Abstract
With the continuous improvement of modern industrial automation, Programmable Logic Controllers (PLC) are being increasingly applied in automated production line control systems. This paper aims to explore the specific applications of PLCs in this field to provide references for related research and practice. By analyzing the current status and trends of PLC technology development both domestically and internationally, and considering the actual requirements of automated production line control systems, a combination of theoretical research and case analysis is employed to thoroughly examine the functional implementation, system architecture design, and integration methods with other equipment of PLCs in automated production line control systems. The study demonstrates that PLCs can effectively enhance production efficiency, reduce failure rates, and simplify maintenance work, exhibiting superior performance in data acquisition and processing, logical operations, and process control. Innovatively, a distributed intelligent control architecture based on PLCs has been proposed, achieving precise control of complex production processes and addressing information transmission bottlenecks present in traditional centralized control systems, thereby improving system reliability and flexibility. Additionally, specialized PLC program modules suitable for specific industries have been developed, enhancing system adaptability. The results indicate that the application of PLCs in automated production line control systems possesses significant advantages, not only meeting the current demands of industrial automation development but also laying a solid foundation for future intelligent manufacturing.
