分散控制系統網絡體系結構
工廠級(上層、管理層)包括工廠信息管理和生產管理，負責與工廠管理計算機的連接，計算機間的管理數據交換通過工廠主干網實現。主干網采用ISO／OSI-MAP／TOP或TCP／IP-Ethernet網絡協議標準。隨著工廠自動化規模的不斷擴大，這一級的功能也越來越強，它是DCS 向CIPS 發展的一個重要標志。
車間級(中層、監控層)包括過程控制和過程管理，用于控制室、現場控制設備和各現場控制裝置間的連接。通信網采用中速、載帶工業過程數據公路的形式(ProwayC或IEEE802.4)。這是DCS的實時工業控制網絡，應具有高可靠性、高使用性、實時性強、有自診斷功能、有自組態功能、容易接入新站等。
現場級(低層)用于連接過程控制中的傳感器、執行器、智能儀表等。現場以標準的現場總線為發展目標，現已有了兩個國際組織的現場總線產品，現場總線將是DCS 發展的一個重要方向。
2 現場總線
2.1 現場總線標準
現場總線標準的部分被命名為H1，定義了一個低速、帶電鏈路的數字信號取代4～20 mA模擬量傳輸信號。當H1被采用后，智能傳感器將能夠與數字控制系統直接通信。第二部分H2，定義了一個高速、不帶電的鏈路，使協議可應用于邏輯和控制。H2協議的通信速率為1 Mb，而H1通信速率為31.25 Kb。
