Allen-Bradley 1734-AENTR POINT I/O Dual-Port EtherNet/IP Adapter

ALLEN-BRADLEY POINT I/O 1734

Allen-Bradley 1734-AENTR POINT I/O Dual-Port EtherNet/IP Adapter

The Allen-Bradley 1734-AENTR is a 24 V DC POINT I/O adapter that connects a 1734 I/O station to EtherNet/IP through two 10/100 Mbps RJ45 ports.

The 1734-AENTR serves as the communications adapter at the left side of an Allen-Bradley POINT I/O station, linking the POINTBus backplane to an EtherNet/IP network.

Lifecycle / compatibility note: Rockwell Automation lists catalog number 1734-AENTR as Active. Exact series, firmware revision, certification, packaging and manufacturing origin must be confirmed for the offered unit.

Product Overview

The 1734-AENTR provides the communications interface between an EtherNet/IP network and the POINTBus backplane used by 1734 POINT I/O modules. Its dual-port design supports network pass-through without a separate switch at every station.

System capacity depends on POINTBus current, module selection, controller connections and any required expansion power supplies. Network parameters can be assigned through the front address switches, BOOTP/DHCP tools or stored configuration, subject to the applicable Rockwell instructions.

Key Functions

• Connects an Allen-Bradley 1734 POINT I/O station to an EtherNet/IP network.
• Provides two RJ45 ports in an embedded-switch configuration.
• Supports 10/100 Mbps Ethernet communication in compatible network layouts.
• Exchanges I/O data between the EtherNet/IP network and the POINTBus backplane.
• Supplies POINTBus power within the documented current limit.
• Provides module, network, POINTBus, link, system-power and field-power status indicators.
• Supports network commissioning through address switches, BOOTP/DHCP or stored parameters.

Technical Specifications

Technical values are product-identification guidance. Confirm the exact series, revision, markings, documentation and application requirements before ordering or installation.

Compatibility and Replacement Guidance

POINT I/O platform: The 1734-AENTR is intended for Allen-Bradley 1734 POINT I/O and must be configured as the adapter at the beginning of the POINTBus assembly.

System configuration: Verify controller, communication module, Add-On Profile/EDS, adapter series, firmware, electronic keying, chassis size, topology and POINTBus current before replacement.

Commissioning: Preserve and verify the IP address, subnet mask, gateway and chassis size. Replacement adapters may require configuration before I/O connections can be established.

Model differences: Do not assume the single-port 1734-AENT is equivalent. It does not provide the same dual-port network arrangement. Review the current Rockwell compatibility records before substituting a different series or catalog number.

Frequently Asked Questions
