從影響成本的各個因素綜合考慮　從目前生產設備控制裝置來說，有三種類型：①繼電器控制。②半導體器件控制。③PLC控制。
價格僅是選擇PLC品牌的一個因素，而可靠性是選擇時需要考慮的又一個因素。
從設計、生產周期長短考慮　不論是老設備改造，還是設計新的生產機械設備，毫無疑問，生產、設計周期越短越好，甚至希望邊設計、邊安裝、邊調試和邊生產，特別是產品更新?lián)Q代，生產工藝改造，不需改動現(xiàn)有生產設備及其外部接線，就能馬上組織生產，這不僅節(jié)約了勞動力，而且新產品能盡快投入市場。這無疑給企業(yè)增加了活力，提高了經濟效益。如果把這些要求得以實現(xiàn)，繼電器或半導體都不能滿足，而PLC則完全可以實現(xiàn)。這是因為若用PLC不必改動外部設備接線，只要在軟件上作文章就可以了。也就是說只要改變梯形圖，按照新工藝要求重新輸入新程序或修改原程序即可。這既經濟又簡捷，可以達到事半功倍的目的。
眾所周知，目前我國75%的生產機械設備，都是采用繼電器控制，除了可靠性差外，設計程序也很繁雜。從方案的確立到技術條件的設計以及施工的設計，圖面的工作量很大，這勢必造成設計周期長。而采用PLC控制可以大大縮短設計周期，甚至有些文件資料也不必繪制成圖。設計人員完全可以利用編程器上屏幕顯示來輸入，或修改程序使得梯形圖能準確無誤地反映生產要求。編程人員也可根據(jù)新產品對生產提出的新工藝要求，重新編寫程序并把它存儲在EEPROM模塊中去，需要加工哪個產品的程序，操作人員可以隨時調用，這既方便、簡單又可保密。開發(fā)這種軟件對優(yōu)化生產過程，提高產品數(shù)量和質量，提高勞動生產率，非常具有實際意義。僅此一點也深受生產及設計者的歡迎。
