Extracting Data from PI Historian

The Historian ETL PI Extract tool extracts data as follows:

1. Extracts data related to tags into text files, which are named in the following format: YYYYDDMMHHRR_<onsite Historian computer name>.txt. These files are stored in the following folder: <Historian ETL installation location>/Historian ETL PI Extract/HistFiles.
2. After a specified number of files are extracted (by default, 6), the files are compressed into a .zip file, which is named in the following format: YYYYDDMMHHRR_<onsite Historian computer name>.zip. These files are stored in the following folder: <Historian ETL installation location>/Historian ETL PI Extract/ZipFiles.
