基于常规交通灯控制PLC的时间顺序控制编程方法

Realization Method to Controlling Traffic Signals by PLC a Study to Time Sequence Controlling Programming Method

交通信号灯控制是典型的时间顺序控制,利用PLC可以简便、准确地实现该类控制,构建该控制系统的主要任务是程序设计。本文以日本松下电工FP0-C32型小型PLC为例,介绍了实现常规交通灯控制的四种编程方法。

The Control of traffic signals is a typical time sequence controlwhich can be simply realized by PLC The main task of PLC to realizing the control system is programming.The article takes NAIS FP0-C32 PLC as exampleand discusses four programming realization methods to controlling general traffic signals.
