梯形圖是PLC控制系統(tǒng)中使用得最多的圖形編程語言，被稱為PLC的{dy}編程語言。梯形圖與電器控制系統(tǒng)的電路圖很相似，具有直觀易懂的優(yōu)點(diǎn)，很容易被工廠電氣人員掌握，特別適用于開關(guān)量邏輯控制。梯形圖常被稱為電路或程序，梯形圖的設(shè)計(jì)稱為編程。PLC梯形圖設(shè)計(jì)規(guī)則（或規(guī)范）如下：
(1)觸點(diǎn)應(yīng)畫在水平線上，不能畫在垂直分支上。應(yīng)根據(jù)自左至右、自上而下的原則和對(duì)輸出線圈的幾種可能控制路徑來畫。
(2)不包含觸點(diǎn)的分支應(yīng)放在垂直方向，不可放在水平位置，以便于識(shí)別觸點(diǎn)的組合和對(duì)輸出線圈的控制路徑。
(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，所編制的程序簡潔明了，語句較少。
(3)不能將觸點(diǎn)畫在線圈的右邊，只能在觸點(diǎn)的右邊接線圈。
