摘　　要：定时器在各类编程语言环境中的构造及运用显得越来越重要。STEP7作为西门子PLCS7-300系列的编程语言环境,在工控行业的使用也越来越广泛,它多元化的编程方式,决定了定时器的使用颇为独特。重点介绍了在STEP7编程应用环境中,计时器计时、累加器编程计时、中断编程计时等3种常用的计时编程方法,并且经过实际验证,这3种方法可行适用。It is becoming increasingly important that the timer is always constructed and used in various types of program- ming language environment. As programming environment of the Siemens PLCS7-300 series,the use of STEP7 becomes more and more widely in industry. It has a varied programming way which makes the use of timers rather peculiar in STEP7＂s en- vironment. This article focuses on three commonly used methods ,which are timer timing,accumulator programming timing and interrupt programming timing,in STEP7.h is conclused that these three methods are feasible and applicable after verifi- cation.
