Simulink Coder + Referenced Models with arguments

Hello,

I have a model with severel instances of a referenced model and all the parameters of these instances shall tunable indiviually. I did this by setting the check box "argument" in the referenced model.

As referenced models are in there, these models also need a Simulink configuration. Therefore I linked the referenced model to the Simulink data dictionary of the main model and refered to the the configuration of the main model.

Now I want to generate code from the main model including the instances of the referenced model, but I get the follwoing error messages:

The code interface packaging option 'C++ class' cannot be selected for model 'Model' because it does not combine its output and update functions when generating code for model reference targets

or

Invalid setting in 'Model/Transfer Fcn' for parameter 'Denominator'.

Caused by:

• Model arguments can not be used in non-tunable expressions. The expression '[T 1]' in parameter 'Denominator' of 'Model/Transfer Fcn' can not be tuned but it refers to variables (T (model argument)). For more information about non-tunable expressions, see the documentation.
• The generated code will inline the numeric value of the expression '[T 1]' (used in parameter 'Denominator' of 'Model/Transfer Fcn') because the expression has one or more unsupported operators (see the documentation). The code for this block will not use the tunable variables (T (model argument)).

I figured out that it got something to do with the code interface packaging option. Therefore I tried to use different configurations for this. But this part of the configuration can't be override for some reasons, so I can't refere to the main configuration and have to do setup an own configuration for the referenced models. Is this right way? I somehow think that there must be a better solution for this.

I hope someone can help!

Best regards and thanks in advance!
