描述
④編程軟件的多樣化和高級化、標準化:采用多種編程語言,有面向順序控制的步進順序語言和面向過程控制系統(tǒng)的流程圖語言,后者是一種面向功能塊的語言,能夠表示過程中動態(tài)變量與信號的相互聯(lián)結;還有與計算機兼容的高級語言,如BASIC、C及匯編語言;另外還有專用的高級語言,例如三菱的MELSAP采用編譯的方法將語句變?yōu)樘菪螆D程序;也有采用布爾邏輯語言的,CPU能直接執(zhí)行AND、OR、XOR、NOT操作,這種語言執(zhí)行速度很快,但不很直觀。PLC也將具有數(shù)據(jù)庫,并可實現(xiàn)整個網(wǎng)絡的數(shù)據(jù)庫共享,還將不斷發(fā)展自適應控制和專家系統(tǒng)。
⑤構成形式的分散化和集散化:PLC與I/O口分散,分散的每個I/O口輸入輸出點數(shù)可以少到十幾個點,分散的單元可以是幾十個或上百個,通信和網(wǎng)絡功能逐步增強。作為CIMS、CIPS的分支不斷發(fā)展,PLC本身也可分散,分散的PLC與上位機結合構成集散系統(tǒng),分散地進行控制,這就便于構成多層分布式控制,以實現(xiàn)整個工廠或企業(yè)的自動化控制和管理。不同機型的PLC之間、PLC與計算機之間可方便地聯(lián)網(wǎng),實現(xiàn)資源共享,加上功能強大的網(wǎng)絡監(jiān)控軟件,就構成大型PLC控制網(wǎng)絡系統(tǒng)。
