Connection to NX Mechatronics Concept Designer not working

The connection is done from a Matlab COM server that must be recognized by Siemens NX and then it's possible to link the NX signals to the Simulink In and Out ports. Once everything is ready and the NX and Simulink models are running, they seem not to be "listening" to each other, despite the links are already done.

What I mean is that when e.g. the NX model sends a signal to Simulink model or vice versa, no reactions are performed.

What could be done to find possible errors? Has someone here already tried to connect these tools? If so, did it work?

Thank you all,
