How do you do long-term archiving with WinCC flexible?

  • Entry
  • Associated product(s)
This FAQ response describes how to create and use tag archives the size of which is not restricted by the system limits of the panel.

The system limits for archiving tag values on operator panels and PC Runtime systems permit only restricted long-term archiving.
In the case of an MP 277 Touch, the limit is 10,000 entries per archive (including all the archive segments).

Furthermore, there are restrictions to the output of logged tag values by means of a trend view over a long period of time.
The time period depends on the maximum number of process values that can be stored in the tag log.

This present entry describes how you might be able to use WinCC flexible to

  • Do long-term archiving (Fig. 1).
  • Create tag archives whose names are created first at "Runtime".
    The tag archives created can then be selected via a selection field and output by means of a trend display (Fig. 2).

Fig. 1 shows an example of how the archived entries are displayed. The names of the archives and the "folder structure" are created automatically via scripts.

Fig. 02 shows a trend display. You select the separate archives by date and time.
