Indicate unresolved reference to library block
This block indicates an unresolved reference to a library block (see Linked Blocks). You can use this block's parameter dialog box to fix the reference to point to the actual location of the library block.
The Details field contains a description of the cause of the unresolved link. Simulink® tries to help you find and install missing products that a model needs to run. For missing products, the block description provides a link. Click the link to open Add-On Explorer and install the missing products.

Then select Apply or OK to apply the fix and close the dialog box.
