任何一種控制系統(tǒng)都是為了實(shí)現(xiàn)被控對(duì)象的工藝要求,以提高生產(chǎn)效率和產(chǎn)品質(zhì)量。因此,在設(shè)計(jì)PLC控制系統(tǒng)時(shí),應(yīng)遵循以下基本原則:
1. 大限度地滿足被控對(duì)象的控制要求
充分發(fā)揮PLC的功能,大限度地滿足被控對(duì)象的控制要求,是設(shè)計(jì)PLC控制系統(tǒng)的首要前提,這也是設(shè)計(jì)中重要的一條原則。這就要求設(shè)計(jì)人員在設(shè)計(jì)前就要深入現(xiàn)場(chǎng)進(jìn)行調(diào)查研究,收集控制現(xiàn)場(chǎng)的資料,收集相關(guān)先進(jìn)的國(guó)內(nèi)、國(guó)外資料。同時(shí)要注意和現(xiàn)場(chǎng)的工程管理人員、工程技術(shù)人員、現(xiàn)場(chǎng)操作人員緊密配合,擬定控制方案,共同解決設(shè)計(jì)中的重點(diǎn)問題和疑難問題。
2. 保證PLC控制系統(tǒng)安 全 可 靠
保證PLC控制系統(tǒng)能夠長(zhǎng)期安全、可靠、穩(wěn)定運(yùn)行,是設(shè)計(jì)控制系統(tǒng)的重要原則。這就要求設(shè)計(jì)者在系統(tǒng)設(shè)計(jì)、元器件選擇、軟件編程上要全面考慮,以確保控制系統(tǒng)安 全 可 靠。例如:應(yīng)該保證PLC程序不僅在正常條件下運(yùn)行,而且在非正常情況下(如突然掉電再上電、按鈕按錯(cuò)等),也能正常工作。
