摘要
本文从实际应用出发,通过使用单片机内部计数/定时器和可编程技术器阵列PCA[1],兼顾低速输入信号的稳定性和高速信号的实时性,重点阐述一种能对输入信号有效脉冲宽度限定以及高速A、B相脉冲计数的PLC基本功能的开发方法。
From the practical application, by using the microcontroller internal counter / timer and programmable technology array PCA, the stability of both low-speed input signal in real time and high-speed signals and focuses on an input signal can limit the effective pulse width and high-speed A~ B phase pulse counting method of developing the basic functions of PLC.
