Code for connecting two Simscape blocks

I am trying to connect two Simscape blocks. My first step is to get the corresponding handles for both blocks with e.g.
>> A=get_param('Pressure/FixedOrifice','LineHandles')
and analog for the second block.
Then I try to connect the blocks via
>> add_line(A.RConn(1,2),B.LConn(1,2))
since the blocks have more than one RConn/LConn. This gives me an error. How do I adress the ports correctly?
Thank you for your help.

We have posted an example on the MATLAB Central File Exchange that shows how to use MATLAB commands to add Simscape blocks and connect them.
I bet you can reuse some of the code in this example in your work.
Thanks,

This did not work because Line Handles gives you handles to lines that exist. If you look at the struct A, it has the values "-1" for LConn and RConn indicating that there is no line connecting those ports.
Instead you need to use the parameter "PortHandles" when using get_param.
B1 = get_param(gcb,'PortHandles') % Port handles for first block
B2 = get_param(gcb,'PortHandles') % Port handles for second block
add_line(gcs,B1.RConn,B2.LConn)
For more details see the last section of the description part of the add_line documentation page: http://www.mathworks.com/help/simulink/slref/add_line.html
Hope this helps!
