Abstract
With the continuous improvement of modern industrial automation, mechatronic control systems are increasingly applied in manufacturing. Among these, PLC-based control systems have become a research focus due to their high reliability, flexibility, and maintainability. This study aims to design and implement a PLC-based mechatronic control system to meet the precise control requirements in complex industrial environments. By analyzing the shortcomings of existing systems, an integrated and modular control architecture is proposed, utilizing Siemens S7-1200 series PLC as the core controller, combined with a touch screen for human-machine interaction, and incorporating Profibus-DP fieldbus technology to optimize data transmission efficiency. The STEP 7 software was used for programming and debugging, with functional customization for specific application scenarios such as material handling and processing production lines, effectively integrating motor drive and sensor detection functions. Experimental results indicate that the system operates stably, demonstrating superior performance in response speed and positioning accuracy compared to traditional solutions. The innovation lies in the deep integration of advanced communication protocols with PLC control, enhancing system compatibility and scalability while simplifying hardware connections and reducing fault rates. This provides new ideas and technical references for similar project developments, promoting the advancement of mechatronic integration.
