To monitor and log signal data on the host computer while a simulation is running on a Speedgoat target, consider one of the following options:
Simulation Data Inspector (SDI)
SDI can show signals live while the application is running on the target. It is also possible to export and save data from SDI (to the base workspace or a file) but that can only be done after the simulation run on the target has stopped.

startRecording/stopRecording APIs
If it is possible for you to stop recording data at any time during the model’s execution, as a potential workaround, you may consider using the stopRecording/startRecording APIs when using the SDI.
When you call "stopRecording", the system will stop all data streaming. Then, you can export the data from SDI while it has stopped streaming. After export, you could continue streaming by calling "startRecording" again.

Real-Time UDP or TCP/IP protocols
You can use communication protocols such as UDP or TCP/IP to send data from the Speedgoat target computer back to the host computer while the simulation is running. The packets are transmitted over the Ethernet link between the host and target computers. The clients can be implemented in MATLAB or using external applications.
