Simulink continuosly collecting data from ADS Stream - How to process data simultaneously?

Hello Mathworks-Community,

I've set up a Simulink model collecting a set of 9 data values 1000 times per second from an ADS Stream (TwinCAT3).

What I am trying to achieve now is, to simultaneously process this data in chunks (for example 10.000 rows of my output vector) to calculate forward kinematics of a robot and upload the calculated values to a MySQL-Database.

The problem I have is that I can't find a way to access the data before the simulation finished (its easy to get the simulation output as soon as the simulation is done).

As the Simulation should run in a while loop until I cancel it, I don't know how to access chunks of the data the model received from ADS Stream for further postprocessing in Matlab.

Hope you can help me with this problem.
