It is not possible to use "To Workspace" blocks in multi-instance model references. The "Variable name" property cannot be changed in the different instances because it's not a tunable parameter.
Instead, we recommend using Simulation Data Inspector to view and analyze logged signals in referenced models. For example, this workflow might look as follows:
- In your referenced model, right-click the signal you would like to log and select "Log Selected Signal".
- In your top-level model, if you keep all parameters in the Configuration Parameters > Data Import/Export pane set to their default values (i.e., "Single simulation output" enabled and set to a variable named "out"), then you can see all instances of the logged signal by inspecting the variable "out" after simulating the top-level model.
For more information on using Simulation Data Inspector to log signals in referenced models, please see our documentation on viewing signals in model reference instances.
