1. 最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，最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)中最重要的一條原則。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(wèn)題和疑難問(wèn)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?？刂葡到y(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。
