Hi Vivek,
You have to generate the RTD code in the .mex configurator first.
The project can be compiled once you have the RTD folder in the project.
1. Yes, we cannot guarantee the functionality with RTDs that has not been tested.
2. unfortunately, there is no IPCF for RTD 4.0.0, there is IPCF for 5.0.0 and 6.0.0
3. let me check on that, I will update the thread as soon as possible.
Best regards,
Daniel
