- simulation model is closed - "gcs" returns the path name of the current system. If the simulation model is not open, gcs will return Null. Thus, portname will be empty.
- simulation model is not saved - Ensure that the latest model is saved where the line name is set.
Get SrcPortName from only line handle (without block handle)

How can I obtain the SrcPortName from line handle?
line_handle = find_system(gcs,'SearchDepth', 1, 'FindAll', 'on', 'type', 'line');
handleSourcePort = get_param(line_handle, 'SrcPortHandle')
portname = get(handleSourcePort,'Name')
I got empty variable portname =[], but it should be 'Out1'.
Thank you in advance for help.

Hi Ewela,
The provided code works for me and I am able to get the value in portname. However, playing around with it, I found out that "portname" would be returned empty if:
Furthermore, If there are multiple connections in the simulation model, brace indexing would be needed to get the name of a particular Source port handle. Here is the code to demonstrate the same:
line_handle = find_system(gcs,'SearchDepth', 1, 'FindAll', 'on', 'type', 'line');
handleSourcePort = get_param(line_handle, 'SrcPortHandle')
portname = get(handleSourcePort{1},'Name')
Hope this helps!
