The Allen-Bradley 1783-ETAP2F is a 3-port EtherNet/IP tap featuring two fiber-optic ports and one copper port. It enables DLR ring redundancy and long-distance fiber connectivity for robust industrial automation networks.
The Allen-Bradley 1783-ETAP2F functions as a high-performance connectivity solution designed to integrate non-DLR (Device Level Ring) equipment into a redundant EtherNet/IP ring topology. This module provides a single copper port for local device connection and two 100 Base-FX fiber-optic ports for ring infrastructure. By utilizing fiber-optic media, the tap facilitates high-speed data transmission over significantly longer distances while providing total immunity to electromagnetic interference (EMI).
Network resilience serves as the core objective of the 1783-ETAP2F. It supports the Device Level Ring protocol, which allows the network to recover nearly instantaneously from a single point of failure. If a cable break occurs, the tap automatically reroutes traffic, ensuring that communication between controllers and I/O remains uninterrupted. Furthermore, the hardware utilizes a 24V DC power input and features a compact, DIN-rail mountable design that saves valuable space within industrial control panels.
The module simplifies network diagnostics through its comprehensive array of front-panel LED indicators. These lights provide real-time status updates on link activity, ring integrity, and power health. Because it operates as a “plug-and-play” device within the Logix5000 environment, engineers can configure and monitor the tap through standard Rockwell Automation software tools. Consequently, this module represents a critical component for manufacturers who require the high-speed isolation and long-range capabilities of fiber optics without sacrificing the reliability of a ring network.
