Saving the basic archive

On the fourth page of this dialogbox we define, how the archive files should be saved.

We save our basic archive in the Internal database (i.e. in the zenon format). So we can use the data stored there in other modules (e.g. Report Generator or Extended Trend Module) later.
Set the saving cycle to two minutes.

Thereby we get seperate files for every two minutes. As we set the scan cycle to ten seconds, we will get twelve values of each linked variable in one archive file.

Info

Generally speaking this setting has hardly any effect, if you only work with basic archives. You always access archive data with filters (e.g. time filters) and zenon automatically takes care that the correct files are opened.

But already here your define the scan rate for a following archive!

In the section Ring buffer select that our archive files should no be evacuated. The files should be kept for one day.

Info

zenon writes the archives in a ring buffer, which we define here. This should guarantee that we have no data overflow on the harddisk. If you export or evacuate (i.e. before they are deleted, they are automatically exported as dBase or text files) archives, you have to care for the space on the harddisk on your own.
