Target to Development Computer Communication by Using TCP
This example shows how to use TCP blocks to send data from the target computer to MATLAB® running on the development computer. This example uses a target computer located at IP address 192.168.7.5.
The TCP Send block in the server real-time application
slrt_ex_target_to_host_TCP sends data from the target computer to the TCP/IP object that is created in MATLAB on the development computer. The MATLAB m-script sends the received data back to the real-time application.
To open this example, in the MATLAB Command Window, type:
Open, Build, and Download Server Application
Open the model.
model = 'slrt_ex_target_to_host_TCP'; mdlOpen = 0; systems = find_system('type', 'block_diagram'); if ~any(strcmp(model, systems)) mdlOpen = 1; open_system(fullfile(matlabroot,'toolbox','slrealtime','examples',model)); end
Build Model and Download to Target Computer
set_param(model, 'RTWVerbose', 'off'); set_param(model, 'StopTime','10'); targetIP = '192.168.7.5'; set_param([model,'/TCP Server'],'serverAddress',targetIP); evalc('slbuild(model)'); tg = slrealtime; load(tg,model);
Close the model.
if (mdlOpen) bdclose(model); end
Create TCP/IP Object in MATLAB on Development Computer
Create a TCP/IP object and connect the TCP/IP object to the development computer.
t = tcpclient(targetIP,5027);
Run Real-Time Application on Target Computer
Read Data Packets and Send Back to Target Computer
Read from the target computer and write back.
tic while (toc<5) data = read(t,16); write(t,data); end
Stop Real-Time Application on Target Computer
Close TCP/IP Object on Development Computer
