X-Series USB-6356 and Simulink Real-Time Windows Target

[gimarkus]

Hello everybody,

I've been successfully using the NI USB X Series 6356 board to aquire data for several months, now I need to close a control loop via Simulink.

Since our application is rather fast and requires a sample rate of about 10kHz, I was planning to use the Matlab Real-Time Windows Target Toolbox or the xPC toolbox for control.

Unfortunately, I discovered that the X-Series 6356 board is not supported bei either of these two toolboxes. Only Mathworks' DAQ toolbox supports this board -  but at the same time it is not suitable for code generation.

My question is: is there any way to make the X Series 6356 board compatible to either xPC toolbox or Real-Time Windows target?

Or is our board maybe even the wrong instrument for fast control loops?

Why is the X Series 6356 board not supported at all with Real-Time Windows Target or xPC?

We´re using Win7 64bit, Matlab R2013a 32bit.

Any help is appreciated! Thanks.

I tihnk MATLAB building DAQmx toolbox based on NI-DAQmx which is why it's ok on Windows. NI have their own RT system based on Pharlap which is different from MATLAB RT. That's why it's not compatible.

Hi,

basically the USB-6356 needs the device driver NI-DAQmx. The driver ships the API so you are able from different programming languages LabVIEW; C; C++ communicate with the USB device.

Unfortunately I couldn't inform you how Mathworks build up/implement the driver finally in their toolbox.

I would recommend to ask Mathworks for the driver support in different toolboxes.

Kind regards,

Thank you, I'm going to contact Mathworks directly!
