DCS具有以下特點(diǎn)：
(1)高可靠性 由于DCS將系統(tǒng)控制功能分散在各臺(tái)計(jì)算機(jī)上實(shí)現(xiàn)，系統(tǒng)結(jié)構(gòu)采用容錯(cuò)設(shè)計(jì)，因此某一臺(tái)計(jì)算機(jī)出現(xiàn)的故障不會(huì)導(dǎo)致系統(tǒng)其它功能的喪失。此外，由于系統(tǒng)中各臺(tái)計(jì)算機(jī)所承擔(dān)的任務(wù)比較單一，可以針對(duì)需要實(shí)現(xiàn)的功能采用具有特定結(jié)構(gòu)和軟件的專用計(jì)算機(jī)，從而使系統(tǒng)中每臺(tái)計(jì)算機(jī)的可靠性也得到提高。
(2)開(kāi)放性 DCS采用開(kāi)放式、標(biāo)準(zhǔn)化、模塊化和系列化設(shè)計(jì)，系統(tǒng)中各臺(tái)計(jì)算機(jī)采用局域網(wǎng)方式通信，實(shí)現(xiàn)信息傳輸，當(dāng)需要改變或擴(kuò)充系統(tǒng)功能時(shí)，可將新增計(jì)算機(jī)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(jì)算機(jī)的工作。
(3)靈活性 通過(guò)組態(tài)軟件根據(jù)不同的流程應(yīng)用對(duì)象進(jìn)行軟硬件組態(tài)，即確定測(cè)量與控制信號(hào)及相互間連接關(guān)系、從控制算法庫(kù)選擇適用的控制規(guī)律以及從圖形庫(kù)調(diào)用基本圖形組成所需的各種監(jiān)控和報(bào)警畫(huà)面，從而方便地構(gòu)成所需的控制系統(tǒng)。
(4)易于維護(hù) 功能單一的小型或微型專用計(jì)算機(jī)，具有維護(hù)簡(jiǎn)單、方便的特點(diǎn)，當(dāng)某一局部或某個(gè)計(jì)算機(jī)出現(xiàn)故障時(shí)，可以在不影響整個(gè)系統(tǒng)運(yùn)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(guò)通信網(wǎng)絡(luò)傳送各種數(shù)據(jù)，整個(gè)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(shí)現(xiàn)串級(jí)、前饋、解耦、自適應(yīng)和預(yù)測(cè)控制等先進(jìn)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(jì)算機(jī)站、操作員站、工程師站、記錄站、現(xiàn)場(chǎng)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(jì)算機(jī)和可編程控制器構(gòu)成。 處于底層的過(guò)程控制級(jí)一般由分散的現(xiàn)場(chǎng)控制站、數(shù)據(jù)采集站等就地實(shí)現(xiàn)數(shù)據(jù)采集和控制，并通過(guò)數(shù)據(jù)通信網(wǎng)絡(luò)傳送到生產(chǎn)監(jiān)控級(jí)計(jì)算機(jī)。生產(chǎn)監(jiān)控級(jí)對(duì)來(lái)自過(guò)程控制級(jí)的數(shù)據(jù)進(jìn)行集中操作管理，如各種優(yōu)化計(jì)算、統(tǒng)計(jì)報(bào)表、故障診斷、顯示報(bào)警等。隨著計(jì)算機(jī)技術(shù)的發(fā)展，DCS可以按照需要與更高性能的計(jì)算機(jī)設(shè)備通過(guò)網(wǎng)絡(luò)連接來(lái)實(shí)現(xiàn)更的集中管理功能，如計(jì)劃調(diào)度、倉(cāng)儲(chǔ)管理、能源管理等。
