While the brown lines represent physical signals, the green/blue lines represent connections within mechanical/electrical systems (imagine wires in a circuit). Hence, connecting them directly to a 'Scope' is not valid (since 'Scopes' are made just to visualize Simulink signal data, and not to read any data from a connection).
You can put sensors to read the data values at any point in those lines, and then view the values in 'Scope' after converting the physical output signals from the sensors to Simulink signals by a 'PS-Simulink Converter'.
A sample model is shown below:
Notice the 'Force Sensor' coupled with the 'PS-Simulink Converter' being used to visualize the data value at a particular point.
Thanks!
