Hello,

I have a protected model (.slxp) in simulink with 150 inputs and 50 outputs, and a I need to automatize the process of connecting them to other blocks input/outputs. Im trying to get a 2 columns matrix with the string name of the port and the number associated. And later, use the add_line command in a script to connect to others blocks.

I have tried this with a compilated simple model with less inputs/outputs and i get a matrix cell like the following:

block_InPortInfo = 
'Speed'    '1'
'Time'     '2'
'On'       '3'

And the code I used is:

block = get_param('Compiled/Block','Handle');
block_handles = find_system(block,'LookUnderMasks', 'on', 'FollowLinks', 'on', 'SearchDepth', 1, 'BlockType', 'Inport');
block_InPortInfo = [get_param(block_handles, 'Name') get_param(block_handles, 'port') ];

But if I use this code with a protected simulink block the variable

block_handles

is empty [ ].

Is there any way I can retrieve this information of the ports of a protected block in simulink?

Thanks.

You can try using ‘PortHandles’ block property

%Get port Handles
block=get_param(‘Compiled/Block’,'PortHandles'); 
%Get port Info 
block_InPortInfo = [get_param(block.Inport,'PortType') , get_param(block.Inport,'PortNumber') ];

@Bhargavi Maganuru - your solution on gives the port type and number. How can I extract the name. I have a fairly large protected model with many inport/outports. I would like to extract the names of these ports. Using find_system+LookUnderMasks is not a viable option for protected models. Is there another option to programatically get port names for protected models.
