摘要
本文以台车的PLC顺序控制编程为例,介绍了移位指令实现PLC顺序控制程序的编程思想及方法,并对复杂流程的顺序控制系统的程序设计进行了探讨。该方法思路清晰,步骤明确,易于接受和掌握。
Based on the design of control procedures of trolley,this paper introduces the ideas and methods of Sequence Control Program of PLC by shift instruction,and presents a general design method for complex process sequence control system.This method is concise and easy to learn.
