In administrator – Instances – Server – Saving parameters, you can choose the save interval for minute data.
The options available options can be as low as per 30s.
in the project folder, you edit the following file,
change the following line
<Param name=”WriteMinPer” value=”60″ descr=”Minute data writing period, sec” />
fill in value=”1″.
It will save data in ArchiveDAT/Min folder per 1 second on my test.
But be very careful, I am not sure if there will be any negative impact.
I suspect it can slow down or even crash the server when you download minute report or plot chars.
you solved my problem,but have you tested dbexport module to save data into other database and i also write a driver to export curdata into influxdb with code oncurdataprocessed. thanks a lot
I haven’t try dbexport module.
But I did read and push cur data to other services. I have a separated service to do this instead of a scada driver, to avoid crashing scada.
A tip for this type of action is set Cur folder to ram disk, which make the process faster.
