How to restore the original data of the cumulative values in the DELTAV system
Thread Content
In our factory’s DELTAV system, a sudden power outage caused the cumulative values of some measuring instruments to be reset automatically. How can we restore the original data of these cumulative values?
I’ve encountered similar problems; if the power goes out, all the online data is lost. Personally, I think it’s impossible to restore.
Is it from the instrument itself or from the upper-level system? If it’s the instrument itself, check the manual; only those equipped with a backup battery can retain cumulative data. Otherwise, it will be impossible to restore that data, and one can only rely on the system’s curve records.
In modulel, the real-time data of the cumulative function block was lost, so accumulation has started over again.
Thank you! Our plant uses FF instruments; the field instruments do not have an accumulation function, as accumulation is handled by the DCS system.
Thank you! Our factory uses FF instruments; the field instruments do not have an accumulation function – accumulation is handled by the DCS system. It is understood that this can be modified by adjusting the configuration parameters of the DCS, but I’m not sure how to do it.
We also use FF instruments. It’s not possible to accumulate points yet; we need to check whether the parameters of the score function block are correct, and also examine the parameters of the date and time function block. The configuration method should be similar
