今天給我們說一個西門子事例——西門子S7-200SMART PLC怎樣實現兩燈交替閃耀

　　我們先來看看這個事例的具體要求：

　　運用定時器Q0.0和Q0.1，當按下發(fā)動按鈕時Q0.0亮，1秒后Q0.0滅，同時Q0.1亮，再過兩秒后Q0.1滅。以此循環(huán)，直到按下中止按鈕，Q0.0和Q0.1全滅

　　首要畫時序圖。再用定時器加比較的辦法會把很多雜亂的東西簡單化

　　時序圖便是表示地址或變量根據時刻的改變而改變的圖形

　　整個占用的時刻為3秒，需要用到100毫秒定時器

　　設：定時器的當時值為X，0≦X﹤10的時候，Q0.0亮；當10≦X﹤30時，Q0.1亮。

　　接下來便是循環(huán)的問題，循環(huán)便是用最后一個狀況作為第一個狀況的發(fā)動條件。

　　定時器PT值為3秒(數值計作30)，運用TNO接通延時定時器，當當時值=設定值，狀況輸出為1時，即定時器狀況位T37=1時，就去復位定時器，再從0開始，這個便是自復位，便是自己復位自己，到了3秒就從0開始。

　　最后整理下編寫程序的思路：

　　1、 啟停操控——輸出發(fā)動標志位，輸出為1，并保持(自鎖)

　　2、 定時器操控——用發(fā)動標志位去接通定時器，讓其作業(yè)

　　3、 比較——0-1秒Q0.0輸出，1-3秒Q0.1輸出

　　此外還有第二種辦法哦，會運用到震蕩電路(閃耀電路)以及兩個定時器交替操控，一個操控接通時刻，一個操控斷開時刻。
