Thread Subject: How can I change the IO port position on a subsystem block in Simulink?

hi,

I would like to display the input channels on the bottom of a subsystem block so I try to modify the port position of this block , but at any attempt I get an error message saying:
'
ModelReference block parameter 'PortConnectivity' is read-only
'

This is the list of command that I used
"
portData = get_param('ModelName/MySubsystemBlockName','PortConnectivity');
portData(1).Position = [newXValue newYValue];
set_param('ModelName/MySubsystemBlockName','PortConnectivity',portData);
"

Does anyone have any ideas for how I can put the input ports on more than one side?
Having all my input ports on one side makes it harder to identify them

 Feel free to propose a different solution

 

You cannot.

Except for trigger and enable port, all input and output ports are on opposite sides to each other (left-right, up-down, etc depending on the rotation of the block).

Thank a lot for your answer,

I guess you are right but I'm still wondering why we have that option, "PortConnectivity", in the parameters list of a Simulink block:
http://www.mathworks.nl/help/toolbox/simulink/slref/f23-7517.html
and in particular in which cases we can modify it.
 when can a Simulink block be writing permitted?



Is it possible to made a block like the sum?

where we can change the ports position changing its shape
