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行處理，其他像運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，如能夠縮短系統(tǒng)投放到市場的周期，降低系統(tǒng)費用，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，堅固性是其主要特點之一，這已經(jīng)有相當(dāng)多的跟蹤記錄來驗證。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會和收益。
