SIMATIC WinCC Open Architecture Forum

Hello!
I have a question from my collegue (she at commissioning now):
"I'm trying to configure value archive, which will contain floating point values for about 650 dp elements (tags). Values coming to archive on event (statistically there is no more then 3200 values per hour for one dp). I'm little bit confused about what settings and type of archive i need to use. I want make values persistent during one month, but now first taken values disappear after 6 hours."
Thank you!

Please check the settings in the tab "Time" for the archive configuration.
In this tab you can define when a fileswitch shall be made and how many files shall remain on disk before they are deleted.
