How to delete the recording curve of central control DCS in Zhejiang University ~ ~ The correct answer gives high marks.

Find Trendrecord under the system file RUN. This folder is where trend files are stored! ~

When do you want it? 1. Delete trend. You can't delete it at some time. If you want to delete, you can only delete a whole day or a whole month, depending on the original trend record settings of your DCS.

2. You can (possibly) delete the system trend, but it will not affect the operation.

Finally, I would like to remind you that if you delete your misoperation trend record for exemption, then I tell you that this is likely to be seen through at a glance, unless you are the only person in your company who knows DCS and others don't, you can find an excuse to say that data is lost or something. In fact, DCS misoperation is inevitable. You can't walk along the river without stumbling. . . . Reporting to the leader is not as serious as you think. If you find that the DCS trend record has been deleted and exempted from inspection, don't mix this business in the future.

Of course, I hope this is just my guess. I hope you are just learning to understand! ~
