MATLAB: Creation of Simulink Libraries

librarysimulink

Hello all

I have created a Simulink library but the library I created is linked to its block. I want to have it such a way that all the blocks which I am using in a model from this lib must be unlinked. So that any further change either in Model block or Library should not have any effect on each other.

It should be in such a way that it's block should be unlinked from the library the moment it is used in a model.

Hope to hear from you guys soon.

Best Regards

Yes, you can do this.

When you drag a block in from a library, it essentially copies and pastes it into your new model. So, the key is to programmatically disable the library link when this block is copied.

To do this, you can right-click your block and go to Properties. Then, go to the Callbacks tab. Then, add the following line to your CopyFcn callback:

>> set_param(gcb,'LinkStatus','inactive');

Does this work?

MATLAB: What does Resolve link and break link do

First off, here's the documentation resource: http://www.mathworks.com/help/simulink/ug/working-with-library-links.html

When you drag a library block into a model, you can't directly modify it inside that model. The idea is that the block should be modified in the library, and not in the model that references the library.

If you right-click the block in your model, however, you have the option to disable the link. When you do this, you are now able to modify the block in your model.

When you make changes to a disabled library block, it then becomes different from the original library block. If you select resolve, you can choose to push your local changes to the library or restore the block to how it originally was in the library.

Alternatively, you can break the link to a disabled block, which completely disconnects it from the library it originally came from. It is now a standalone block that has nothing to do with the library.
