change the position of a part of the input ports of a simulink block.

Hello everyone,

I would like to change the position of the input ports of a simulink block. I need to put them on the bottom of a subsystem block. Does anyone have any ideas for how I can put the input ports on more than one side?

Actually I tried to modify the parameter "port connectivity", but at any attempt I get an error message saying:

*' ModelReference block parameter 'PortConnectivity' is read-only '*

This is the list of instructions that I used "

portData = get_param('ModelName/MySubsystemBlockName','PortConnectivity'); 

portData(1).Position = [newXValue newYValue]; 

      set_param('ModelName/MySubsystemBlockName','PortConnectivity',portData); "

I'm 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 if we cannot use it, and in particular in which cases we have a Simulink block where this option is write permitted?

Any help?

thanks in advance

The input/output ports can be flipped in a simple manner. Select the block, right click on it and then select option Rotate and Flip, and chose the option Flip Block. Thus it flips the input/output ports.

That's it thanks

AFAIK, it is currently not possible to change the positions of input/output ports on a Simulink block. The best you can do it Rotate/Flip your block, but the relative positions of the ports will be unchanged.

That's just what I was looking for, thank u!

Is this answer still correct as of 2020? I believe in 2020b, at most, you can drag and position the ports at the subsystem's parent level. Please update or remove answer.

I can confirm Mikhail that in 2020b, you can freely drag the ports of a subsystem block to any side.

Double click on the input port itself to change its location from right to left using the "Port location on parent subsystem" attribute, after that you may flip your block vertically so the input port would be on the lower side of your block.

[Amit Singh]

You need to right click on the input port you need to change. Select "Block Parameters (PMIOPort)" and there would be option to put port "left" or "right". Please refer the figures for more info.

Hello,

Is there a way to change the location of the port on the parent subsystem programmatically?

Thank you,

Hello guys, Is anyone here know how to change from input conn to output? I don't know if its just norm but i have only the input conn on the simEvent port and subsystem library. Please
