摘要
可编程控制器中的计数器是基本编程元件之一,它容量大、种类多、使用灵活,是程序中常用的编程元件。但是,如何根据不同类型计数器的特点,正确运用计数器编程,则是编程过程中要足够注意的方面。本文以FX2系列可编程控制器为例,从运用的角度介绍了不同类型计数器的运用特点,指出了编写程序应注意的问题。文章最后介绍了计数器的应用例子。
The Programmable counter is one of the basic program elements. Its distinguish features are large capability, variety of kinds, and easy to use. It is a program element usually used. It is very important to use the counters correctly in programming. This article introduced the characteristics of different kinds in various applications through examples of FX2 programmable counter and for attention in programming are pointed out. At the end of this article two application examples of counter are introduced.
