梯形圖的設(shè)計(jì)應(yīng)注意以下三點(diǎn)：

（一）梯形圖按從左到右、從上到下的順序排列。每一邏輯行起始于左母線，然后是觸點(diǎn)的串、并聯(lián)接，zui后是線圈與右母線相聯(lián)。

（二）梯形圖中每個(gè)梯級(jí)流過的不是物理電流，而是“概念電流"，從左流向右，其兩端沒有電源。這個(gè)“概念電流"只是形象地描述用戶程序執(zhí)行中應(yīng)滿足線圈接通的條件。

（三）輸入繼電器用于接收外部輸入信號(hào)，而不能由PLC內(nèi)部其它繼電器的觸點(diǎn)來驅(qū)動(dòng)。因此，梯形圖中只出現(xiàn)輸入繼電器的觸點(diǎn)，而不出現(xiàn)其線圈。輸出繼電器輸出程序執(zhí)行結(jié)果給外部輸出設(shè)備，當(dāng)梯形圖中的輸出繼電器線圈得電時(shí)，就有信號(hào)輸出，但不是直接驅(qū)動(dòng)輸出設(shè)備，而要通過輸出接口的繼電器、晶體管或晶閘管才能實(shí)現(xiàn)。輸出繼電器的觸點(diǎn)可供內(nèi)部編程使用。

在PLC發(fā)展的初期，沿用了設(shè)計(jì)繼電器電路圖的方法來設(shè)計(jì)梯形圖程序，即在已有的些典型梯形圖的基礎(chǔ)上，根據(jù)被控對象對控制的要求，不斷地修改和完善梯形圖。有時(shí)需要多次反復(fù)地調(diào)試和修改梯形圖，不斷地增加中間編程元件和觸點(diǎn)，zui后才能得到一個(gè)較為滿意的結(jié)果。這種方法沒有普遍的規(guī)律可以遵循，設(shè)計(jì)所用的時(shí)間、設(shè)計(jì)的質(zhì)量與編程者的經(jīng)驗(yàn)有很大的關(guān)系，所以有人把這種設(shè)計(jì)方法稱為經(jīng)驗(yàn)設(shè)計(jì)法。它可以用于邏輯關(guān)系較簡單的梯形圖程序設(shè)計(jì)。
