4、儀表系統調試程序
圖1為儀表系統調試程序方框圖。本著分層隔離、平行作業的方法，昌暉儀表將DCS系統調試分劃為經下四個層次：

①第一層次：DCS及輔助儀表盤儀表調試
在這一層次中，通過設置斷點，使DCS調試與輔助儀表盤儀表調試相對獨立、互不干擾，從而便于實現對這兩個工序的平行作業，并可避免因設備狀態不正常或接線錯誤等原因造成設備的損壞。
②第二層次：控制室內部系統調試
此層次在不連接控制至現場電纜情況下，對DCS機柜、PLC柜、火警盤等的系統調試。對于其中的聯鎖系統調試能否做早、做好、做扎實，對“消除隱患、掌握主動、贏得時間”意義重大。
③第三層次：全裝置儀表二次聯校
根據現場施工及工藝試車進度要求，逐點連接控制室至現場電纜，通過在現場加信號進行回路試驗，并陸續投用。
④第四層次：應用軟件參數的進一步調整
此為在單體試車、聯動試車之前、之中、之后，對某些儀表參數如復雜調節系統的計算系數、偏置值、延遲時間、設定值及比例、積分、微分時間等的試驗調整，以獲得最佳運行工況。
