PartialInputCheck	Assert when condition is violated

Buildings.Utilities.Diagnostics.BaseClasses.PartialInputCheck

Information

Partial model that can be used to check whether its inputs satisfy a certain condition such as equality within a prescribed threshold.

Extends from Modelica.Blocks.Interfaces.BlockIcon (Basic graphical layout of input/output block).

Parameters

Type	Name	Default	Description
Time	startTime	0	Start time for activating the assert [s]
Real	threShold	1E-2	Threshold for equality comparison
String	message	"Inputs differ by more than ...

Connectors

Type	Name	Description
input RealInput	u1	Value to check, equal to 0 if unconnected
input RealInput	u2	Value to check, equal to 0 if unconnected
