Allen-Bradley 1761-ENT-ENI Ethernet Interface Module | MicroLogix 1000

Allen-Bradley 1761-ENT-ENI Ethernet Interface Module – MicroLogix 1000 Series

When a MicroLogix 1000 controller loses its Ethernet connectivity on the plant floor, the consequences cascade fast — SCADA systems go blind, remote diagnostics become impossible, and maintenance teams are forced into manual intervention that halts production. The Allen-Bradley 1761-ENT-ENI Ethernet Interface Module exists precisely to prevent this scenario, serving as the dedicated EtherNet/IP gateway that bridges your MicroLogix 1000 PLC to modern industrial networks with zero compromise on reliability.

Within the MicroLogix 1000 product family, the 1761-ENT-ENI occupies a critical niche: it is the purpose-built Ethernet interface designed specifically for the 1761 platform, enabling full EtherNet/IP protocol support where native Ethernet was not available. Globally, Allen-Bradley MicroLogix controllers remain one of the most widely deployed small PLC platforms across discrete manufacturing, building automation, and OEM machinery — and the 1761-ENT-ENI is the key that unlocks their integration into contemporary IP-based control architectures.
