ProSoft Allen Bradley AN-X2-AB-DHRIO ControlLogix Communication Gateway Module

Product Overview

The AN-X2-AB-DHRIO acts as a high-speed communication gateway that bridges modern EtherNet/IP networks with legacy Allen Bradley Data Highway Plus (DH+) and Remote I/O (RIO) systems. This module enables newer ControlLogix and CompactLogix controllers to extract data from, or control, legacy PLC-5, SLC 500, PanelView HMIs, and legacy drive systems. It provides a non-disruptive, phased migration path for aging plant floor networks without requiring complete system rewiring or immediate hardware replacement. We guarantee this product arrives in 100% brand new, original factory condition.

Technical Specifications

Engineering Advantages

• Phased Legacy Migration Without Downtime: This gateway eliminates the high risk of "rip-and-replace" upgrades. It permits a step-by-step modernization strategy where engineers replace old processors with ControlLogix CPUs while keeping the existing, functional RIO field racks and DH+ infrastructure completely intact.

• Flexible Dual-Mount Design for Tight Spaces: The compact housing supports both standard DIN rail clipping inside busy control enclosures and standalone desktop placement. This flexibility allows field engineers to deploy the unit inside crowded terminal boxes right at the legacy machine tap points.

• Web-Based Diagnostics and Configuration: The built-in RJ45 port hosts an onboard web server. Controls personnel configure network parameters, set baud rates, map rack numbers, and view real-time diagnostics directly via a standard web browser, avoiding the need for specialized, costly programming software.

• High Legacy Device Density Support: A single gateway manages up to 32 RIO logical racks, up to 8 legacy PanelView terminals, or up to 4 EtherNet/IP drives simultaneously. This high processing capacity replaces multiple legacy blue-hose scanner modules, drastically reducing cabinet power consumption and heat load.

FAQs

• Can this module run both DH+ and Remote I/O (RIO) protocols at the exact same time?

  No. The AN-X2-AB-DHRIO contains a single physical legacy port. You must configure the module firmware to operate either as a DH+ bridge or as a Remote I/O scanner/adapter during the initial web-based setup.

• Does this item arrive with a factory warranty and original packaging?

  Yes. We supply this AN-X2-AB-DHRIO gateway as a 100% brand new, authentic factory unit inside its original manufacturer packaging with all default factory seals intact.

• How do I set the node address and network baud rates on this unit?

  The module discards legacy physical DIP switches. You access the configuration interface by typing the default IP address of the gateway into your web browser, which opens the configuration utility to select baud rates (57.6k, 115.2k, or 230.4k) and rack numbers.

• What external power source does the module require?

  The module runs on a standard 24V DC external power supply. The internal electronics regulate this down to 12V DC with a maximum current draw of 200 mA, yielding a very low 2.4-watt thermal footprint inside your enclosure.
