OPC方案

   　 DCS、PLC都具有OPC接口能力，采用OPC技術實現DCS與BOP PLC系統的聯網，其系統結構見圖3。

　　相對于直連方案和Modbus方案，OPC方案具有以下主要特點:

  　  (1)Ovation DCS和BOP PLC系統上位機軟件IFIX均基于(JPC標準開發，且DCS的操作員站和BOP PLC系統上位機均支持以太網通訊，因此易于實現。

   　 (2)DCS數據庫和ROP PLC系統數據庫在DCS中可以整合為一個數據庫，*實現在DCS上對BOP的監控。

   　 (3)采用快速光纖以太網可保證網絡的暢通和整個系統的性能，且網絡拓撲結構簡單，需要額外增加的設備較少。

   　 (4)當BOPPLC系統發生雙機熱備切換時，DCS和PLC系統的通訊仍然能夠正常進行，無需專門設計切換電路。
