Copy a CSV file into an import folder

After you copy one or more CSV files to an import folder, the AVEVA Historian attempts to read the file(s) only one time. If the read is successful, the data is automatically converted and merged in with the appropriate history block according to the date range provided in the CSV file. The CSV file is then deleted from the directory. If an error occurs during the import, the CSV file is moved to the \Support folder. A message is also posted in the error log.

At any given time, the manual storage service processes either fast load CSV files or normal CSV files; the two types are not processed concurrently.

Do not attempt a CSV file import if the manual storage process is initializing, as indicated by the icon in the status display of the Management Console.

Be sure that the access for the history blocks is read/write (if you copy them from a CD or DVD, for example, they are read-only).
