How to generate PWM signal with VeriStand, Simulink and PXIe

[kmerr]

I am using NI VeriStand with Matlab/Simulink.  I would like to generate a PWM signal out from a PXIe-6358.  Does this occur through the digital out or the Counter channel?  How is this accomplished?

Does the PXIe-6358 have PWM generation capability built into the hardware or do I need to program the PWM in Simulink?

We want to use Simulink and not Labview.

Any help would be greatly appreciated.

Best Regards,

Hi Kyle,

According to this documentation, it looks like PWM is not natively supported for DAQ cards in Veristand 2010.  You can build a custom device to accomplish this, however this would need to be built in LabVIEW.   If you want to use Simulink,  you'll want to build a model that interacts with the hardware and outputs PWM.    You can then import this model into VeriStand and run it.    Here are some good articles that will help you get started:

Hope this helps!

I wanted a Labview based model for veristand which can generate pwm signal, can you please help me in that

Hey Akshat,

What hardware are you using? Only certain NI hardware is capable of producing a PWM output so we first need to verify that we are able to do so with your hardware configuration.
