Product Details

1336F-MCB-SP1C Product Description

The Allen-Bradley 1336F-MCB-SP1C is the main control PC board for the FORCE Series variable frequency drive platform, engineered to serve as the central intelligence layer in industrial network architectures. Designed for demanding production environments, this board governs drive logic, feedback processing, and communication handshaking between field-level devices and upper-layer control systems. In smart factory deployments, the 1336F-MCB-SP1C functions as the critical data node that bridges motor control hardware with SCADA supervisory layers, enabling real-time visibility, remote diagnostics, and closed-loop automation across the entire production line.

Industrial connectivity begins at the signal level. The 1336F-MCB-SP1C interfaces directly with encoder feedback modules, analog I/O expansion cards, and digital I/O assemblies mounted within the FORCE Series drive chassis. These signals — speed references, torque feedback, fault codes, and thermal status — are processed on-board and made available to upstream controllers via the drive's communication adapter slot. When paired with a 1336-GM1 or 1336-GM6 communication adapter, the board supports DeviceNet or Remote I/O protocol, enabling the Allen-Bradley PLC-5 or SLC 500 controller family to poll drive parameters at deterministic scan rates. This tight integration eliminates the latency and data loss that plague analog-only wiring schemes, replacing them with a structured, packet-based data flow that supports both cyclic status reporting and acyclic parameter writes.

At the network transport layer, the 1336F-MCB-SP1C participates in a broader industrial Ethernet or fieldbus topology. In facilities running ControlLogix or CompactLogix platforms, the drive data collected by the 1336F-MCB-SP1C is aggregated through an EtherNet/IP-capable gateway — such as the 1756-ENBT or a third-party protocol converter — and forwarded to the plant SCADA server. This architecture supports Ignition SCADA, FactoryTalk View SE, and similar HMI platforms, where operators monitor drive speed, output current, DC bus voltage, and fault history on live dashboards. The structured data path from the 1336F-MCB-SP1C through the communication adapter, across the fieldbus, and into the SCADA historian creates a complete audit trail for predictive maintenance and energy optimization programs.

Remote diagnostics represent one of the highest-value capabilities enabled by the 1336F-MCB-SP1C's network integration. Maintenance engineers can query drive fault queues, read parameter tables, and issue controlled stop or reset commands from a remote HMI terminal or engineering workstation without physical access to the drive cabinet. This is particularly valuable in hazardous or hard-to-reach installations — pump stations, compressor rooms, elevated conveyor drives — where unplanned downtime carries significant safety and production cost. The board's fault logging architecture captures timestamped fault events that can be exported to the SCADA historian for trend analysis, enabling maintenance teams to identify recurring fault patterns before they escalate to unplanned stops.

System expansion is straightforward within the FORCE Series ecosystem. The 1336F-MCB-SP1C is compatible with the full range of FORCE Series option cards, including the 1336F-B030 power structure, analog reference cards, and encoder feedback modules. As production lines scale — adding conveyor zones, pump stages, or additional motor axes — additional FORCE Series drives with 1336F-MCB-SP1C boards can be added to the DeviceNet or Remote I/O network segment without architectural redesign. Each new node is automatically recognized by the PLC scanner card, and its parameter set can be pre-loaded from the controller program, reducing commissioning time to minutes per drive.

Outgoing quality testing at NANKMOS covers functional verification of all control board logic paths, communication adapter interface continuity, and parameter memory integrity before shipment. Each 1336F-MCB-SP1C is tested against OEM reference specifications to confirm correct operation of the PWM output stage, analog input scaling, and fault relay outputs. Units are shipped with anti-static packaging and humidity indicators to protect sensitive board components during international transit. Stock is maintained on-hand for immediate dispatch, supporting urgent replacement requirements in facilities where drive downtime directly impacts production throughput.

A representative smart factory data flow built around the 1336F-MCB-SP1C begins at the motor shaft. Encoder feedback from the driven motor is wired directly to the FORCE Series drive's encoder input, where the 1336F-MCB-SP1C processes speed and position data in real time. Simultaneously, analog process signals — pressure transmitters, flow sensors, or temperature probes — feed into the drive's analog input terminals, allowing the board to implement closed-loop PID control without requiring a separate PLC scan cycle for the inner loop.

The 1336F-MCB-SP1C communicates upstream via a 1336-GM1 DeviceNet adapter installed in the drive's option slot. On the DeviceNet segment, a 1771-SDN Scanner Module in a PLC-5 rack polls the drive at a 10 ms scan rate, reading speed feedback, output current, and fault status into the PLC data table. The PLC-5 program uses this data to coordinate the FORCE Series drive with adjacent automation nodes — including remote I/O racks carrying 1771-IFE analog input modules for process instrumentation and 1771-OFE analog output modules driving control valves.

At the supervisory layer, a ControlLogix gateway with a 1756-ENBT EtherNet/IP bridge module aggregates data from multiple DeviceNet segments and publishes it to the plant network. The FactoryTalk View SE HMI server subscribes to drive tags — including 1336F-MCB-SP1C fault codes, DC bus voltage, and output frequency — and displays them on operator faceplates. Alarm thresholds configured in the HMI trigger notifications when drive parameters exceed safe operating limits, enabling operators to respond before a fault trip occurs.

For facilities integrating third-party SCADA platforms such as Ignition, a protocol gateway — such as a Moxa MGate or ProSoft MVI56-DFNT module — bridges the DeviceNet data to Modbus TCP or OPC-UA, making the 1336F-MCB-SP1C's drive data accessible to any SCADA client on the plant network. This architecture supports multi-vendor environments where Allen-Bradley drives coexist with Siemens SINAMICS or ABB ACS series drives on the same supervisory network, with each drive's data normalized into a common tag structure for unified visualization and reporting.

Edge analytics nodes — such as an industrial PC running FactoryTalk Analytics or a Cisco IE3400 industrial switch with embedded telemetry — can tap the EtherNet/IP data stream to perform local anomaly detection on drive waveforms, flagging bearing wear or rotor imbalance signatures before they appear as hard faults on the 1336F-MCB-SP1C fault queue. This edge-to-cloud data path completes the smart factory connectivity loop, from the motor shaft through the control board, across the fieldbus, into the SCADA historian, and up to cloud-based predictive maintenance dashboards.

Protocol Fragmentation: Many production sites operate mixed-protocol environments where legacy Allen-Bradley Remote I/O segments coexist with newer DeviceNet or EtherNet/IP infrastructure. The 1336F-MCB-SP1C, through its interchangeable communication adapter slot, allows the same drive hardware to participate in either protocol environment. Replacing a 1336-GM6 Remote I/O adapter with a 1336-GM1 DeviceNet adapter migrates the drive to the newer network without replacing the drive or the control board, protecting capital investment while enabling protocol modernization.

Data Silos: Drive data trapped in standalone VFD units — accessible only via the drive keypad — creates blind spots in production monitoring. The 1336F-MCB-SP1C's network integration eliminates this silo by making all drive parameters available to the PLC and SCADA system in real time. Energy consumption data, run-hour counters, and fault histories that were previously invisible to the plant historian are now captured automatically, enabling energy audits, OEE calculations, and maintenance scheduling based on actual drive operating data.

Remote Monitoring Gaps: In multi-site or geographically distributed facilities, local drive inspection is impractical. The 1336F-MCB-SP1C's network-connected architecture allows remote engineers to read drive status, acknowledge faults, and adjust speed references from a central control room or via VPN-connected engineering workstation. This capability reduces travel costs, accelerates fault response, and supports 24/7 monitoring without requiring on-site staffing at every drive location.

Production Line Transparency: Integrating the 1336F-MCB-SP1C into the plant SCADA system provides production managers with real-time visibility into drive-controlled processes — conveyor speeds, pump flow rates, compressor pressures — that were previously reported only through manual rounds. Automated alarm escalation, shift reports generated from historian data, and KPI dashboards built on drive telemetry transform reactive maintenance into a proactive, data-driven operation.

Q: What communication protocols does the 1336F-MCB-SP1C support?A: The 1336F-MCB-SP1C supports DeviceNet and Allen-Bradley Remote I/O protocols via interchangeable communication adapters (1336-GM1 for DeviceNet, 1336-GM6 for Remote I/O). EtherNet/IP connectivity is achievable through an upstream protocol gateway, enabling integration with modern ControlLogix-based networks and third-party SCADA platforms.

Q: Is the 1336F-MCB-SP1C compatible with ControlLogix and CompactLogix controllers?A: Yes. While the FORCE Series drive was originally designed for PLC-5 and SLC 500 platforms, the 1336F-MCB-SP1C can be integrated into ControlLogix and CompactLogix systems via a DeviceNet scanner module (1756-DNB or 1769-SDN) or through a protocol gateway bridging DeviceNet to EtherNet/IP. This allows the drive to participate in modern Studio 5000-based control architectures.

Q: How does NANKMOS verify the 1336F-MCB-SP1C before shipment?A: Each unit undergoes functional testing covering control logic paths, communication adapter interface continuity, PWM output stage verification, analog input scaling, and fault relay operation. Units are tested against OEM reference specifications and shipped with anti-static and humidity-protective packaging. A 12-month warranty covers defects in materials and workmanship from the date of shipment.

Q: Can the 1336F-MCB-SP1C be used in a mixed-vendor drive environment?A: Yes. Through protocol gateways such as the ProSoft MVI56-DFNT or Moxa MGate series, the 1336F-MCB-SP1C's DeviceNet data can be translated to Modbus TCP or OPC-UA, making it accessible alongside drives from other manufacturers on a unified SCADA or HMI platform. This supports multi-vendor smart factory architectures without requiring a homogeneous drive fleet.
