Creating an f(x) Trend View for Comfort Panels and WinCC Runtime Advanced
https://support.industry.siemens.com/cs/document/109481693/
An f(x) trend view in WinCC Comfort/Advanced always offers this option. However, it is not independent in terms of time, since the value pairs of x and f(x) are assigned based on the recorded time stamp.
When using an f(x) trend view there are therefore the following restrictions:
Both time stamps of the value of a pair have to be absolutely identical.
Archive tags have to be acquired “cyclically-continuously”, when archiving “On demand” (different time stamps) there is no display.
Array tags are not supported.
The display of the data points of an archive in the f(x) trend view presupposes the correct format of the archive data. This is ensured by the use of a script.
The script ensures that in the tag archive
two arrays of real values (X value and Y value) are stored in the controller as a series of individual values.
the individual value pairs are stored with an identical time stamp.
the values can be archived “On demand”.
the structure is according to a standard archive.
