Error #15300: No compiled data for the block available while generation code with target link which model includes user libraries.

-> I am doing automation on simulink model which includes targetlink blocks(which also have user defined library blocks). As per my requirement I am editing library model as well and trying to generate code. If my model includes Library models which have function block the code genetation is not happening and throughing Error #15300 error. I have crosschecked my libraries are saved correctly and all the links are correct in model as well.

I fould some unintentional changes on inport and outport blocks after I run my script on model.Please find below higlighted properties which are updating without intention.If I retaine these chages and generating code its susscessfully generating.

Could any one please help how these settings are getting modified and how can we access these propertis trhough script. Info:these are targetlink port used inside simulink model.

Hi Aruna,

While I am unsure about how your script changes the configuration settings, which would require a deep analysis of your script, I can guide you on how to access and modify a property within your script.

• First, you need to identify the "inport" and "outport" blocks in your Simulink model. This can be achieved using the "find_system" function or by iterating through the blocks in the model

    % Example to find all inport blocks
    inports = find_system('YourModelName', 'BlockType', 'Inport'); 

• Once you have identified the ports, you can access and modify their properties using the "get_param" and "set_param" functions.

    % Example to get and set properties of an inport block
    portHandle = get_param(inports{1}, 'Handle');
    currentDataType = get_param(portHandle, 'DataType');
     
    % Modify properties if needed
    set_param(portHandle, 'DataType', 'double');  % Example modification  

For further reading and to understand more about how to use these functions, here are the documentation links you can access:-

Hope it helps!

Thanks for you hint. I am aware of find_system and get_param and using in other script as well, but with these funstions I am not able to get above mentioned properties of block. It will be helpfull if you provide, how can I get above mentioned(DataTypeExpr,DimentionExper) properties of input and output blcok .
