With the development of industrial, PLC-based automated production lines are widely used, but there are many challenges to improve efficiency. This paper explains the optimization of PLC control system and proposes improvement strategies from selection, program design, communication network and other aspects. The layout of the production line and process optimization are discussed, and the principles of equipment layout and the methods of process flow are analyzed. The fault diagnosis and maintenance technologies are researched, and the construction of fault diagnosis system and maintenance scheme are introduced. The integration of intelligent control technology is mentioned, and its direction is described. Through this key technology analysis, it provides comprehensive technical support and theoretical reference for improving the efficiency of PLC automated production line, and promotes the efficient development of industrial automation.
