可編程控制器PLC系統程序、用戶程序、編程語言

1、系統程序

系統程序是PLC賴以工作的基礎，采用匯編語言編寫，在PLC出廠時就已固化于ROM型系統程序存儲器中。

系統程序分為系統監控程序和解釋程序。

系統監控程序用于監視并控制PLC的工作，如診斷PLC系統工作是否正常，對PLC各模塊的工作進行控制，與處設交換信息，根據用戶的設定使PLC比處在編制用戶程序狀態或者處在運行用戶程序狀態等。

解釋程序用于把用戶程序解釋成微處理器能夠執行的程序。來自PLC之家。 

2、用戶程序

用戶程序又稱為應用程序，是用戶為完成某一特定   的控制任務而利用PLC的編程語言編制的程序。 來自PLC之家。 

用戶程序通過編程器輸入到PLC的用戶程序存儲器中。 

3、編程語言

可編程控制器是通過程序對系統進行控制的，所以各種機型的PLC都有自己的編程語言。www.plc100。。ｃｏｍ

PLC的編程語言有多種，如梯形圖、語句表、邏輯功能圖、邏輯方程式等。下面介紹常用的梯形圖和語句表編程語言。
