這是一種模仿繼電器控制系統(tǒng)的編程方法。其圖形甚至元件名稱都與繼電器控制電路十分相近。這種方法很容易地就可以把原繼電器控制電路移植成 PLC 的梯形圖語言。這對(duì)于熟悉繼電器控制的人來說，是 方便的一種編程方法。 PLC的指令繁多，但主要的有這么幾種類型： 基本邏輯指令，用于處理邏輯關(guān)系，以實(shí)現(xiàn)邏輯控制。這類指令不管什么樣的PLC都總是有的。 數(shù)據(jù)處理指令，用于處理數(shù)據(jù)，如譯碼，編碼，傳送、移位等等。 數(shù)據(jù)運(yùn)算指令，用于進(jìn)數(shù)據(jù)的運(yùn)算，如十、一、X、/等，可進(jìn)行整形數(shù)計(jì)算，有的還可浮點(diǎn)數(shù)運(yùn)算；也可進(jìn)行邏輯量運(yùn)算，等等。 流程控制指令，用以控制程序運(yùn)行流程。PLC的用戶程序一般是從零地址的指令開始執(zhí)行，按順序推進(jìn)。但遇到流程控制指令也可作相應(yīng)改變。流程控制指令也較多，運(yùn)用得好，可使程序簡(jiǎn)練，并便于調(diào)試與閱讀。 狀態(tài)監(jiān)控指令，用以監(jiān)視及記錄PLC及其控制系統(tǒng)的工作狀態(tài)，對(duì)PLC控制系統(tǒng)的工作可靠性大有幫助。 當(dāng)然，并不是所有的PLC都有上述那么多類的指令，也不是有的PLC僅有上述幾類指令。以上只是指出幾個(gè)例子，說明要從哪幾個(gè)方面了解PLC指令，從中也可大致看出指令的多少及功能將怎樣影響PLC的性能。 除了指令，為進(jìn)行通訊，PLC還有相應(yīng)的協(xié)議與通訊指令或命令，這些也反映了PLC的性能。 6支持軟件 為了便于編制PLC程序
