How to set Simulink block parameter equal to the value of a signal?

5 views (last 30 days)
I have a tcp client in the subsystem and I would like to set the ip and port value, according to the subsystem input signals. In this way, I would be able to configure my client directly through the input signals. It's something possible?

Hi Davide,
I understand that you are trying to change the block parameters of a certain block, during simulation, depending on the value of the input signal.
This is achievable using the 'set_param' function in matlab. 'set_param' function can be used to set the block parameter values programmatically. You can have a 'matlab function' block in your model ,prior to the subsytem , inside which you can execute the 'set_param' function to set the block parameter values according to your need.
However , it is not considered a best practice to change the block parameter values during runtime. You can refer to this article to get a better understanding on this :

You may include the following line of code to avoid this error.
Hope this helps.
