MATLAB: Link blocks in different libraries[Fuel Cell Stack(Specialized power system) and Motor & Drive (Simscape electrical)

fuel cell stackmotor driveSimscapeSimscape Electricalspecialized power system

The two blocks contained in the two libraries with red circle respectively.
I want to link the two blocks together as they are the key components in my model. However, it failed as they located in differrent libraries.(one with the Blank square port another with the gray one).
Could anyone tell me how to link the two components together(like use a converter to transform the data) or if there's any substitute for the two blocks that in the same libraries?

Best Answer

I fonund this bolck is more efficient as it can transform the signal directly.
