隨著可編程控制器的發展，其編程軟件呈現多樣化和化發展趨勢。由于可編程控制器類型較多，各個不同機型對應編程軟件也是有一定的差別，特別是各個生產廠家的可編程控制器之間，它們的編程軟件不能通用，但是同一生產廠家生產的可編程控制器一般都可以使用。這一點請讀者注意的。
二、編程軟件編程語言表達方式
可編程控制器與一般的計算機相類似，在軟件方面有系統軟件和應用軟件之分，只是可編程控制器的系統軟件由可編程控制器生產廠家固化在 ROM 中，一般的用戶只能在應用軟件上進行操作，即通過編程軟件來編制用戶程序。編程軟件是由可編程控制器生產廠家提供的編程語言，至今為止還沒有一種能適合各種可編程控制器的通用的編程語言，但是各個可編程控制器發展過程有類似之處，可編程控制器的編程語言即編程工具都大體差不多，一般有如下五種表達方式。MEASUREX 08562100
( 一 ) 梯形圖（ Ladder Diagram ）
梯形圖是一種以圖形符號及圖形符號在圖中的相互關系表示控制關系的編程語言，它是從繼電器控制電路圖演變過來的。梯形圖將繼電器控制電路圖進行簡化，同時加進了許多功能強大、使用靈活的指令，將微機的特點結合進去，使編程更加容易，而實現的功能卻大大超過傳統繼電器控制電路圖，是目前*普通的一種可編程控制器編程語言。
  化整為零、順藤摸瓜、先主后輔、集零為整、安全保護、全面檢查。
采用化整為零的原則以某一電動機或電器元件（如接觸器或繼電器線圈）為對象，從電源開始，自上而下，自左而右，逐一分析其接通斷開關系。
2．分析方法與步驟
①分析主電路MEASUREX 08562100
無論線路設計還是線路分析都是先從主電路入手。主電路的作用是保證機床拖動要求的實現。從主電路的構成可分析出電動機或執行電器的類型、工作方式，起動、轉向、調速、制動等控制要求與保護要求等內容。
②分析控制電路
主電路各控制要求是由控制電路來實現的，運用“化整為零”、“順藤摸瓜”的原則，將控制電路按功能劃分為若干個局部控制線路，從電源和主令信號開始，經過邏輯判斷，寫出控制流程，以簡便明了的方式表達出電路的自動工作過程。
