Hi Billy,

The PS Product block is only for physical signals that come out of Simscape sensor blocks. What you have coming out of the "From" block is a Simulink signal.

You should therefore be fine with a regular Product block from "Simulink -> Math Operations" library to connect all that together.

Yes -- the PS Product block works on physical signals, which are used for input/output to Simscape blocks. You can tell the difference because physical signal ports are white triangles and Simulink signal ports are black arrowheads.

You cannot directly connect physical and Simulink signals unless you use converter blocks (PS-Simulink or Simulink-PS Converter).
