描述
可能有人疑慮,PLC編程大部分是步進編程,這一個個標準塊都是針對控制對象的,那控制順序如何實現(xiàn)呢?這就要求編寫專門的順序控制FB塊,或者使用Siemens現(xiàn)成的Graph7來實現(xiàn),這點與一般編程沒什么差別。
結(jié)束語:現(xiàn)在的工業(yè)控制領(lǐng)域有很多程序高手,他們很精通算法,也有著自己的編程理念,當我和一些人探討標準化時,他們認識到標準化的高效性,但認為這樣無法體現(xiàn)自己的編程水準,是的,如上所述作為應(yīng)用層面的程序設(shè)計是不要很高的編程水平,但要想想,一個人難道能一輩子去搞現(xiàn)場調(diào)試嗎?若想體現(xiàn)自己的價值,可以從事標準編程。我更希望他們能花一點時間研究程序架構(gòu),各行各業(yè),真正的大師是系統(tǒng)架構(gòu)設(shè)計者,編程小技巧只不過是為好的架構(gòu)錦上添花。
