blockMinAccumulatedDuration2
Extends from Interfaces.PartialCheckInSlidingWindowWithBooleanOutput (Interfaces and icon for check block that evaluates a property in a sliding time window and returns the result as Boolean).
Information
Syntax
property = MinAccumulatedDuration2(check=..., window=..., lowerLimit=...).y;
Description
In any (sliding) time window of length window, the accumulated time duration where the Boolean input check was true (= accumulatedDuration) must be ≥ parameter lowerLimit. Whenever this property is fulfilled, Boolean output y = true. If this property is not fulfilled at the end of a sliding time window, y = false (even at the first window):
y = if accumulatedDuration ≥ lowerLimit then Satisfied else
(if first then Undecided else Violated);
Violated, Undecided, and Satisfied are elements of enumeration Property.
Example
The property is demonstrated with the following example calling the block as:
