Allen-Bradley 1336F-BRF75-AE-DE Industrial Network Interface for 1336 FORCE Systems

Allen-Bradley 1336F-BRF75-AE-DE: Industrial Data Link for Smart Factory Drive Networks

The Allen-Bradley 1336F-BRF75-AE-DE is a high-performance AC variable frequency drive from Rockwell Automation’s 1336 FORCE Series, engineered to deliver precise motor control and seamless industrial network integration across demanding manufacturing environments. Rated at 75HP (55kW), this drive is purpose-built for applications where real-time data exchange between field devices, PLC controllers, and supervisory systems is mission-critical. Whether deployed in continuous process lines, material handling conveyors, pump stations, or heavy-duty machine tools, the 1336F-BRF75-AE-DE serves as a reliable node in the connected automation architecture of modern smart factories.

At the heart of its connectivity capability is support for Rockwell Automation’s SCANport and DPI (Drive Peripheral Interface) communication architecture, enabling direct integration with Allen-Bradley PLC platforms including the ControlLogix and CompactLogix families. Through these communication channels, the drive participates actively in the plant-wide data flow — transmitting real-time speed feedback, torque references, fault diagnostics, and energy consumption data upstream to SCADA systems and HMI terminals without requiring additional protocol conversion hardware.

Connected Automation Data Flow

In a typical smart factory deployment, the 1336F-BRF75-AE-DE sits at the intersection of the field device layer and the control network layer. Signal acquisition begins at the sensor level — encoders, thermocouples, and proximity switches feed process variables into the drive’s analog and digital I/O terminals. The drive processes these inputs and executes closed-loop speed or torque control, while simultaneously packaging operational data for transmission across the plant network.

When paired with a 1336-GM1 SCANport Gateway Module, the drive gains full DeviceNet connectivity, allowing a ControlLogix L73 PLC to poll drive status at cyclic intervals as short as 10ms. This tight integration means that a 1756-ENBT EtherNet/IP bridge module in the same ControlLogix chassis can relay drive data upstream to a FactoryTalk View SE SCADA server in real time, enabling operators at a PanelView Plus 7 HMI terminal to monitor motor load, output frequency, and fault history without leaving the control room.

For distributed architectures, the 1336F-BRF75-AE-DE integrates naturally alongside FLEX I/O 1794-series remote I/O modules, which handle discrete and analog field signals from sensors and actuators across the production floor. A 1747-SDN DeviceNet Scanner in an SLC 500 rack can manage multiple drives on the same DeviceNet segment, reducing wiring complexity while maintaining deterministic communication. In applications requiring motion coordination, the drive can receive velocity references from a Kinetix 6500 servo drive via the ControlLogix motion planner, ensuring synchronized multi-axis operation across conveyor and positioning systems.

Edge-level data aggregation is handled by Stratix 5700 managed industrial Ethernet switches, which segment drive traffic from office IT networks while providing IGMP snooping and QoS prioritization to guarantee low-latency delivery of drive diagnostics to the SCADA layer. This network architecture supports remote diagnostics via FactoryTalk AssetCentre, where maintenance engineers can retrieve historical fault logs, parameter change records, and energy trend data for predictive maintenance planning — all without physical access to the drive cabinet.

Solving Data Isolation in Industrial Sites

Many industrial facilities operating legacy drive infrastructure face a common challenge: drives that run reliably in isolation but contribute nothing to plant-wide visibility. The 1336F-BRF75-AE-DE directly addresses this data isolation problem through its native SCANport and DPI communication architecture, which eliminates the need for third-party protocol converters in Rockwell Automation environments.

Where mixed-protocol environments exist — for example, where Modbus RTU sensors feed data alongside DeviceNet drives — the 1336F-BRF75-AE-DE can be integrated via a 1203-GU6 Universal Gateway, which bridges SCANport to multiple fieldbus protocols. This gateway approach allows legacy instrumentation to coexist with modern EtherNet/IP infrastructure, enabling a phased modernization strategy without full system replacement.

Production line transparency is achieved by mapping drive parameters — output current, DC bus voltage, fault codes, and run-time hours — directly into the ControlLogix tag database via the DeviceNet scanner. These tags are then exposed to FactoryTalk View SE dashboards, giving production managers real-time KPI visibility including OEE contributions from individual drive nodes. Alarm management is handled at the SCADA level, with fault escalation logic configured in RSLogix 5000 to trigger email or SMS notifications when drive fault codes exceed defined thresholds.

System expansion is straightforward: additional 1336 FORCE drives can be added to an existing DeviceNet segment (up to 64 nodes per segment) without reconfiguring the network backbone. Each new drive node is auto-detected by the DeviceNet scanner and mapped to a new tag block in the PLC, reducing commissioning time from days to hours. This scalability makes the 1336F-BRF75-AE-DE a long-term investment for facilities planning phased capacity expansion.

All units supplied by ZYPLC undergo pre-shipment functional testing, including communication port verification, parameter upload/download checks, and insulation resistance testing. Each drive ships with a 12-month warranty covering manufacturing defects and communication hardware failures, with technical support available throughout the warranty period.

Industrial Connectivity FAQ

Q1: What communication protocols does the 1336F-BRF75-AE-DE support natively?
The drive natively supports Rockwell Automation’s SCANport and DPI protocols. DeviceNet, ControlNet, and Remote I/O connectivity are available through plug-in adapter modules such as the 1336-GM1 or 1203-GU6 gateway, enabling integration into virtually any Rockwell Automation control architecture without additional protocol conversion hardware.

Q2: How is communication latency managed in a DeviceNet network with multiple 1336 FORCE drives?
DeviceNet uses a producer-consumer communication model with configurable Expected Packet Interval (EPI) settings. For the 1336F-BRF75-AE-DE, EPI values as low as 10ms are achievable in polled I/O mode, ensuring deterministic data delivery even in networks with up to 64 nodes. Network load should be balanced by segmenting high-priority drives onto dedicated DeviceNet trunks managed by separate scanner modules.

Q3: Can the 1336F-BRF75-AE-DE be integrated into a FactoryTalk View SE SCADA system without additional middleware?
Yes. When connected via DeviceNet to a ControlLogix PLC with an EtherNet/IP bridge module, all drive parameters are available as standard PLC tags accessible by FactoryTalk View SE through the RSLinx Enterprise OPC server. No additional middleware or custom drivers are required, and the integration is fully supported within the standard Rockwell Automation software ecosystem.

Q4: What does the 12-month warranty cover, and what pre-shipment testing is performed?
The 12-month warranty covers manufacturing defects, communication port hardware failures, and power electronics faults under normal operating conditions. Prior to shipment, each 1336F-BRF75-AE-DE unit undergoes functional testing including power-on verification, communication port handshake testing, parameter read/write validation, and insulation resistance measurement. Test records are available upon request and accompany each unit’s documentation package.
