blockMaxDuration
In every sliding time window, the longest time duration where check was permanently true must be below an upper limit
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
maxDurationLimited = MaxDuration(check=..., window=..., upperLimit=...).y;
Description
In any (sliding) time window of length window, the longest time duration where the Boolean input check was permanently true (= maxDuration) must be ≤ parameter upperLimit. Whenever this property is fulfilled, Boolean output y = true, otherwise y = false:
y = maxDuration ≤ upperLimit;
Example
The property is demonstrated with the following example calling the block as:
