力求簡單、經(jīng)濟、使用及維修方便
? 一個新的控制工程固然能提高產(chǎn)品的質(zhì)量和數(shù)量,帶來巨大的經(jīng)濟效益和社會效益,但新工程的投入、技術(shù)的培訓(xùn)、設(shè)備的維護也將導(dǎo)致運行資金的增加。因此,在滿足控制要求的前提下,一方面要注意不斷地擴大工程的效益,另一方面也要注意不斷地降低工程的成本。這就要求設(shè)計者不僅應(yīng)該使控制系統(tǒng)簡單、經(jīng)濟,而且要使控制系統(tǒng)的使用和維護方便、成本低,不宜盲目追求自動化和高指標
適應(yīng)發(fā)展的需要
?由于技術(shù)的不斷發(fā)展,控制系統(tǒng)的要求也將會不斷地提高,設(shè)計時要適當考慮到今后控制系統(tǒng)發(fā)展和完善的需要。這就要求在選擇PLC、輸入/輸出模塊、I/O點數(shù)和內(nèi)存容量時,要適當留有裕量,以滿足今后生產(chǎn)的發(fā)展和工藝的改進。
