The Allen Bradley 1783-ETAP is an industrial EtherNet/IP tap module designed to integrate single-port Ethernet devices into industrial network architectures. It enables seamless communication within Device Level Ring (DLR) and linear topologies by providing a three-port embedded switch interface.
This module is widely used in Rockwell Automation architectures to simplify network expansion, improve connectivity flexibility, and maintain reliable EtherNet/IP communication in distributed automation systems.

System Role Overview
The 1783-ETAP acts as a network interface bridge for EtherNet/IP devices, particularly in architectures where:
- A single Ethernet device must join a DLR ring
- Linear and ring topologies need flexible device insertion
- Industrial communication redundancy is required
- Machine-level networks require embedded switching capability
Unlike a standard switch, the ETAP is designed specifically for control-system-aware networking, ensuring deterministic EtherNet/IP communication.
Key functions include:
- Enabling single-port devices to join DLR networks
- Providing embedded 3-port switching capability
- Supporting linear and ring Ethernet topologies
- Maintaining EtherNet/IP communication integrity
- Simplifying industrial network architecture
