Models contain one of two types of parameters in NI VeriStand:
After you add a model to a system definition, you can identify whether a parameter is global or local by observing its expression, as displayed in the System Explorer window when you select the parameter in the configuration tree. The expression of a global parameter also indicates whether its scope is at the target level or the model level. The following table shows how a parameter expression changes depending on its type and scope. Note that the name of the owning model in the system definition is Sine Wave.
|Local parameter||Sine Wave/Block1/Amplitude||The root of the Amplitude parameter is a block rather than a model.|
|Global parameter, model-level scope||Sine Wave/Amplitude||The root of Amplitude is the owning model.|
|Global parameter, target-level scope||Amplitude||The root of Amplitude is not a specific model.|
|Note A parameter expression contains the model name that appears in the System Explorer configuration tree. Every parameter also has an associated path, which contains the name under which the model was compiled. The following excerpt from the parameter configuration page for previous example shows the path and expression for a global parameter with model-level scope.
