摘要
PLC技术的难点是根据工艺流程和控制要求编写控制程序。介绍了PLC技术编程的新方法—运用数字电路的逻辑分析方法进行程序设计。采用数字逻辑法编程的特点是逻辑关系非常简单、程序结构非常简洁,编程费时很短,无需绞尽脑汁,还能节省PLC的输入点,优点显著。
The difficulty of PLC technology is based on the technological process and control requirements to write control pro- gram.This paper introduces a new method - PLC programming using digital logic circuit analysis program.The characteris- tics of digital logic programming is very simple logical relationship,the program structure is very simple,programming time is very short,no rack one＇s brains,but also save the input point of PLC,significant advantages.
