This chapter describes the Origins module. This module has been integrated into the time series browser and enables centralised work parallel to evaluation functions and the plausibility module.

"Persistent origins" are calculation rules (formation rules) for time series. "Persistent" stands for time series that remain in the system permanently, as opposed to temporarily created time series that are automatically deleted on a regular basis.

Such a formation rule specifies how defined source time series are to be calculated with each other according to a formula in order to obtain the measured values of the target time series.

You can define up to ten source time series depending on the origin type.

When you create a new time series, this means creating an origin for this new time series so that it can be calculated from a source time series.

Example:

The time series "daily mean values", for example, can be calculated from half-hourly mean values.

In this process, a value of the new time series is formed from the mean values of one day. The average value of the next day results in the next entry.

The origins comprise the following options:

▪Call up origins

▪Structure of the dialog

▪Calculation formulas and Boolean formulas
