從可靠性來(lái)說(shuō)，IPC要比單片機(jī)要好得多，但其價(jià)格昂貴，
不計(jì)其整機(jī)價(jià)格，單就要滿足I/O點(diǎn)數(shù)據(jù)的板卡量（32通道，約10塊）費(fèi)用就不少，其價(jià)格要遠(yuǎn)遠(yuǎn)高于采用PLC控制的價(jià)格。
更為重要的是工控機(jī)更新?lián)Q代較快，不但硬件如此，而且最根本的操作系統(tǒng)也不斷地更新?lián)Q代，換句話說(shuō)，如果設(shè)備控制系統(tǒng)出現(xiàn)故障，更換硬件，可能意味著更新操作系統(tǒng)，進(jìn)而導(dǎo)致整個(gè)系統(tǒng)的應(yīng)用軟件（包括界面）都要重新設(shè)計(jì)（或開(kāi)發(fā)），這對(duì)太多數(shù)用戶來(lái)說(shuō)是不能接受的。
所以，本人認(rèn)為此方案也不適用。
3 PLC控制
· 可靠性
自第一臺(tái)PLC誕生就是應(yīng)用于工業(yè)現(xiàn)場(chǎng)控制，不可否認(rèn)，PLC的
可靠性得到了工控業(yè)界的認(rèn)可。據(jù)最近行業(yè)統(tǒng)計(jì)顯示，目前采用PLC控制的設(shè)備份額達(dá)90％。
· 成本低
就此設(shè)備的控制來(lái)說(shuō)，采用PLC來(lái)進(jìn)行的設(shè)備開(kāi)發(fā)和控制費(fèi)用
都要遠(yuǎn)遠(yuǎn)低于采用單片機(jī)或IPC的費(fèi)用，其系統(tǒng)可大可小，小的幾點(diǎn)，大的數(shù)千點(diǎn)，甚至上萬(wàn)點(diǎn)，很好解決工業(yè)控制問(wèn)題，適用于很多場(chǎng)合。
· 開(kāi)發(fā)周期短
采用PLC進(jìn)行設(shè)備控制，工程師無(wú)須花太多的精力在硬件的處理上，采用積木式結(jié)構(gòu)很快可以形成系統(tǒng)電路，大部分精力集中在工藝的了解處理和程序的編寫上，有利于設(shè)備的快速開(kāi)發(fā)，程序的編輯、修改和調(diào)試也都可隨時(shí)進(jìn)行，縮短了開(kāi)發(fā)時(shí)間。
