編程指令：指令是PLC被告知要做什么，以及怎樣去做的代碼或符號。從本質(zhì)上講，指令只是一些二進制代碼，這點PLC與普通的計算機是完全相同的。同時PLC也有編譯系統(tǒng)，它可以把一些文字符號或圖形符號編譯成機器碼，所以用戶看到的PLC指令一般不是機器碼而是文字代碼，或圖形符號。常用的助記符語句用英文文字（可用多國文字）的縮寫及數(shù)字代表各相應指令。常用的圖形符號即梯形圖，它類似于電氣原理圖是符號，易為電氣工作人員所接受。? 指令系統(tǒng)：一個PLC所具有的指令的全體稱為該PLC的指令系統(tǒng)。它包含著指令的多少，各指令都能干什么事，代表著PLC的功能和性能。一般講，功能強、性能好的PLC，其指令系統(tǒng)必然豐富，所能干的事也就多。我們在編程之前必須弄清PLC的指令系統(tǒng)? 、。

嵌入式PLC的發(fā)展也呈現(xiàn)多元化，國內(nèi)外均有良好表現(xiàn)：德國赫優(yōu)訊推出的將現(xiàn)場總線技術(shù)和PLC技術(shù)結(jié)合的netPLC很有特色;國內(nèi)幾年前就有華中科技大學在EASYCORE1.00核心芯片組中加載了嵌入式PLC系統(tǒng)軟件，作為硬件平臺，開發(fā)了多模人通道的嵌入式PLC;還有一種發(fā)展路徑是以開發(fā)PLC與人機界面相結(jié)合的硬件/軟件一體化為目標的平臺，充分利用了CASE工具，結(jié)合各類嵌入式芯片的開發(fā)平臺和各種輸入/輸出通道的硬件電路庫，專為機電設備開發(fā)客制化、具有ODM性質(zhì)的專用PLC。
