工控zui重要的*是穩(wěn)定,第二是穩(wěn)定,第三還是穩(wěn)定,而穩(wěn)定不單是硬件方面,軟件其實也非常重要,再有就是抗于擾。這里只談PLC軟件。 我把PLC程序規(guī)范為以下幾個組成部分： 
一、系統(tǒng)初始化， 
二、過程或狀態(tài)的描述(相當于繼電、接觸控制中的中間繼電器)， 
三、人機操作控制(手動操作，參數(shù)修改等)， 
四、設備控制輸出(電機、閥等)， 
五、通信(各控制設備間的互鎖和數(shù)據(jù)交換)、 
六、過程或狀態(tài)的故障描述， 
七、報警輸出和故障位置等信息顯示， 
八、生產(chǎn)過程報表(產(chǎn)、質(zhì)量等)。

下面主要談談過程或狀態(tài)的描述和設備控制輸出，因為這基本上是程序的主要部分。
程序好壞的標準：穩(wěn)定、易調(diào)試、易修改、易擴展、易讀、實時性(快)。在這么多年的實踐中，我感到先由過程或狀態(tài)的描述得到各種狀態(tài)變量，再對設備輸出進行編程能比較好的達到上述目標，可能它在快的方面有所欠缺(因為程序長一些)但這*可以從其它方面得到解決(例如中斷)。這種想法主要源自數(shù)學上的狀態(tài)方程：Q=f(S1，S2，S3……..,Sn)其中Q為設備輸出,S1、S2、S3…….Sn為狀態(tài)變量(包括輸入輸出)。f是由指令系統(tǒng)組成的算法。
