device is simulated

[kwaris]

Hiya,

I am learning to build vi without connecting hardware. I created simulated device pc16220 in measurement and explorer. I tested signal it was white noise. I went back to labview and used examples code to locate acq&graph voltage-int.vi and inserted parameters in physical channel control and ran the vi. I obtained sine wave.

I want to check if device is simulated and can't locate deviceissimulated pallete and don't know how to perform this action. A tutorial in zone.ni.com give following info but I didn't find the route function>>ni measurement.......

( from zone.ni.com To discover during the execution of a program whether a device is simulated, use the DeviceIsSimulated property on the NI-DAQmx Device property node. Open the All Functions>>NI Measurements>>DAQmx>>DAQmx Advanced>>DAQmx System Setup subpalette to find this property node. The property returns true if the device is simulated.

 

Also in measurement explorer I only added analog voltage signal on a0 channel but in labview I get sine wave irrespective of which channel I choose in physical channel control.

Thanks for reading and thanks in advance for your help.

Thanks and Regards

Can you restate your message more clearly so we can understand what your questions are?  You posted an image that doesn't exist.  It shows up as a red X image.

I found the DeviceIsSimulated property node by following the path down the palettes that you posted.

I think you meant to say that you simulated a PCI-6220.  I don't know how you "test signal it was white noise."

Are you expecting a different waveform when you change the channel of the simulated device?  When you simulate a device, you will always get a sinewave as the signal.

If you can clearly state what you are trying to do, how it isn't working, and where you are having a problem and post a question, then it will be possible to help you better.

Thanks for reply.

Sorry for not clarifying problem.

I couldn't figure out how to confirm the simulated device by using "deviceissimulated" pallete. Also, I dont know where this pallette could be found in labview???

You've marked the question as solved but now you say you still can't find the palette? The instructions to open up the palette are correct and the property node that you are looking for is there. Can you not see the palette or the property node?
