摘要
在PLC编程练习的教学过程中,学生对于一些逻辑关系复杂的问题较难掌握和上手。分析了传统经验设计法存在着设计复杂、可读性差等缺点,针对这些问题叙述了步进顺序设计法的原理,以逻辑关系比较复杂的控制问题为例,具体介绍了步进顺序设计方法的实际应用。以步进顺序思想为基础的编程方法使学生只用掌握S7-300PLC的基本编程语言后,就可对比较复杂的控制问题进行编程。
This paper introduces the wide application of PLC in the process of teaching PLC programming for some complex logical problems, students learn programming too more difficult to grasp and use. This article analyses that the traditional experience design method of PLC programming has the disadvantages of complex design and poor readability. To solve these problems, this paper describes the principle of step sequence design method. Based on a complex logical example, this paper introduces the practical application of the step sequence design method. It proves that after mastering the basic S7-300PLC programming language, the students can program the complicated control problems by using the method of step sequence PLC programming.
