Error -200220

[tanju]

G'day

I have a NU iSB 6259 connected to a power amplifier and shaker through AO0. I have downloaded the swept sine VI from the NI website to go with the sound and vibration toolkit.

However when I run this VI even though I have slected my A0 excitation channel : Dev1/ao0 the program shoots out the error message: 

Error -200220 occurred at SVT Initialize Swept Sine (DAQmx).vi

Possible reason(s):

Device identifier is invalid.

I havent connected any input devices as I am waiting for them to come in the mail however I really was hoping to get the swept sine VI working and the FRF to atleast ouput zero as Its not measuring anything as yet. I have not connected tthe AI stimulus or response channels to anything on the device either.

Just hoping to get the shaker moving at the moment at the frequencies designated

Your help is most appreciated

Code?  It is really hard to diagnose your problem without it.

Hi crossrulz,

please find attached the screen shot errors I am having, Is this what you are asking for I am new to Labview not sure how to generate the code or if you just meant the graphical programming.

The block diagram is your code.  It's generally better to post your VI.

This is also my measurement and automation explorer

Your AI Stimulus and AI Response channels are both blank/empty on the user interface - the code is probably trying to connect to the hardware and it isn't a valid DAQ resource hence you are getting the error.

I have the same program running on labview 8 and run it with empty channels and it runs fine. However another person is using that system and I need to setup my own one and I keep encountering this error anybody have a solution?

your help is most appreciated

Tanju,

If I understand you Don't have the hardware yet?...

If not, you can create a "Simulated" Device in MAX. Then your LabVIEW code will 'connect' and acquire data from the simulated device - allowing you to test your code.

It works quite well. Goto MAX and create the simulated device, when you're done, Refresh your DAQmx device list in LabVIEW and you should 'see' the simulated hardware.

Your code should then work... (provide youn coded it right!;).

It will also work when you do get the hardware - be aware you need to then select the actual device and not the simulated one!.
