Hi,
To use the 2 instances of the referenced model with different parameters which are non-tunable, you can
(a)Define a model argument Modelling > Model Settings > Model Properties > Model Referencing tab and add your parameters under Model arguments. For example, you might add an argument named initialID.
In the Model block (the instance of your referenced model in the parent model), specify the value for this argument in the Model arguments field found in the block's parameters. You can enter the specific value or use a workspace variable. For example: initialID=1 for the first instance and initialID=2 for the second.
With this approach you pass the initial ID setting as a non-tunable parameter since the model argument's value is set before simulation starts and cannot be changed during simulation.
(b) Use a Preload function script to set up different parameters for each instance of the referenced model by creating a MATLAB script that sets the parameters in the base workspace or model workspace before the model is loaded.
Using this script assign values to variables that correspond to the parameters in your referenced models.
Ensure this script is executed before the model runs. You can set the script to run automatically by including it in the model's Preload callback (in Model Properties under Callbacks).
You can refer the below link for more information on Model referencing
Hope this helps.
