Abstract

This study designs and implements an integrated intelligent production line control system based on Siemens S7-1500 PLC and PROFINET industrial Ethernet. The system employs the S7-1500 as the core controller, integrating devices such as V90 servo drives, G120 frequency converters, and HMI to establish a distributed-centralized control network. Through the TIA Portal platform, this study completes the hardware configuration and software programming, and the implementation of programs such as servo drive systems, frequency converters, and IO-Link-based RFID data read/write is presented. The sequential flow charts are used to illustrate the automatic control process of the intelligent production line, and a modular HMI for human-machine interaction is designed. Application results demonstrate that the system effectively addresses system integration issues, achieves automation, informatization, and flexibility throughout the entire production process, and significantly enhances the control efficiency and reliability of the production line.
