[?]: import data from csv file to Historian Server

[MS_PLC]

Hi!

I am a green hand in development.
Now I want to pass data from csv file to Historian Server.
As I understood, if I want to import data then I need to copy csv-files to the appropriate directory.
And I have a question. When does Histrioan read these files?
Immediately after the file will placed to this directory or there is a special mechanism of import?
