處理過程 PLC 代碼。它使用羅克韋爾自動(dòng)化的 Studio5000 Logix Designer 軟件，編程語言為梯形邏輯。

在編程的早期階段就開始使用的測試過程，有助于調(diào)試整個(gè)系統(tǒng)時(shí)的耗時(shí)工作，以及確保應(yīng)用程序的成功開發(fā)。

在某些復(fù)雜的情況下，項(xiàng)目終內(nèi)部測試或現(xiàn)場調(diào)試階段可能需要額外的資源。正確定義應(yīng)用程序并確保其組織合理，有助于實(shí)現(xiàn)近乎無縫的過渡。

在項(xiàng)目調(diào)試階段，可能會(huì)有未參與項(xiàng)目開發(fā)的人員介入進(jìn)來。雖然這并不理想，但只要遵循項(xiàng)目執(zhí)行流程并進(jìn)行的交接，這些新人應(yīng)該可以很快接手。

雖然有幾種不同的編程語言，但常見的可能還是梯形邏輯。有些應(yīng)用程序使用結(jié)構(gòu)化文本編寫，而有些應(yīng)用使用功能塊。在向初以結(jié)構(gòu)化文本編寫的現(xiàn)有PLC添加功能時(shí)，可以使用結(jié)構(gòu)化文本。

功能塊可用于某些任務(wù)，例如模擬輸入濾波或比例-積分-微分（PID）回路。然而，某些供應(yīng)商的軟件包可能需要特定許可才能使用功能塊編程。如果由于當(dāng)前軟件許可的限制，終用戶無法訪問，那么使用功能塊將會(huì)限制未來查看和修改程序的能力。

在系統(tǒng)投入運(yùn)行后，工程咨詢公司使用的編程語言應(yīng)易于對客戶提供支持。為終用戶提供他們無法訪問和維護(hù)的專有應(yīng)用程序反而會(huì)幫倒忙。應(yīng)用程序的佳語言是在項(xiàng)目結(jié)束后客戶滿意的語言。
