Product Description
The 1734-AENT (Part Number: 612598290437) is a high-performance communication interface for the Allen-Bradley POINT I/O system. This EtherNet/IP adapter serves as a bridge for bi-directional data exchange between a remote POINT I/O assembly and a Logix-based master controller over an EtherNet/IP network. Designed for high-speed industrial environments, it manages real-time discrete and analog I/O data transmission while providing diagnostic feedback for the entire backplane.

The module features an integrated RJ45 port that supports 10/100 Mbps communication. With auto-negotiation and auto-sensing capabilities, it simplifies network setup by automatically detecting the optimal duplex mode and transmission speed. It uses standard Category 5 (CAT5) cabling, supporting both shielded and unshielded configurations in star or tree topologies.

Technical Specifications

Specification Details
Series POINT I/O 1734
Module Type EtherNet/IP Adapter
Catalog Number 1734-AENT
Field Power Distributor Current 10 A (maximum)
Power Protection Integrated Reverse Polarity Protection
LED Indicators Module Status (Red/Green), Network Status (Red/Green), POINTBus Status (Red/Green)
Operating Temperature -20 to 55 °C (-4 to 131 °F)

Diagnostic Capabilities and Integration

The 1734-AENT provides real-time feedback via front-facing LED indicators. The Module Status LED monitors internal health, the Network Status LED tracks the EtherNet/IP connection state, and the POINTBus Status LED checks the health of the local backplane. It is fully compatible with Studio 5000 Logix Designer, enabling easy integration with Add-On Profiles (AOPs) and simplifying configuration of remote I/O drops without the need for complex messaging logic.

Frequently Asked Questions

Q: Does the 1734-AENT support Ring Topologies?
A: No, the 1734-AENT supports only star or tree network topologies. For Device Level Ring (DLR) support, the 1734-AENTR (dual-port) is the recommended alternative.

Q: How many POINT I/O modules can a single 1734-AENT support?
A: The adapter can address up to 63 modules, though the actual limit depends on the total POINTBus current draw (1000 mA) and the controller’s RPI settings.
