將所有與PLC相關的輸入信號(按鈕、行程開關、速度及溫度等傳感器)，輸出信號(接觸器、電磁閥、信號燈等)分別列表，并按PLC內部接口范圍，給每個信號分配一個確定的編號。
(3)詳細了解生產工藝和設備對控制系統的要求。畫出系統各個功能過程的工作循環圖或流程圖、功能圖及有關信號的時序圖。
(4)按照PLC程序語言的要求設計梯形圖或編寫程序清單。梯形圖上的文字符號應按現場信號與PLC內部接口對照表的規定標注。
2．PLC程序設計的一般原則
(1)保證人身與設備安全的設計都不是多余的。
(2)PLC程序的安全設計，并不代表硬件的安全保護可以省略。
(3)了解PLC自身的特點。
(4)設計調試點易于調試。
