Allen-Bradley 1734-AENT POINT I/O EtherNet/IP Communication Adapter Module

Product Description

The Allen-Bradley 1734-AENT is a high-performance EtherNet/IP communication adapter for the POINT I/O platform, providing a reliable interface between distributed I/O modules and a centralized EtherNet/IP controller. Acting as the gateway for a POINT I/O assembly, it enables high-speed exchange of real-time I/O data and diagnostic information over standard Ethernet networks.

Designed for flexible, distributed control architectures, the 1734-AENT helps reduce wiring costs and improve system scalability. A single 10/100 Mbps RJ45 Ethernet port with auto-negotiation supports common star and tree topologies, while integrated status LEDs allow quick, localized diagnostics of module, network, and POINTBus operation.

Technical Specifications

Core Application Scenarios

• Distributed I/O Architectures
  Locating POINT I/O racks close to machines while maintaining high-speed connectivity to ControlLogix or CompactLogix controllers.

• Real-Time Process Monitoring
  Transferring digital and analog I/O data together with module diagnostics for enhanced visibility and predictive maintenance.

• System Expansion
  Adding new I/O nodes to an existing EtherNet/IP network without major control system redesign.

Technical FAQ

Q: How many POINT I/O modules can the 1734-AENT support?
A: Up to 63 POINT I/O modules, provided the total backplane current consumption does not exceed the 1.0 A POINTBus limit.

Q: Does the 1734-AENT support Device Level Ring (DLR)?
A: No. The standard 1734-AENT has a single Ethernet port and supports star or tree topologies only. For DLR, the 1734-AENTR (dual-port) adapter is required.

Q: Can the IP address be set manually?
A: Yes. The IP address can be configured using the on-board thumbwheel switches or via BOOTP/DHCP software tools.
