MATLAB: How to find which functions are supported on TCP/UDP functions in xPC Target 3.4 (R2008a)

Simulink Real-Time

I am looking for which functions are supported on TCP/UDP functions in xPC Target 3.4 (R2008a).

Best Answer

There is no documentation for the list of functions supported on TCP/UDP functions in xPC Target 3.4 (R2008a).

However, you can find the functions in the socketfuncs.h file.

You can reach this file with the following command:

cd([matlabroot, '\toolbox\rtw\targets\xpc\target\build\include'])
edit socketfuncs.h

The model on the target can be stopped without the host by pressing "C" on the target keyboard, then typing "stop" to stop the model.

The TCP/IP timeout probably happens when you try to retrieve the files generated by the File Scope blocks. Large amount of data causes TCP/IP timeout. Increasing the communication timeout should resolve the issue.

To increase the communication timeout from the host machine, refer to the code below.

tg.CommunicationTimeOut % Get the current value of the communication timeout.
tg.CommunicationTimeOut = 30 % Set a new value for the communication timeout.

MATLAB: How to resolve the UDP Receive build error

The error indicates that it is unable to find "socketfuncs.h" file. This file is part of the Simulink-Real Time (SLRT), formerly known as xPC. This error appears when we try to build using non-SLRT target environment language compilers such as 'grt.tlc', 'ert.tlc' etc. In order to build successfully without errors, please go to Model Configuration Parameters -> Code Generation and choose 'slrt.tlc' from the browse list as the system target file.

In case you want to still choose non-SLRT target language compilers, the only workaround will be to remove the SLRT target blocks from the model and use blocks that are supported for code generation. We have two blocks for which embedded code generation is supported, however these blocks are part of different toolboxes:
