How should the continuous historian administration of deltab be used?
Thread Content
How do I use the continuous historian administration in Deltap? For example, if I want to check a trend record from a year ago, it’s obviously already archived. It’s not possible to view such trends directly in Deltap; they need to be loaded into Deltap using the software mentioned above. So how should this be done? Once loaded, can I still view the trends directly using the relevant function? Thank you!
Is no one answering? Waiting for a master to appear!
Open continuous historian administration; there is a GREATW EXTENDED HISTARY DATA SET in the tool. In the pop-up window, select the archive file; the date will be the period you want to view. Then it can be adjusted.
This is a standard procedure; it must be an archived file with a date that falls within the specified range. It works fine every time I try.
The storage space for current files is only 10G; any excess data will be removed. Is your space already full and data has been deleted? You need to manually import it as an extended file.
It was imported manually, which means it wasn’t extruded, right? But it just doesn’t work. Moreover, I can’t display events simultaneously when adjusting the trend; otherwise it freezes, and it seems there’s something wrong with the database.
