I have a chemical process with several variables (pressure, temperature, concentration, etc.)
In Simulink, the only way to have access to the values of the variables (pressure, temperature, setpoint) is the workspace. But I should wait until the end of the run ( for example 1 hours) to get access to the values of these variables from the workspace. I would like to get the values in real-time and use them in another application.
I hope that I explained my problem better than before.
This doesn't exactly allow you access to your data in real-time, but you can use a Data Access callback function to access packets of data for a logged signal during the simulation. You write the code for the callback function in an m-file and then specify the function name and inputs the function expects in the Instrumentation Properties for the signal. After you mark a signal for logging, you can access the instrumentation properties by right-clicking the logging badge and selecting Properties.
You can use the same callback function for multiple signals, or specify a unique callback function for each logged signal.
