PLC梯形圖編程的幾個(gè)步驟
（一）決定系統(tǒng)所需的動(dòng)作及次序。
當(dāng)使用可編程控制器時(shí)，最重要的一環(huán)是決定系統(tǒng)所需的輸入及輸出。輸入及輸出要求：
(1) 第一步是設(shè)定系統(tǒng)輸入及輸出數(shù)目。
(2) 第二步是決定控制先后、各器件相應(yīng)關(guān)系以及作出何種反應(yīng)。
（二）對(duì)輸入及輸出器件編號(hào)
每一輸入和輸出，包括定時(shí)器、計(jì)數(shù)器、內(nèi)置寄存器等都有一個(gè)唯一的對(duì)應(yīng)編號(hào)，不能混用。
（三）畫(huà)出梯形圖。
根據(jù)控制系統(tǒng)的動(dòng)作要求，畫(huà)出梯形圖。
梯形圖設(shè)計(jì)規(guī)則
（1）觸點(diǎn)應(yīng)畫(huà)在水平線(xiàn)上，并且根據(jù)自左至右、自上而下的原則和對(duì)輸出線(xiàn)圈的控制路徑來(lái)畫(huà)。
（2）不包含觸點(diǎn)的分支應(yīng)放在垂直方向，以便于識(shí)別觸點(diǎn)的組合和對(duì)輸出線(xiàn)圈的控制路徑。
（3）在有幾個(gè)串聯(lián)回路相并聯(lián)時(shí)，應(yīng)將觸頭多的那個(gè)串聯(lián)回路放在梯形圖的最上面。在有幾個(gè)并聯(lián)回路相串聯(lián)時(shí)，應(yīng)將觸點(diǎn)最多的并聯(lián)回路放在梯形圖的最左面。這種安排，所編制的程序簡(jiǎn)潔明了，語(yǔ)句較少。
（4）不能將觸點(diǎn)畫(huà)在線(xiàn)圈的右邊。
（四）將梯形圖轉(zhuǎn)化為程序
把繼電器梯形圖轉(zhuǎn)變?yōu)榭删幊炭刂破鞯木幋a，當(dāng)完成梯形圖以后，下一步是把它的編碼編譯成可編程控制器能識(shí)別的程序。
這種程序語(yǔ)言是由序號(hào)（即地址）、指令（控制語(yǔ)句）、器件號(hào)（即數(shù)據(jù)）組成。地址是控制語(yǔ)句及數(shù)據(jù)所存儲(chǔ)或擺放的位置，指令告訴可編程控制器怎樣利用器件作出相應(yīng)的動(dòng)作。
（五）在編程方式下用鍵盤(pán)輸入程序。
（六）編程及設(shè)計(jì)控制程序。
（七）測(cè)試控制程序的錯(cuò)誤并修改。
（八）保存完整的控制程序。Allen Bradley 1492-N4 - Marking Strip - (3 rolls of 25')
