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

Allen-Bradley 1734-AENT is an Ethernet communication adapter in Rockwell Automation's Point I/O series, used to connect Point I/O modules to industrial Ethernet networks and achieve distributed I/O control. The following is a detailed introduction:

Product Overview

As the core component of the Point I/O system, 1734-AENT provides an Ethernet interface and supports Ethernet/IP protocol, which can connect up to 63 I/O modules to PLC or PAC controllers. It adopts a modular design and supports hot swapping, which is suitable for industrial automation scenarios that require flexible configuration and distributed control.
