Product Details

320087-A06 Product Description

The Allen-Bradley 320087-A06 is a precision-engineered industrial network interface board designed for PowerFlex variable frequency drive systems. In the context of modern smart factory architecture, this module serves as a critical data link between field-level drive hardware and upper-level control and monitoring systems. Whether deployed in a discrete manufacturing line, a continuous process plant, or a hybrid automation environment, the 320087-A06 enables seamless protocol bridging, real-time data exchange, and remote diagnostic capability across the full automation stack — from sensor-level signal acquisition all the way to enterprise SCADA dashboards and MES platforms.

As industrial facilities accelerate their transition toward Industry 4.0 connectivity, the demand for reliable, multi-protocol drive communication modules has never been greater. The 320087-A06 addresses this need by providing a stable, tested, and immediately deployable network interface solution for PowerFlex 400, PowerFlex 525, and PowerFlex 755 series drives, ensuring that drive status, speed reference, fault codes, and energy consumption data are continuously available to the control layer without communication gaps or data latency.

In a fully connected smart factory, the Allen-Bradley 320087-A06 occupies a pivotal position in the data flow architecture. At the field level, sensors and encoders feed real-time process variables — motor speed, torque, current draw, and thermal status — directly into the PowerFlex drive. The 320087-A06 network interface board then packages this data and transmits it upstream via EtherNet/IP or DeviceNet to a ControlLogix or CompactLogix PLC controller, where ladder logic and function block programs process the values and issue closed-loop control commands back to the drive.

From the PLC layer, data flows further upstream to a PanelView Plus HMI terminal, where operators monitor drive status, acknowledge alarms, and adjust setpoints in real time. Simultaneously, the same data stream is forwarded to a FactoryTalk View SE SCADA server, enabling plant-wide visualization, trend logging, and alarm management across multiple production zones. For facilities running distributed control architectures, the 320087-A06 integrates cleanly with 1734 POINT I/O and 1756 ControlLogix I/O modules, allowing remote I/O nodes to participate in the same EtherNet/IP network without requiring separate communication infrastructure.

At the edge layer, an industrial edge gateway — such as those running FactoryTalk Edge or third-party OPC-UA middleware — collects the drive data published by the 320087-A06 and forwards it to cloud analytics platforms or on-premise MES systems. This enables energy consumption tracking, OEE calculation, and predictive maintenance scheduling based on actual drive operating hours and fault history. PowerFlex 755 drives equipped with the 320087-A06 can also interface with PowerFlex 523 and PowerFlex 527 drives on the same network segment, creating a unified drive communication backbone across conveyor systems, pump stations, compressor banks, and HVAC control loops.

For applications requiring protocol conversion between legacy serial networks and modern Ethernet infrastructure, the 320087-A06 supports DH-485 and Modbus RTU alongside EtherNet/IP, making it an effective bridge between older Allen-Bradley SLC 500 or MicroLogix controllers and contemporary ControlLogix-based control systems. This multi-protocol flexibility reduces the need for standalone protocol converters or additional gateway hardware, simplifying the network topology and lowering total system cost.

Many industrial sites operate with fragmented communication architectures — legacy drives running proprietary serial protocols, newer PLCs expecting Ethernet-based data, and SCADA systems unable to reach field devices without manual data entry or periodic polling. The Allen-Bradley 320087-A06 directly addresses these data gaps by providing a standardized, plug-in network interface that eliminates the communication barrier between PowerFlex drives and the broader automation network.

Protocol inconsistency is one of the most common sources of data islands in manufacturing environments. When a PowerFlex drive cannot communicate its fault status or speed reference to the PLC in real time, operators are forced to rely on local drive keypads or periodic manual inspections — both of which introduce latency, human error, and unplanned downtime. The 320087-A06 resolves this by enabling continuous, bidirectional data exchange between the drive and the control system, ensuring that fault codes, output frequency, DC bus voltage, and motor current are always visible at the SCADA and HMI level.

Remote diagnostics capability is another critical benefit. With the 320087-A06 installed, maintenance engineers can interrogate drive parameters, reset faults, and adjust acceleration/deceleration ramps from a remote workstation via Studio 5000 or FactoryTalk Diagnostics — without requiring physical access to the drive cabinet. This is particularly valuable in hazardous environments, high-bay installations, or geographically distributed facilities where on-site intervention is costly and time-consuming.

For production line transparency, the 320087-A06 enables alarm tracking and event logging at the drive level, feeding structured fault data into the SCADA historian for root cause analysis and compliance reporting. System expansion is equally straightforward: additional PowerFlex drives can be added to the EtherNet/IP network by installing the same 320087-A06 interface card, maintaining a consistent communication architecture as production capacity grows.

Q1: What communication protocols does the Allen-Bradley 320087-A06 support? The 320087-A06 supports EtherNet/IP, DeviceNet, ControlNet, DH-485, and Modbus RTU, making it compatible with a wide range of Rockwell Automation PLC platforms and third-party SCADA systems. This multi-protocol capability ensures the module can be deployed in both legacy and modern network environments without additional gateway hardware.

Q2: Is the 320087-A06 compatible with all PowerFlex drive series? The 320087-A06 is designed as a plug-in option card for PowerFlex series drives including PowerFlex 400, PowerFlex 525, and PowerFlex 755. Compatibility should be verified against the specific drive firmware version and option card slot configuration. Our technical team can assist with compatibility confirmation prior to shipment.

Q3: How does the 320087-A06 support remote diagnostics and network stability? Once installed, the 320087-A06 enables continuous parameter monitoring and fault reporting via the drive's EtherNet/IP or DeviceNet connection. Maintenance personnel can access drive diagnostics remotely through Studio 5000 or FactoryTalk Diagnostics, reducing mean time to repair (MTTR) and minimizing unplanned downtime. The module is designed for 24/7 industrial operation with high EMI immunity and stable network throughput.

Q4: What does the 12-month warranty cover, and has the unit been tested before shipment? Every Allen-Bradley 320087-A06 unit supplied by NANKMOS undergoes functional testing prior to shipment to verify communication integrity, parameter read/write capability, and network handshake performance. The 12-month warranty covers manufacturing defects and functional failures under normal operating conditions. In-stock units are available for immediate dispatch with fast global shipping to support urgent maintenance and production continuity requirements.
