TP857底座,TP857數(shù)據庫
在升級驅動、軟件前,慎重考慮軟件、驅動、硬件的匹配程度,保證機組、系統(tǒng)的正常運作。
軟件故障通常由軟件編制錯誤所因此,一般出現(xiàn)在DCS 系統(tǒng)投入運行后或者軟件在升級后,大部分軟件程序編制復雜,同時又存在組態(tài)人員交叉作業(yè)等情況,TP857導致軟件錯誤時有發(fā)生,DCS 系統(tǒng)所應用的軟件主要為安裝工作站工具以及監(jiān)控軟件。
? 故障分析:
軟件故障主要體現(xiàn)在以下幾個方面:
①主CPU 組態(tài)、從CPU 組態(tài)信息不一致,CPU 無法正常初始化。
②數(shù)據庫組態(tài)和通道連接信號不能夠實現(xiàn)有效匹配。
③網絡通信阻塞引發(fā)的系統(tǒng)混亂。
④打印機打印失效。
⑤在更換一次元件后,變量參數(shù)設置出錯。
⑤設備不正常工作,系統(tǒng)輸出不能夠正常驅動設備工作等。
? 故障處理:
在正常工作條件下,軟件故障的情況較少,集中出現(xiàn)在修改機組組態(tài)后以及機組調試過程中,應用成熟的軟件是保證DCS系統(tǒng)正常運作的基礎。TP857底座
對此,在進行機組檢修改造前或者調試機組前,必須要落實完善的改造方案,并根據方案內容進行有效的技術交底,確保相關制度的有效落實,避免因人為失誤致使軟件故障。另外,需采用合理的備份手段,避免軟件故障導致數(shù)據丟失。
問題:某企業(yè)采用CENTUM CS1000集散控制系統(tǒng),該系統(tǒng)是基于windows2000 Professional 的結構開發(fā)的新一代DCS系統(tǒng),系統(tǒng)利用可靠的總線實時控制網絡VLNET實現(xiàn)過程控制。系統(tǒng)在升級后,偶爾出現(xiàn)電焙爐溫控回路從自動跳手動的現(xiàn)象,并且出現(xiàn)開路報警。
, the control often failed, (if you don't return to the front limit and continue to run forward, or if you don't stop when you return to the rear limit, the sports car will be damaged, and a large number of travel switches will be replaced every year. The electrician has a heavy workload of maintenance. In order to solve this problem, you decide to use the time relay of logo to control the travel of the sports car and cancel the travel switch that is easy to fail. Now, after nearly one year of use, you have solved the problem that the sports car often can't start and stop due to poor contact of switch contacts The problem of falling off the road.
2. Process flow introduction
The track of the sports car is 3.5m long. It takes 1 minute and 15 seconds to walk from the starting point to the front limit. The return is the same as the forward. When it reaches the rear limit, it should stop, otherwise a timeout alarm will be sent.Flow chart of single automatic control of
