(3) 時(shí)序流程圖法：時(shí)序流程圖法使首先畫出控制系統(tǒng)的時(shí)序圖（即到某一個(gè)時(shí)間應(yīng)該進(jìn)行哪項(xiàng)控制的控制時(shí)序圖），再根據(jù)時(shí)序關(guān)系畫出對(duì)應(yīng)的控制任務(wù)的程序框圖，zui后把程序框圖寫成 PLC 程序。時(shí)序流程圖法很適合于以時(shí)間為基準(zhǔn)的控制系統(tǒng)的編程方法。

(4) 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(jì)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(gè)功能比較簡(jiǎn)單的程序段，一個(gè)程序段可以看成整個(gè)控制過(guò)程中的一步。從整個(gè)角度去看，一個(gè)復(fù)雜系統(tǒng)的控制過(guò)程是由這樣若干個(gè)步組成的。系統(tǒng)控制的任務(wù)實(shí)際上可以認(rèn)為在不同時(shí)刻或者在不同進(jìn)程中去完成對(duì)各個(gè)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(gè)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。

2. 經(jīng)驗(yàn)法編程

經(jīng)驗(yàn)法是運(yùn)用自己的或別人的經(jīng)驗(yàn)進(jìn)行設(shè)計(jì)。多數(shù)是設(shè)計(jì)前先選擇與自己工藝要求相近的程序，把這些程序看成是自己的“試驗(yàn)程序"。結(jié)合自己工程的情況，對(duì)這些“試驗(yàn)程序"逐一修改，使之適合自己的工程要求。這里所說(shuō)的經(jīng)驗(yàn)，有的是來(lái)自自己的經(jīng)驗(yàn)總結(jié)，有的可能是別人的設(shè)計(jì)經(jīng)驗(yàn)，就需要日積月累，善于總結(jié)。

3. 計(jì)算機(jī)輔助設(shè)計(jì)編程

計(jì)算機(jī)輔助設(shè)計(jì)是通過(guò) PLC 編程軟件在計(jì)算機(jī)上進(jìn)行程序設(shè)計(jì)、離線或在線編程、離線仿真和在線調(diào)試等等。使用編程軟件可以十分方便地在計(jì)算機(jī)上離線或在線編程、在線調(diào)試，使用編程軟件可以十分方便地在計(jì)算機(jī)上進(jìn)行程序的存取、加密以及形成 EXE 運(yùn)行文件。

7.3.2 PLC 軟件系統(tǒng)設(shè)計(jì)的步驟

在了解了程序結(jié)構(gòu)和編程方法的基礎(chǔ)上，就要實(shí)際地編寫 PLC 程序了。編寫 PLC 程序和編寫其他計(jì)算機(jī)程序一樣，都需要經(jīng)歷如下過(guò)程。

1. 對(duì)系統(tǒng)任務(wù)分塊

分塊的目的就是把一個(gè)復(fù)雜的工程，分解成多個(gè)比較簡(jiǎn)單的小任務(wù)。這樣就把一個(gè)復(fù)雜的大問(wèn)題化為多個(gè)簡(jiǎn)單的小問(wèn)題。這樣可便于編制程序。

2. 編制控制系統(tǒng)的邏輯關(guān)系圖

從邏輯關(guān)系圖上，可以反應(yīng)出某一邏輯關(guān)系的結(jié)果是什么，這一結(jié)果又英國(guó)導(dǎo)出哪些動(dòng)作。這個(gè)邏輯關(guān)系可以是以各個(gè)控制活動(dòng)順序?yàn)榛鶞?zhǔn)，也可能是以整個(gè)活動(dòng)的時(shí)間節(jié)拍為基準(zhǔn)。邏輯關(guān)系圖反映了控制過(guò)程中控制作用與被控對(duì)象的活動(dòng)，也反應(yīng)了輸入與輸出的關(guān)系。
