigned?
IP configuration is typically performed using a serial configuration utility before deployment on the network. -
Is network isolation provided?
The module includes electrical isolation between the serial interface and Ethernet circuitry to enhance system protection. -
What happens if network communication is interrupted?
The serial communication with the controller remains unaffected, while Ethernet communication resumes automatically once the network is restored. -
Does the module support DHCP?
Depending on firmware revision, static IP addressing is most commonly used for industrial stability. -
Can it be used for peer-to-peer PLC communication?
Yes, it enables controller-to-controller messaging over Ethernet using supported protocols. -
Is configuration software required?
Yes, initial setup requires a serial configuration utility to define communication parameters and IP settings. -
What diagnostic indicators are available?
LED indicators provide real-time feedback on power status, serial activity, and Ethernet link status.
