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(shí)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(gè)組成部分： 
一、系統(tǒng)初始化， 
二、過(guò)程或狀態(tài)的描述(相當(dāng)于繼電、接觸控制中的中間繼電器)， 
三、人機(jī)操作控制(手動(dòng)操作，參數(shù)修改等)， 
四、設(shè)備控制輸出(電機(jī)、閥等)， 
五、通信(各控制設(shè)備間的互鎖和數(shù)據(jù)交換)、 
六、過(guò)程或狀態(tài)的故障描述， 
七、報(bào)警輸出和故障位置等信息顯示， 
八、生產(chǎn)過(guò)程報(bào)表(產(chǎn)、質(zhì)量等)。

下面主要談?wù)勥^(guò)程或狀態(tài)的描述和設(shè)備控制輸出，因?yàn)檫@基本上是程序的主要部分。
程序好壞的標(biāo)準(zhǔn)：穩(wěn)定、易調(diào)試、易修改、易擴(kuò)展、易讀、實(shí)時(shí)性(快)。在這么多年的實(shí)踐中，我感到先由過(guò)程或狀態(tài)的描述得到各種狀態(tài)變量，再對(duì)設(shè)備輸出進(jìn)行編程能比較好的達(dá)到上述目標(biāo)，可能它在快的方面有所欠缺(因?yàn)槌绦蜷L(zhǎng)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(xué)上的狀態(tài)方程：Q=f(S1，S2，S3……..,Sn)其中Q為設(shè)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。
