摘要
分析了影响ＰＬＣ控制式的电气系统可靠性的主要因素，并以自动焊接机为例，提出了利用 ＰＬＣ软元件（如内部计时器等）来解决它们的设计方法，此方法经济、实用，对提高ＰＬＣ控制电 气系统可靠性具有普遍意义和实用价值。
In this paper, analyzed are the reliability factors of the electrical systems with PLCs in machine tools. For example, we approach to utilize the soft components (such as Internal timers) to improve the reliability of the automatic welding machine. This manner is economical and practicable for kinds of the electrical systems with PLCs.
