How do you add physical signal lines programmatically?

I just need to connect a Simulink-PS Converter to a Connector port in a subsystem, but the usual add_line function doesn't work. It returns an error, saying the object doesn't exist.

add_line('mymodel/mySubsystem','C_1','Conn_1', 'autorouting', 'on');

This is the specific error:

Invalid Simulink object name: C_1/1

Figured it out. Simscape blocks use "/RConn1", "/LConn1", etc. to denote ports, while Simulink blocks use "/1", "/2", etc. The converter blocks use both depending on which side you're referencing.

use h1 = get_param('mymodel/mySubsystem/C_1','PortHandles'); to get the port handles. Use add_line to draw line between the handles. Refer to Connect Blocks Using Port Handles section at https://www.mathworks.com/help/simulink/slref/add_line.html?searchHighlight=add_line&s_tid=doc_srchtitle

Hi,

i'm facing the same issue. But neither of these variants work:

'PS-Simulink Converter1/1' or  'PS-Simulink Converter1/LConn1'

Is there a simple way to display all ports? What does the following information tell me?

get_param('model/PS-Simulink Converter1','PortHandles')

      Inport: []
     Outport: 91.0541
      Enable: []
     Trigger: []
       State: []
       LConn: 92.0541
       RConn: []
    Ifaction: []
       Reset: []

Thank you in advance

I just figured it out. As long as the connection rules are fulfilled you just have to find the right connectors.

In this case, the following solution works:

port1 = 'Voltage Sensor/RConn1';
port2 = 'PS-Simulink Converter1/LConn1';
add_line(sys,port1,port2);
