Allen-Bradley 1734-AENTR Point I/O series redundant Ethernet communication adapter

Allen-Bradley 1734-AENTR is a redundant Ethernet communication adapter in Rockwell Automation's Point I/O series, used to achieve distributed I/O connection and data transmission in industrial automation systems. The following is a detailed introduction:

Product Overview

As the core component of the Point I/O series, 1734-AENTR provides redundant communication capabilities of dual Ethernet ports and supports multiple network protocols such as DeviceNet, ControlNet and Ethernet/IP. It allows up to 63 I/O modules to be connected to the industrial Ethernet network and ensures high availability of the system in the event of network failure through redundant design.

Technical Specifications

Network Features

Status Indicator

LED indicator: including system status, power supply, Ethernet A/B port status, communication status, etc.

Features

Dual Ethernet port redundancy

Redundant communication is achieved through two independent Ethernet ports. When one port fails, it automatically switches to the other port to ensure uninterrupted data transmission.

Flexible network topology

Supports linear topology and ring network structure to meet different industrial site layout requirements.

Plug and Play

Supports hot swapping, and modules can be replaced while the system is running to reduce downtime.

Integrated diagnostic function

Provides real-time network status monitoring and diagnostic information for quick troubleshooting.

Wide device compatibility

Can be seamlessly integrated with Rockwell Automation's PLC, HMI and other industrial equipment.

Typical application scenarios

Critical industrial systems: scenarios where network interruptions cannot be tolerated in industries such as automotive manufacturing, food processing, and power.

Distributed I/O system: In large factories or production lines, decentralized I/O modules are connected to the central control system.

Applications requiring high availability: such as process control, robot control, logistics automation, etc.

Matching Use

I/O Modules: Can be used with 1734 series digital, analog and special function I/O modules.

Software Tools: Configuration and programming through Studio 5000 Logix Designer or RSLogix 5000.

Network Equipment: Need to cooperate with industrial Ethernet switches, routers and other equipment to build a complete network.
