Allen-Bradley 9324-RLD700NXENE Industrial Network Interface for FactoryTalk Systems

Allen-Bradley 9324-RLD700NXENE: Industrial Data Link and Smart Factory Network Interface for FactoryTalk Systems

In modern industrial automation, the ability to move data reliably across every layer of a control system — from field-level sensors and drives to SCADA dashboards and enterprise MES platforms — defines the operational intelligence of a smart factory. The Allen-Bradley 9324-RLD700NXENE, the full-featured RSLinx Classic Gateway edition, serves as the critical communication bridge that connects Rockwell Automation PLCs, remote I/O modules, HMI terminals, and supervisory systems into a unified, real-time data network. Rather than functioning as a standalone software utility, this product is the connective tissue of a FactoryTalk-based control architecture — enabling protocol translation, device discovery, data routing, and remote diagnostics across heterogeneous industrial networks.

RSLinx Classic Gateway (9324-RLD700NXENE) supports an extensive range of industrial communication protocols including EtherNet/IP, DeviceNet, ControlNet, DH+, DH-485, DF1, and Remote I/O. This multi-protocol capability allows a single installation to serve as the communication server for the entire plant floor, eliminating the need for separate gateways or protocol converters at each network boundary. Whether the upstream system is a FactoryTalk View SE SCADA station, a third-party OPC client, or a custom MES application, 9324-RLD700NXENE provides the standardized OPC DA and DDE interface layer that makes data universally accessible.

Connected Automation Data Flow

The value of 9324-RLD700NXENE becomes most apparent when viewed within the full data flow of a layered automation system. At the field level, sensors, encoders, and actuators connect to Allen-Bradley 1734 POINT I/O modules or 1756 ControlLogix I/O cards distributed across the machine frame. These field signals are processed by a 1756-L85E ControlLogix CPU or a 1769-L33ER CompactLogix controller, which executes the control logic and generates real-time process data. RSLinx Classic Gateway acts as the communication server that exposes this controller data to all upstream clients simultaneously — without requiring each client to maintain its own direct connection to the PLC.

On the network layer, the 1783-BMS10CGL Stratix 5700 managed Ethernet switch provides the backbone infrastructure, segmenting traffic between the control network and the information network while maintaining deterministic EtherNet/IP performance. RSLinx Classic Gateway sits at this boundary, translating between the EtherNet/IP device-level protocol and the OPC DA interface consumed by SCADA and HMI applications. A FactoryTalk View SE station running on the supervisory network subscribes to tag data through RSLinx, displaying real-time process values, alarm states, and trend data to operators without any direct PLC polling overhead.

For legacy network integration, 9324-RLD700NXENE supports DH+ and DF1 serial connections through the 1784-U2DHP USB-to-DH+ adapter, allowing older SLC 500 and PLC-5 controllers to participate in the same unified data network as modern ControlLogix systems. This backward compatibility is critical in brownfield plants where capital equipment cannot be replaced but operational visibility must be extended to modern SCADA and MES platforms. The 1747-L553 SLC 5/05 Ethernet controller, for example, can be browsed and monitored through RSLinx alongside a ControlLogix rack, presenting a unified device tree to the SCADA operator.

At the drive and motion layer, PowerFlex 755 variable frequency drives connected via EtherNet/IP are fully discoverable through RSLinx Classic Gateway, enabling FactoryTalk View SE to display drive speed, current, fault codes, and energy consumption in real time. Similarly, Kinetix 5700 servo drives integrated into a Studio 5000 motion project are accessible through the same RSLinx OPC server instance, consolidating motion diagnostics into the plant-wide SCADA view. This eliminates the data isolation that typically exists between motion control networks and process control SCADA systems.

Remote diagnostics and predictive maintenance workflows depend on the stability of the RSLinx communication layer. When a 1756-EN2T EtherNet/IP communication module in a remote ControlLogix chassis reports a connection timeout, RSLinx Classic Gateway propagates this fault status to the SCADA alarm server, triggering an alert to the maintenance team before a production stoppage occurs. This proactive fault visibility, enabled by the continuous OPC subscription model of 9324-RLD700NXENE, reduces unplanned downtime and supports condition-based maintenance strategies across the entire connected plant.

Solving Data Isolation in Industrial Sites

One of the most persistent challenges in industrial automation is the fragmentation of data across incompatible protocols, isolated network segments, and legacy equipment that was never designed for connectivity. The 9324-RLD700NXENE directly addresses these challenges by providing a single, stable communication server that bridges every protocol layer in a Rockwell-based architecture.

Protocol Unification: Plants running a mix of EtherNet/IP, ControlNet, DeviceNet, and legacy DH+ networks no longer need separate OPC servers or protocol converters for each network type. RSLinx Classic Gateway manages all protocol drivers within a single application instance, presenting a unified OPC namespace to SCADA, HMI, and MES clients. This dramatically simplifies the data integration architecture and reduces the number of communication failure points.

Production Line Transparency: With RSLinx Classic Gateway serving as the OPC backbone, FactoryTalk Historian can subscribe to thousands of PLC tags across multiple controllers simultaneously, building a continuous time-series database of production KPIs, quality parameters, and equipment health metrics. This data foundation enables real-time OEE dashboards, shift reports, and long-term trend analysis without any custom programming at the PLC level.

Remote Monitoring and Diagnostics: In multi-site manufacturing environments, RSLinx Classic Gateway can be configured to serve OPC data to remote SCADA clients over a secure WAN connection, enabling centralized monitoring of geographically distributed production lines. Maintenance engineers can use RSLinx’s RSWho browser to remotely identify connected devices, check communication status, and diagnose network faults without traveling to the plant floor.

System Scalability: As production capacity expands and new equipment is added to the plant network, RSLinx Classic Gateway scales to accommodate additional PLC nodes, I/O modules, and communication drivers without requiring a new communication server installation. The Gateway edition’s multi-client architecture supports concurrent OPC connections from multiple SCADA stations, historian servers, and MES applications, making it the long-term communication infrastructure investment for growing smart factory deployments.

Industrial Connectivity FAQ

Q1: Does 9324-RLD700NXENE support simultaneous connections from multiple SCADA and HMI clients?
Yes. The Gateway edition of RSLinx Classic is specifically designed for multi-client environments. It functions as an OPC DA server that allows multiple concurrent client connections — including FactoryTalk View SE, third-party SCADA platforms, FactoryTalk Historian, and custom OPC clients — to access PLC data simultaneously through a single RSLinx server instance. This eliminates the need for each client to maintain its own direct PLC connection, reducing network load and simplifying device management.
