任何一種控制系統(tǒng)都是為了實現(xiàn)被控對象的工藝要求，以提高生產(chǎn)效率和產(chǎn)品質(zhì)量。因此，在設(shè)計PLC控制系統(tǒng)時，應(yīng)遵循以下基本原則：

　　1. 大限度地滿足被控對象的控制要求

　　充分發(fā)揮PLC的功能，大限度地滿足被控對象的控制要求，是設(shè)計PLC控制系統(tǒng)的前提，這也是設(shè)計中重要的一條原則。這就要求設(shè)計人員在設(shè)計前就要深入現(xiàn)場進行調(diào)查研究，收集控制現(xiàn)場的資料，收集相關(guān)先進的國內(nèi)、國外資料。同時要注意和現(xiàn)場的工程管理人員、工程技術(shù)人員、現(xiàn)場操作人員緊密配合，擬定控制方案，共同解決設(shè)計中的重點問題和疑難問題。

　　2. 保證PLC控制系統(tǒng)可靠

　　保證PLC控制系統(tǒng)能夠長期、可靠、穩(wěn)定運行，是設(shè)計控制系統(tǒng)的重要原則。這就要求設(shè)計者在系統(tǒng)設(shè)計、元器件選擇、軟件編程上要考慮，以確保控制系統(tǒng)可靠。例如：應(yīng)該保證PLC程序不僅在正常條件下運行，而且在非正常情況下（如突然掉電再上電、按鈕按錯等），也能正常工作。
