blockBoundaryMap
Block which returns false if the input parameters are out of the given charasteristic map.
For the boundaries of the y-input value, a dynamic hysteresis is used to ensure a used device will stay off a certain time after shutdown.
Extends from AixLib.Obsolete.Year2024.Controls.HeatPump.SafetyControls.BaseClasses.BoundaryMapIcon.
Information
Given an input of the x and y-Axis, the block returns true if the given point is outside of the given envelope.
The maximal and minmal y-value depend on the x-Value and are defined by the upper and lower boundaries in form of 1Ds-Tables. The maximal and minimal x-values are obtained trough the table and are constant.
