什么是DCS的開放性？
DCS的開放性是指DCS能通過不同的接口方便地與第三方系統或設備連接，并獲取其信息的性能。這種連接主要是通過網絡實現的，采用通用的、開放的網絡協議和標準的軟件接口是DCS開放性的保障。我公司目前采用的DCS系統有很好的開放性。
19、什么是系統冗余？
在一些對系統可靠性要求很高的應用中，DCS的設計需要考慮熱備份也就是系統冗余，這是指系統中一些關鍵模塊或網絡在設計上有一個或多個備份，當現在工作的部分出現問題時，系統可以通過特殊的軟件或硬件自動切換到備份上，從而保證了系統不間斷工作。通常設計的冗余方式包括：CPU冗余、網絡冗余、電源冗余。在極端情況下，一些系統會考慮全系統冗余，即還包括I/O冗余。
