DCS日常維護時需要對哪些數(shù)據(jù)進行備份？0-51378-25需要對組態(tài)、PID參數(shù)、工藝參數(shù)（設(shè)定值）、系統(tǒng)安裝軟件、電腦驅(qū)動以及認為重要的趨勢、報表等數(shù)據(jù)進行備份。 0-51378-25DCS系統(tǒng)某測點信號（溫度、壓力或流量等）顯示故障應(yīng)如何快速排除？
0-51378-25 信號顯示數(shù)據(jù)不準或無顯示是可能常遇到的問題，它可能由于現(xiàn)場儀表引起，也可能由于DCS引起，可采取快速判斷的方法有： 1、用信號發(fā)生器模擬標準信號測試（前提是現(xiàn)場必須有信號發(fā)生器可使用）或?qū)⒘硪煌愋托盘柧€纜改接到該通道信號引入測試，若正常表明DCS正常，再檢查現(xiàn)場進DCS信號是否有誤。 2、檢查信號線正負是否接反、卡件跳線設(shè)置是否正確（特別是新增點），組態(tài)型號、量程、補償?shù)葏?shù)設(shè)置是否有誤。 3、檢查該信號所屬卡件其他測點運行是否正常，并根據(jù)現(xiàn)場實際情況判斷是否可采用對該卡件備件更換的方式檢測是否為卡件故障，更換時注意跳線設(shè)置
某操作站監(jiān)控有時候會自動退出，是否異常？ A： 系統(tǒng)退出的原因有很多，幾個月偶爾退出1次，屬于系統(tǒng)正常情況，因為如果計算機內(nèi)存占用過大或運行程序過多有可能影響監(jiān)控退出。但如果頻繁退出（比如每天或每周）則不正常。一般系統(tǒng)退出主要有如下幾種原因： 1、系統(tǒng)軟件安裝不規(guī)范，重新安裝后可以解決。 2、同一個時間恰好出現(xiàn)了多個報警，導(dǎo)致計算機系統(tǒng)的資源不足報錯。 3、系統(tǒng)調(diào)用的組態(tài)路徑為網(wǎng)絡(luò)路徑，非本機路徑。
What data needs to be backed up for daily maintenance of DCS? A: It is necessary to backup configuration, PID parameters, process parameters (set values), system installation software, computer drivers, as well as important trend and report data. Q9: How to quickly troubleshoot the display of a signal (temperature, pressure, flow rate, etc.) at a certain measuring point in the DCS system?
A: Inaccurate or no display of signal display data is a common problem that may be caused by on-site instruments or DCS. Quick judgment methods include: 1. Simulate standard signal testing with a signal generator (provided that there must be a signal generator available on site) or connect another type of signal cable to the channel signal for testing. If it is normal, it indicates that DCS is normal, Recheck if there are any errors in the DCS signal on site.
Check if the positive and negative signals are reversed, if the jumper settings for the card are correct (especially for newly added points), and if there are any errors in the configuration model, range, compensation, and other parameter settings. 3. Check if other measuring points of the card to which the signal belongs are operating normally, and determine whether it is possible to use the method of replacing the spare parts of the card to detect whether it is a card fault based on the actual situation on site. When replacing, pay attention to the jumper settings
Is it abnormal that the monitoring of a certain operation station sometimes automatically exits? A: There are many reasons for system exit, with occasional exits occurring every few months, which is a normal situation for the system. If the computer's memory usage is too large or there are too many programs running, it may affect monitoring exit. But frequent exits (such as daily or weekly) are abnormal. There are several main reasons for system exit: 1. The installation of system software is not standardized, and it can be resolved after reinstallation. 2. Multiple alarms occurred at the same time, causing the computer system to run out of resources and report errors. 3. The configuration path for system calls is a network path, not a local path.
