correct data point's value using Control's script

[MassEffect]

Hello,
I have a data point's archive, how can I correct my data point's value at a certain point of time using Control's script?

For example,
at first I use dpQuery() function for getting next archive's values:

MyDataPoint.myElement:_online..value = 150
MyDataPoint.myElement:_online..stime = 2020.09.04 12:15:00.350

then if I want to corect them I have to use correct values like these

MyDataPoint.myElement:_corr..value = 190
MyDataPoint.myElement:_corr..stime = 2020.09.04 12:15:00.350

but what functions or steps do I have to use for setting these correct values?

As far as I know then I could use dpQuery() fucntion with _offline's config element of MyDataPoint to see a result:

MyDataPoint.myElement:_offline..value = 190
MyDataPoint.myElement:_offline..stime = 2020.09.04 12:15:00.350

Assuming the variable Ttime has the value of MyDataPoint.myElement:_online..stime

Code: Select all

dpSetTimed(Ttime,"MyDataPoint.myElement:_corr..value",190);

Thank you so much!

Another small question)
How can I remove any changes that was added using the function dpSetTimed(Ttime,"MyDataPoint.myElement:_corr..value",190)?

There is no possibility to delete values which are already saved in the WinCC OA archives.
You can only modify an existing value by writing a correction value for the same time again.
