采用開放控制的原因一方面是系統(tǒng)功能集成的需要，另一方面也是由于一些工業(yè)用 戶對功能過分苛求所致。如果能夠給予高度的重視，就能夠獲得更多的基本技術(shù)知識。PLC制造商專注于系統(tǒng)功能化，而工業(yè)用戶則專注于系統(tǒng)應(yīng)用。人們可以看到，將來的發(fā)展趨勢是將更多的功能進(jìn)一步集成到一個控制箱內(nèi)。因而像順序控制和過程控制這樣的事件將會采用功能化方式進(jìn)行處理，其他像運(yùn)動控制等也能夠共享到相同的控制結(jié)構(gòu)體系中。

    可以相信，PLC技術(shù)將繼續(xù)向開放式控制系統(tǒng)方向轉(zhuǎn)移，尤其是基于工業(yè)PC的控制系統(tǒng)。后者除了在靈活性方面比傳統(tǒng)PLC具有截然不同的優(yōu)勢外，還具有其他優(yōu)點(diǎn)，如能夠縮短系統(tǒng)投放到市場的周期，降低系統(tǒng)費(fèi)用，提高從工廠底層到企業(yè)辦公自動化的數(shù)據(jù)信息流動效率等。

    關(guān)于工業(yè)PC控制系統(tǒng)的實(shí)時響應(yīng)問題已經(jīng)得到很好的解決，也許其主要的東西仍然隱藏在技術(shù)背后，但缺乏相應(yīng)的跟蹤記錄。對于PLC來講，堅(jiān)固性是其主要特點(diǎn)之一，這已經(jīng)有相當(dāng)多的跟蹤記錄來驗(yàn)證。工業(yè)用戶仍然非常小心地對待PLC，他們正在對PLC作不同的技術(shù)測試工作。在利用一種新技術(shù)時，工業(yè)用戶需要考慮的問題是要冒多大的風(fēng)險，同時需要考慮對其商務(wù)活動能夠帶來多少機(jī)會和收益。
