Boolean values are interpreted in calculations as numeric values 0 and 1.
- Sum
Returns the sum of the numeric values for the calculation period. - Count
Returns the number of values within the calculation period. - Average
Returns the arithmetic average of numeric values for the calculation period.
All values are weighted the same. The result can be a floating-point number. - Min
Returns the lowest numeric value within the calculation period. - Max
Returns the highest numeric value within the calculation period. - First
Returns the first value within the calculation period. - Last
Returns the last value within the calculation period. - Counter
Returns the summed value changes of numeric values within the calculation period.
With an up counter, only positive value changes are summed. Negative value changes are interpreted as a counter reset.
In the case of a down counter, positive and negative value changes are summed.
More precise settings can be made at the variable via the counter settings. - Step duration
Indicates how long the variable has a value and is thus not equal to 0.
Time that the variable actively supplies values. - Timer
Returns the time during which a value was not "false" (FALSE, NULL or empty string). - Time weighted average
Returns the time-weighted average of numeric values for the calculation period.
The values are weighted differently, depending on how long they have been present. The longer a value was present, the more it is weighted. - Standard deviation
Returns the standard deviation of numeric values within the calculation period. - Variance
Returns the variance of numeric values within the calculation period.
