Run Simulink continuously with NI-DAQ

Hi,
I need to run the acquisition by DAQ continuously with external analog input.
I tried with Analog Input block from Data Acquisition Toolbox (it finds DAQ automatically and allows to set Sample rate, channels, etc...), but at stop time, obviously, acquisition turns off.
In Real-time windows target (analog input block), if i check among Data Acquisition Board there's not my DAQ (NI-6020E).
How can i make it acquire signals by DAQ?

If the Data Acquistion Toolbox is fast enough for you, you can set the stop time to Inf, and it'll keep going until you manually stop it.
HTH,
Arnaud

Ok. Therefore is a scope options. So, without scope, can i say that data flows fully during simulation?

Yes, it should do, unless you run out of memory or the buffer gets full. I imagine that the data coming from the DAQ card fills up a buffer which gets read by the software.

For use with Real-Time Windows Target, you can only use boards that are in the Supported Hardware List.
If you don't see your device here, you can submit an enhancement request with Tech Support so your board can be considered for support in a future version of the software.
