步進(jìn)順控法：步進(jìn)順控法是在順控指令的配合下設(shè)計復(fù)雜的控制程序。一般比較復(fù)雜的程序，都可以分成若干個功能比較簡單的程序段，一個程序段可以看成整個控制過程中的一步。從整個角度去看，一個復(fù)雜系統(tǒng)的控制過程是由這樣若干個步組成的。系統(tǒng)控制的任務(wù)實際上可以認(rèn)為在不同時刻或者在不同進(jìn)程中去完成對各個步的控制。為此，不少 PLC 生產(chǎn)廠家在自己的PLC中增加了步進(jìn)順控指令。在畫完各個步進(jìn)的狀態(tài)流程圖之后，可以利用步進(jìn)順控指令方便地編寫控制程序。

PLC程序的編制方法是什么已經(jīng)介紹完了，現(xiàn)在大家對于PLC控制程序的吧編制都已經(jīng)了解了，在以后編制PLC控制程序的時候可以參考以上的方式來編制。
