TOPIC: Storage DB period

Dear Ruslan,
I have some question about Events/History tab DB. How do you see in image attached i have the field at name "Archive since" and "Storage DB period" what is the difference?
I need to show a graph of a trial for 3 minutes. Every second of the graph must be taken and the proof must be available for at least one day. I put 1 day storage DB period as a minimum and as a maximum I thought of putting 1 year. Unfortunately, after 3 days of use I am no longer able to view the graph and the programme crashes.
Can you please explain to me the difference between "Archive since" and "Storage DB period"?.
Thank you in advince.

Greetings.

Dear Anna,
"Storage DB period" is a summary period of storage history information for tags in General database. "Archive since" is a period from which history information will be transfer into the archive database. In this database should be placed history information that's not request very often. "Storage DB period" should be greater then "Archive since" time.

Best regards,
Ruslan
