Abstract
With the advancement of Industry 4.0, Programmable Logic Controllers (PLCs) play a central role in modern industrial automation control systems. This paper addresses the issues of slow response, low integration, and high maintenance costs in traditional PLC control systems by proposing an optimized solution based on PLCs. The study aims to enhance system real-time performance, reliability, and maintainability through improvements in PLC system architecture and control algorithms. Specific methods include adopting a distributed I/O structure to improve data transmission efficiency, introducing redundancy design to enhance fault tolerance, developing intelligent diagnostic modules for predictive fault detection, and optimizing ladder logic programming to simplify program structure. Practical application tests at an automotive manufacturing enterprise's production line demonstrate that the optimized system reduces average response time by 35%, increases overall equipment effectiveness by 28%, and decreases downtime due to faults by 41%. This research not only effectively resolves key technical bottlenecks in existing PLC control systems but also provides theoretical foundations and technical support for the intelligent upgrade and transformation of similar enterprises, showcasing significant engineering application value and broad promotion prospects. The findings contribute positively to advancing China’s manufacturing sector towards higher-end and smarter directions, laying a solid foundation for establishing efficient and stable industrial automation production systems.
