3 Signals and Parameters
3-4
The Model Hierarchy node can have up to three types of nodes: subsystems
( ) (including their signals and parameters), parameters ( ), and signals
( ). Only xPC Target tunable parameters and signals of the application, as
represented in the Simulink model, appear in the
Model Hierarchy node.
This example currently has only parameters and signals.
Note that if you make changes (such as adding an xPC Target scope) to the
model associated with the downloaded application, then rebuild that model
and download it again to the target PC, you should reconnect to the target
PC to refresh the
Model Hierarchy node.
