Excel流程文本转PLC流程图的设计与实现

PLC编程语言中,流程图编程因其简单易懂而广泛被使用,在工程设计文档中,用户多以表格、文本等形式来描述控制逻辑的过程,而不是PLC能够识别的控制流程图。针对这一问题,提出了将表格、文本中的有效信息提取出来,并能够快速、准确地生成PLC能够识别的控制流程图的实现方法。

In PLC programming language,flow chart programming is widely used because it is easy to understand.In engineering design documents,users usually describe the process of control logic in the form of tables and text,rather than the control flow chart that can be recognized by PLC.In order to solve this problem,this paper proposes a method to extract the effective information from the form and text,and to quickly and accurately generate the control flow chart that can be recognized by PLC.
