Additional calculation triggering

[Artos9]

Hello,
My system requests to write archival data to ArchiveDAT files.
Writing of pure data works correctly based on “Integration with Rapid SCADA” article.

I haven’t idea how to run channels, which are calculated by formulas and finally write calculated data.

Could you release short part of code how to execute calculations or write some tips?

Thanks you so much.

ArchiveDAT .dat files only stores the final value.
You will need to calculate the value on your program, then write the value to the file.

I usually write a script to convert my legacy data from other system to a excel with 2 sheets, (x axis for cnl no., y axis for datetime), 1 table for value, 1 table for stat. Then I write formulas in excel to calculate the data, and modify data manually if needed.

Then run another program to convert excel to scada .dat file.

Hello,

Formulas are applied automatically by the Server service when you write data using TCP.

Hello,
So if I use function “SendArchive” and send value 10 on channel 101.
Channel 102 is calculated real and use formulas (Val(101) * 2).

Channel 102 will be changed after using function?

Thank you.

I can answer for myself. I tested it and …
It works!

Very good SCADA system!!!
Thank you!

How is the Archive .dat file decrypted on V6? I managed to decrypt the V5 but not V6. Is there a source code available?

You can find file formats here. The source code also available. If you need getting data directly from archives, I suggest using PostgreSQL or InfluxDB archives.
