I would like to send and receive data inside target computer(xpc target) by setting the Ip adresses of udp send and receive blocks as '127.0.0.1'. When I run the system as software in loop, It works.However, after compiled the model, that blocks didin't work. Is it possible to do that ? or Should I use different way to make it possible ?

Could you confirm that you want the same xpc host to send and receive the data?
If I understand correctly, xpc requires a dedicated program running on a real-time operating system, so if I understand correctly, you cannot have two different programs running on the same xpc exchanging data. As such you are setting up a loopback. Is that your intention?

Yes. Absolutely ,I would like to do that . To clarify , for example, I can use "goto-from" blocks to move a signal from a subsystem to another subsystem inside the same model, but at this time I would like to send data by using the udp send and receive block inside the same model instead of the goto block or signal. So that my udp sender and receiver will be in the same model for transferring data. Shortly,I don't want to have two different programs running on the same xpc.Only, I want to run a model which has udp send and receiver to move data inside model, on the same xpc.
Is it clear now?

Hi Yavuzhan,
You can achieve this by using the UDP Send and UDP Receive blocks from the Simulink Real-Time library (see here for examples in R2020a and earlier / here for R2020b and later). Please note that the UDP Send and UDP Receive blocks require the IP addresses of the corresponding Ethernet ports to be in different subnets.
If you're using MATLAB R2020b or later, these Ethernet ports should also be configured using the Speedgoat Ethernet Configuration tool before you deploy your model.
I hope this is helpful!

Sorry, I do not have anything resembling appropriate hardware to test this with, and I do not have access to the source code.
