AN-X2-AB-DHRIO Product Description

The ProSoft AN-X2-AB-DHRIO is a high-performance EtherNet/IP to Data Highway Plus (DH+) and Remote I/O (RIO) communication gateway engineered for industrial facilities that demand seamless protocol bridging, reduced energy overhead, and uninterrupted production continuity. As factories transition toward energy-aware automation architectures, the AN-X2-AB-DHRIO serves as a critical integration node — connecting legacy Allen-Bradley DH+ and RIO networks to modern EtherNet/IP infrastructure without costly controller replacements or full-line shutdowns.

Designed for demanding environments including automotive assembly, food and beverage processing, chemical manufacturing, and discrete parts production, this gateway enables plant engineers to retain proven legacy control assets while layering on modern energy monitoring, predictive diagnostics, and real-time data visibility. The result is a measurable reduction in idle energy consumption, thermal load, and unplanned downtime — all without disrupting existing production rhythms.

In a modern energy-optimized production environment, the AN-X2-AB-DHRIO functions as the communication backbone that ties together multiple automation layers. When paired with a ControlLogix L7x series PLC acting as the EtherNet/IP scanner, the gateway transparently maps DH+ node data into the controller's tag database — enabling the PLC to make real-time load-shedding decisions based on live device status without polling delays that waste CPU cycles and inflate energy budgets.

On the drive side, PowerFlex 755 variable frequency drives (VFDs) connected via RIO adapters can have their speed references and energy feedback registers read directly through the AN-X2-AB-DHRIO, allowing the control system to dynamically adjust motor speeds in response to production demand — a key lever for reducing motor energy consumption by 20–40% during partial-load cycles. Similarly, Kinetix 5700 servo drives operating on the EtherNet/IP backbone benefit from synchronized motion coordination data flowing through the gateway, ensuring servo axes are not over-energized during idle or transition states.

For power quality visibility, integrating a PowerMonitor 5000 power metering module on the EtherNet/IP network alongside the AN-X2-AB-DHRIO creates a closed-loop energy feedback path: real-time kW, kVAR, and power factor data from the PowerMonitor informs the ControlLogix PLC, which can then issue corrective commands to drives and contactors via the DH+ or RIO segments. This architecture eliminates the need for separate energy management hardware and reduces the number of active network nodes drawing standby power.

On the I/O layer, 1756-IB16 and 1756-OB16 digital I/O modules in the ControlLogix chassis receive device-ready and fault signals from legacy RIO-connected equipment through the gateway, enabling the PLC to de-energize non-critical loads during scheduled production pauses. PanelView Plus 7 HMI terminals connected to the EtherNet/IP network display consolidated energy dashboards — pulling DH+ node status through the AN-X2-AB-DHRIO — giving operators a single-pane view of drive states, motor currents, and alarm conditions without requiring separate legacy programming terminals.

For facilities running FactoryTalk View SE SCADA platforms, the AN-X2-AB-DHRIO exposes all DH+ and RIO device data as standard EtherNet/IP tags, making legacy node information available to SCADA historians and energy analytics engines without custom OPC bridges. 1783-ETAP EtherNet/IP tap modules can be deployed inline to provide passive network monitoring without disrupting live traffic, supporting non-intrusive energy audits. Where wireless sensor integration is required, 1752-L24BBB SmartGuard safety controllers and POINT I/O 1734-AENT EtherNet/IP adapters can be added to the same network segment, consolidating safety and process I/O into the unified energy management architecture enabled by the AN-X2-AB-DHRIO gateway.

Legacy DH+ and RIO networks were designed for reliability, not energy transparency. Without a modern gateway like the AN-X2-AB-DHRIO, plant engineers have no direct path to expose legacy device energy states to higher-level energy management systems (EMS) or SCADA platforms. This creates invisible energy waste: motors run at full speed during low-demand periods, drives remain energized during shift changes, and fault conditions go undetected until they cause unplanned downtime — all of which inflate energy costs and reduce equipment lifespan.

By bridging DH+ and RIO segments into the EtherNet/IP domain, the AN-X2-AB-DHRIO enables the control system to implement demand-based load management: non-critical conveyors, pumps, and blowers connected via RIO adapters can be staged on and off in response to real-time production throughput signals, reducing peak demand charges and lowering the facility's overall thermal load. Reduced thermal load directly translates to lower HVAC energy consumption in control rooms and panel enclosures — a secondary energy saving that is often overlooked in traditional automation audits.

From a production rhythm perspective, the gateway's low-latency data exchange ensures that PLC scan cycles are not extended by slow legacy network polling. Consistent, predictable scan times mean that motion sequences, conveyor indexing, and robotic cell handshakes execute on schedule — eliminating the micro-stoppages and re-synchronization delays that fragment production flow and force equipment to run longer than necessary to meet output targets.

For predictive maintenance programs, the AN-X2-AB-DHRIO makes legacy device diagnostic registers — drive fault codes, RIO adapter status words, and DH+ node health indicators — available to cloud-connected analytics platforms via the EtherNet/IP backbone. Early detection of drive overtemperature conditions, communication retries, or adapter faults allows maintenance teams to schedule interventions during planned downtime windows rather than reacting to failures mid-shift. This proactive approach reduces mean time to repair (MTTR), extends equipment service life, and keeps energy consumption within design parameters by preventing degraded-mode operation.

All units are shipped after full functional testing and are backed by a 12-month warranty, with in-stock availability ensuring minimal lead times for replacement or expansion projects.

Q1: How does the AN-X2-AB-DHRIO contribute to measurable energy savings on the production line? By exposing DH+ and RIO device data to EtherNet/IP-based energy management systems and SCADA platforms, the gateway enables demand-based load control — allowing PLCs to de-energize non-critical motors, drives, and I/O devices during low-production periods. This reduces idle energy consumption and peak demand charges without requiring legacy controller replacements.

Q2: Which Allen-Bradley controllers and drive systems are compatible with the AN-X2-AB-DHRIO? The gateway is compatible with Allen-Bradley PLC-5, SLC 500, and MicroLogix controllers on the DH+ side, and supports up to 32 RIO adapter nodes. On the EtherNet/IP side, it integrates with ControlLogix and CompactLogix platforms, as well as PowerFlex VFDs, Kinetix servo drives, and PowerMonitor energy metering modules that support EtherNet/IP communication.

Q3: Can the AN-X2-AB-DHRIO replace an existing DH+ gateway without reprogramming the legacy PLC? Yes. The AN-X2-AB-DHRIO is designed as a transparent bridge — it maps DH+ node addresses and RIO rack/group/slot configurations to EtherNet/IP tags without requiring changes to the legacy PLC program. Configuration is performed via a web browser interface, and ProSoft's ANX configuration utility provides node mapping templates to accelerate commissioning.

Q4: What testing and warranty coverage is provided? Every AN-X2-AB-DHRIO unit undergoes full functional testing — including DH+ communication verification, RIO scanner node enumeration, and EtherNet/IP connectivity validation — prior to shipment. Units are covered by a 12-month warranty against manufacturing defects. In-stock inventory ensures fast dispatch for both new installations and warranty replacement scenarios.
