PLC梯形圖編程的幾個步驟
（一）決定系統所需的動作及次序。
當使用可編程控制器時，最重要的一環是決定系統所需的輸入及輸出。輸入及輸出要求：
(1) 第一步是設定系統輸入及輸出數目。
(2) 第二步是決定控制先后、各器件相應關系以及作出何種反應。
（二）對輸入及輸出器件編號
每一輸入和輸出，包括定時器、計數器、內置寄存器等都有一個唯一的對應編號，不能混用。
（三）畫出梯形圖。
根據控制系統的動作要求，畫出梯形圖。
梯形圖設計規則
（1）觸點應畫在水平線上，并且根據自左至右、自上而下的原則和對輸出線圈的控制路徑來畫。
（2）不包含觸點的分支應放在垂直方向，以便于識別觸點的組合和對輸出線圈的控制路徑。
（3）在有幾個串聯回路相并聯時，應將觸頭多的那個串聯回路放在梯形圖的最上面。在有幾個并聯回路相串聯時，應將觸點最多的并聯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。
（4）不能將觸點畫在線圈的右邊。
（四）將梯形圖轉化為程序
把繼電器梯形圖轉變為可編程控制器的編碼，當完成梯形圖以后，下一步是把它的編碼編譯成可編程控制器能識別的程序。
這種程序語言是由序號（即地址）、指令（控制語句）、器件號（即數據）組成。地址是控制語句及數據所存儲或擺放的位置，指令告訴可編程控制器怎樣利用器件作出相應的動作。
（五）在編程方式下用鍵盤輸入程序。
（六）編程及設計控制程序。
（七）測試控制程序的錯誤并修改。
（八）保存完整的控制程序。ALLEN-BRADLEY 1771-OZL CONTACT OUTPUT MODULE with 1771-WD SER A REV D02 (2A1)
