DCS具有以下特點：
(1)高可靠性 由于DCS將系統(tǒng)控制功能分散在各臺計算機上實現(xiàn)，系統(tǒng)結(jié)構(gòu)采用容錯設(shè)計，因此某一臺計算機出現(xiàn)的故障不會導(dǎo)致系統(tǒng)其它功能的喪失。此外，由于系統(tǒng)中各臺計算機所承擔的任務(wù)比較單一，可以針對需要實現(xiàn)的功能采用具有特定結(jié)構(gòu)和軟件的專用計算機，從而使系統(tǒng)中每臺計算機的可靠性也得到提高。
(2)開放性 DCS采用開放式、標準化、模塊化和系列化設(shè)計，系統(tǒng)中各臺計算機采用局域網(wǎng)方式通信，實現(xiàn)信息傳輸，當需要改變或擴充系統(tǒng)功能時，可將新增計算機方便地連入系統(tǒng)通信網(wǎng)絡(luò)或從網(wǎng)絡(luò)中卸下，幾乎不影響系統(tǒng)其他計算機的工作。
(3)靈活性 通過組態(tài)軟件根據(jù)不同的流程應(yīng)用對象進行軟硬件組態(tài)，即確定測量與控制信號及相互間連接關(guān)系、從控制算法庫選擇適用的控制規(guī)律以及從圖形庫調(diào)用基本圖形組成所需的各種監(jiān)控和報警畫面，從而方便地構(gòu)成所需的控制系統(tǒng)。
(4)易于維護 功能單一的小型或微型專用計算機，具有維護簡單、方便的特點，當某一局部或某個計算機出現(xiàn)故障時，可以在不影響整個系統(tǒng)運行的情況下在線更換，迅速排除故障。
(5)協(xié)調(diào)性 各工作站之間通過通信網(wǎng)絡(luò)傳送各種數(shù)據(jù)，整個系統(tǒng)信息共享，協(xié)調(diào)工作，以完成控制系統(tǒng)的總體功能和優(yōu)化處理。
(6)控制功能齊全 控制算法豐富，集連續(xù)控制、順序控制和批處理控制于一體，可實現(xiàn)串級、前饋、解耦、自適應(yīng)和預(yù)測控制等先進控制，并可方便地加入所需的特殊控制算法。 DCS的構(gòu)成方式十分靈活，可由專用的管理計算機站、操作員站、工程師站、記錄站、現(xiàn)場控制站和數(shù)據(jù)采集站等組成，也可由通用的服務(wù)器、工業(yè)控制計算機和可編程控制器構(gòu)成。 處于底層的過程控制級一般由分散的現(xiàn)場控制站、數(shù)據(jù)采集站等就地實現(xiàn)數(shù)據(jù)采集和控制，并通過數(shù)據(jù)通信網(wǎng)絡(luò)傳送到生產(chǎn)監(jiān)控級計算機。生產(chǎn)監(jiān)控級對來自過程控制級的數(shù)據(jù)進行集中操作管理，如各種優(yōu)化計算、統(tǒng)計報表、故障診斷、顯示報警等。隨著計算機技術(shù)的發(fā)展，DCS可以按照需要與更高性能的計算機設(shè)備通過網(wǎng)絡(luò)連接來實現(xiàn)更的集中管理功能，如計劃調(diào)度、倉儲管理、能源管理等。
