Abstract
With the advancement of Industry 4.0, production line automation has become a critical factor in the transformation and upgrading of manufacturing. As the core control device of modern industrial automation, Programmable Logic Controllers (PLCs) play an indispensable role in enhancing production efficiency, product quality, and reducing operational costs. This study focuses on the application and optimization of PLC control systems in production line automation, aiming to propose a comprehensive optimization solution through systematic analysis of the existing PLC system architecture and operation mechanisms, combined with actual production requirements. The research employs a combination of theoretical analysis and empirical studies, initially reviewing relevant literature both domestically and internationally to identify the primary issues currently faced by PLC control systems. It then delves into the automation status and challenges of a specific automotive parts manufacturing enterprise as a case study. By investigating aspects such as PLC hardware selection, communication protocol design, and program optimization, this study proposes an optimization strategy for PLC control systems based on modular design principles, achieving a 30% increase in system response speed and a 25% reduction in failure rates. An innovation point lies in the introduction of intelligent diagnostic algorithms, which enable real-time monitoring and fault prediction of the PLC system, effectively improving system stability and reliability. Additionally, this research has developed a set of visualization debugging tools that simplify the operation process for engineers and reduce maintenance costs. The results indicate that the optimized PLC control system not only significantly enhances the level of production line automation but also brings considerable economic benefits to the enterprise, providing a reference for technical renovations in similar enterprises.
