8經(jīng)濟指標

以上七條講的都是PLC的技術(shù)性能。其實，使用PLC，還要考慮經(jīng)濟指標。經(jīng)濟是基礎(chǔ)，經(jīng)濟上不合算，不能帶來經(jīng)濟效益，使用PLC也就沒有基礎(chǔ)。所以，這個指標也是重要的。經(jīng)濟指標最簡單的就是看價格。一般講，同樣技術(shù)性能的PLC，價格低其經(jīng)濟指標就好

此外，還要看供貨情況，供貨不及時，影響使用，價格即使低，也不一定就好；看技術(shù)服務(wù)，資料不全，用戶出現(xiàn)問題得不到技術(shù)支持也不好。

對經(jīng)濟指標還要作綜合分析，要看使用了PLC能否帶來效益，然后，再分析使用哪家的PLC效益更好些
