Allen Bradley 1783-ETAP EtherNet/IP Tap Module

PLC Autocontroller – 20-year spare-part express

Allen-Bradley1783-ETAP  EtherNet/IP Tap Module

Product Overview

The Allen-Bradley 1783-ETAP, an EtherNet/IP Tap Module from Rockwell Automation, is designed specifically for Device Level Ring (DLR) network architectures. This module enables terminal devices lacking DLR functionality to connect to an EtherNet/IP ring network, achieving redundant communication in industrial networks and improving system reliability and network availability.

The 1783-ETAP features three 10/100 Mbps Ethernet ports: two for DLR ring network connections and one for connecting terminal devices such as PLCs, HMIs, frequency converters, industrial computers, or remote I/O modules. By integrating DLR technology, this module can quickly restore communication in the event of network outages or equipment failures, minimizing downtime risks.

With its compact design, easy installation, and excellent network redundancy, the 1783-ETAP is widely used in manufacturing, automotive, power systems, food and beverage, water treatment, and process automation industries.

Key Advantages

Supports DLR Ring Network Redundancy

The 1783-ETAP employs Device Level Ring technology, enabling millisecond-level network fault recovery. When a node or communication link in the ring network fails, the system automatically switches communication paths to ensure continuous transmission of critical control data.

Improved Network Reliability

By constructing a redundant industrial network architecture, communication interruptions caused by single points of failure are effectively avoided, improving the operational stability of automation systems.

Simplified Device Access

The module allows standard EtherNet/IP devices to quickly access the DLR network without the need for additional complex switches, significantly reducing network construction costs and implementation complexity.

Plug-and-Play Design

Supports Auto-Negotiation and Auto MDI/MDIX, simplifying installation and commissioning, and enabling rapid deployment into existing control systems.

Compact Industrial Design

Utilizing a DIN rail mounting structure, it occupies minimal control cabinet space, making it suitable for automation equipment and production line applications.

Industrial-Grade Environmental Adaptability

It possesses excellent vibration, shock, and electromagnetic interference resistance, enabling long-term operation in complex industrial environments.
