摘　　要：本文就电气自动化领域广泛使用的可编程序控制器的高速计数器的应用作了详细的说明。由于高速计数器计数频率高,并能跳出可编程序控制器的循环扫描周期,在实际应用中使用价值很高。本文通过举例详细说明了高速计数器与编码器的匹配、最高频率的选取、相关指令与中断的组合运用。This paper made a detailed explanation on the widely used high speed counter of programmable controller in the field of electrical automation. Due to the high frequency of high speed counter and the situation that it can jump out of the circular scanning cycle of programmable controller, it is of great value in practical application. Through examples, this paper detailed the match between high speed counter and coder, the selection of the highest frequency, and the combination and application of related instruction and interrupt.

关 键 词：可编程序控制器 高速计数器 最高频率 中断
