三菱FX2N系列PLC中定时器扩展应用的探索

Research on Extended Application of Timer in Mitsubishi FX2N Series PLC

基于三菱FX2N系列PLC中定时器典型应用程序的结构组成,阐述了其工作原理及应用场合,总结了定时器与定时器、定时器与计数器组成的定时扩展电路、产生连续脉冲信号的振荡电路、用于自动循环的自复位电路的几种形式,为提高定时器应用程序的设计能力与应用能力提供一定的理论基础。

Based on the structure of timer typical application program in Mitsubishi FX2N series PLC,its working principle and application occasions were expounded,several forms of timer and timer,timer and counter composed of timing expansion circuit,oscillation circuit to generate continuous pulse signal,and self reset circuit used for automatic cycle were summarized,so as to improve the design ability of timer application program and application ability to provide a certain theoretical basis.
