Editing parameter of a block by loading a file element

i'm working with xPC Target tool. I'm using the UDP Send binary block to send data over a network. My question is: Is it possibile set the IP address automatically?

As simulation starts, my model load a configuration file from target HDD, how can I save the IP address in that file, and use it in my model at starting of simulation?

I think to sava it as a string variable, when simulation starts, load that one from file and pass the variable name to the block. Is it a possible way to fix my issue?

hoping to be clear.

PS: I'm just using the configuration file. I load it at beginning of simulation, and save all data in Data memory block. it works fine.

Best Regards
