Hi, I would like to know if there is any way to convert block parameters into input ports? For example I have a Multi-Port Switch and I would like to enter the "Number of data ports" as an input:
I know we can control this parameter through Matlab workspace, but I'm wondering if there is any way to control through an input.
Thanks, --Kash

Hi Khashayar,
It depends on the blocks you are working with. For example, in your case of a Multiport Switch, this is possible. Simply connect the first inport with a constant block. The value of the constant block will determine the number of inputs for the Multiport Switch. The value of the Constant block can be extracted as follows:
str2double(get_param('testModel/Constant', 'Value'))
I am attaching the screenshot "testModel.png" for your reference.
Thanks,
David

David,
Is there a way to convert block parameters - Integrator High limit and Low limit - into the input signals to the Integrator block?
Appreciate your response.
Thank you,
Arshad S.

Hi David, You're right, it depends on the block. I'm using embedded coder for TI c2000 microcontrollers and would like being able to change the Message identifier and Message type dynamically while the software is running:
I guess the only way to control these two parameters dynamically is to define two inputs so I would be able to feed them with desired values. But I think it's impossible in Simulink.
