To address the modern manufacturing demands of small-batch, multi-variant production, STMicroelectronics has developed an intelligent flexible manufacturing solution integrating IO-Link communication, advanced motor control, and PLC technologies.
This solution leverages a magnetic levitation flexible conveying system that achieves high-precision, low-noise, and maintenance-free operation through contactless material transfer. The system employs a dual-motor servo control solution based on the STSPIN32G4 motor driver, enabling a single controller to drive two motors simultaneously. By sharing current detection circuits and EtherCAT communication links, this architecture reduces hardware costs compared to traditional "one-controller-per-motor" configurations while minimizing the number of EtherCAT slaves controlled by the PLC.

The PLC system utilizes the STM32MP257 microprocessor with the CODESYS soft PLC platform, delivering mid-to-high-end control capabilities adaptable to diverse production line requirements. IO-Link devices incorporating the L6364 transceiver further enhance intelligence integration, supporting digital I/O modules, smart sensors, and actuators. This standardized protocol enables real-time device communication while maintaining compatibility with existing automation ecosystems and reducing development complexity.

Key advantages of the solution include:
1. Cost Optimization: The dual-motor-per-controller design reduces motor control costs through shared hardware architecture.
2. Flexible Scalability: Modular IO-Link components enable rapid production line upgrades and reconfiguration.
3. Universal Control: The CODESYS soft PLC platform simplifies development processes.
4. Precision Flexibility: The magnetic levitation transmission system ensures high-accuracy, adaptable control for customized production.

STMicroelectronics' comprehensive product portfolio—spanning motor drivers, MPUs, and industrial communication chips—ensures end-to-end integration across the automation chain. This solution improves production line changeover speeds while fully complying with Industry 4.0 standards. By converging motion control, IoT connectivity, and adaptive automation technologies, STMicroelectronics empowers manufacturers to achieve efficient flexible production while maintaining cost-effectiveness and reliability.
