Hello. I want to communicate with a Smart Meter in Realtime over TCP/IP. I use Matlab/Simulink R2016a and Simulink Real Time 2016a on the xPC Target. I wrote a s-function to generate a socket, send and receive datas over TCP. On my host PC in Simulink my model is running well and ich get the correct message from the Smart Meter. But I cannot build this s-function block in Simulink Real Time. I get the following error message:

The call to slrt_make_rtw_hook, during the exit hook generated the following error: Invalid Simulink object name: loader

The build process will terminate as a result. Caused by: Invalid Simulink object name: loader No block diagram 'loader' is loaded.

I attached my s-function. Are the headers (f.e. winsock.h) missing on the Target? How can I solve the problem?

Thank you for any support!
