Sending over TCP/IP from simulink to a localhost.

I am trying to send data from my simulink model to a server running on the same computer. The server is running on the localhost port 8080. My problem is that when I try to configure the TCP client block the client and remote server IP address are the same. As my server and Simulink are running on the same computer. All the examples I have come across are about sending data to a target/remote PC. Can anyone help me with achieve my goal.

To send data from the simulink model to a server running on the same machine, you could just specify the remote address as 'localhost' and the remote port as 8080 for the Simulink TCP/IP Send block parameters.

I was using the TCP/IP blocks from simulink realtime. But according to my understanding those blocks will only send data to a physically connected target device. I found another block TCP/IP Client Send block in the Instrument Control Toolbox in Simulink. With this block I am able to send data to my node.js server.

This MathWorks tutorial explains how to use the TCP/IP blocks.

At the moment I am seeing this in my console. I am not sure how to parse it to the correct format. But working on it.
