Simulink TCP/IP Client Send/Receive

Simulink TCP/IP Client Send and receive works on same computer but not between 2 computers any suggestion? If I write a code it works but not using Simulink

This matlab code working between the same 2 computers fine:

PC1:

t = tcpip('192.168.10.203', 50000, 'NetworkRole', 'server');
fopen(t);
k = 1;
while t.BytesAvailable == 0
   fprintf('Found Data %d\n', k);
   k = k + 1;
   pause(.05)
end
data = fread(t, floor(t.BytesAvailable / 8), 'double');
fprintf('Server: %.12f\n', data);
fprintf('Done...\n');

Output:

Found Data 1

Found Data 2

Found Data 3

Server: 3.141592650000

Done...

Elapsed time is 2.849084 seconds.

>>

PC2:

data = 3.14159265;
fprintf('Client: %.12f\n', data);
t = tcpip(192.168.10.202', 50000, 'NetworkRole', 'client');
fopen(t);
pause(1);
fwrite(t, data, 'double');
fprintf('Done...\n');

Output:

Client: 3.141592650000

Done ...

Elapsed time is 0.104154 seconds.

Screenshot01: This works in the same compute no issues

Screenshots02: The same setting 2 different comuters not working no error no worning.

Any Help will be appreciated.

Updated: Attached samePC_example.slx this can be breaked into send/recieve to acommodate 2 different PCs (for sure you will need to adjust IP addressing) aslo you will need to run this command

echotcpip('ON', 50000);

to enable the socekt in matlab

Can you provide your Simulink model

thanks for your reply, I updated the original post by attaching an example, please let me know if this helps.

Hi,

The TCP/IP Client Send and Client Receive blocks are both client blocks, operate only in TCP/IP client mode (they need to connect to a TCP/IP server) These blocks do not support TCP/IP server functionality. You can use a MATLAB function block to achieve the communication or UDP Send and UDP Receive blocks.

This issue is known and the concerned parties may be looking into it.

Dear Rajani, Do you know if this issue have been solved? I still having it. Thanks in advance for your help and support.
