順序功能圖（SFC）
順序功能圖，亦稱功能流程圖或狀態(tài)轉(zhuǎn)移圖，是一種圖形化的功能性說明語言，于描述工業(yè)順序控制程序，也是IEC61131-3的標(biāo)準(zhǔn)編程語言。使用它可以對具有并發(fā)、選擇等復(fù)雜結(jié)構(gòu)的系統(tǒng)進(jìn)行編程，一些高檔的PLC提供了用于SFC編程的指令，但一些低檔的PLC并不支持SFC編程語言。順序功能圖示例如圖3所示。
順序功能圖主要由“狀態(tài)"和“轉(zhuǎn)移"等基本元素組成。通過這些基本元素的不同組合，可以表達(dá)各種各樣的復(fù)雜順序控制邏輯，控制規(guī)律的表達(dá)簡潔明了。
