Cumulant Decomposer¶
This stage calculates the delta value between the current record and the last record in the attr
field and the electric energy data. It has a dependency on the Last Record Appender stage.
Configuration¶
The configuration tabs for this stage are General, Basic, and Input/Output.

Input/Output¶
Name |
Required? |
Description |
---|---|---|
Input Point |
Yes |
Specify the input point of the records, using the format {modelId}::{pointId}. For the same configuration row, the modelId must be the same, and the input point and the output point must be different. |
Scale Type |
Yes |
Specify the scale type of the electric energy meter.
|
Scale |
Yes |
Specify the scale of the electric energy meter.
|
Slope Type |
Yes |
Specify the slope threshold type.
|
Min / Max Slope |
Yes |
Specify the lower and upper limits of the slope.
|
Output Point |
Yes |
Specify the output point of the records, using the format {modelId}::{pointId}. For the same configuration row, the modelId must be the same, and the input point and the output point must be different. |
Output Results¶
The specified scale and slope values (fixed value or attribute value) and the calculated record value are included in the attr
struct.
