Information

Transformation:

ValuesAfterChangeWithTimeWindow

Transformation Group:

Selection

Description:

This transformation can be used e.g. to filter out measurement values during periods where the measured system is not in a (quasi) steady state due to changes happening in the system. This transformation creates a time window after each change in a configured condition variable. The length of each time window is determined by a custom expression in the configuration. Depending on the configured selection type the input values inside or outside the time windows are selected. All selected input values are then copied to the output variable.

...

When using coefficient set functions (available since build 30246), the value elements can contain tags between "@" signs (e.g. " (NUMBER)") that refer to location attributes that are defined in the locationSets configuration file. The tags are replaced by actual values. These values can be different for different locations and time periods. See 22 Locations and attributes defined in CSV files, Shape-DBF files or external tables for more information.
