Historical Database File (HDB)
Canary writes a separate Historical Database File (HDB) for each Dataset. The files are saved by default in C:\Historian Data and separated by Dataset. These HDB files can Roll-Over, Roll-Up, and be Deleted.
- Roll-Over: This is how often users would like HDB files created.
- Roll-Up: This is how often users would like HDB files combined/grouped together.
- Delete: This is where users can set the amount of time elapsed before the HDB file is deleted.
