Hi Bharath,

right click on the connector and select "create constant".

Hey mike,

That's a simple and efficient practice of programming. Thanks for the tip.

Thanks,

Mathan

Hi Mathan and Mike,
 
I have tried with the double precision constant. But, the waveform is not the continuous one.
Can you please check the following attachment and tell me the reason.
My version of labview is 8.0
Thanks,
Bharath

Hi Bharath,

what does it mean? Do you need something like the attachment?

Hope it helps.

Thanks Mike,
            Now it is working..I did not place the loops properly.
            Thanks for your assistance
Bharath.

HI mike.,
 
      For the analog waveform generation by using DAQ, i am interfacing the waveform block with DAQ.,it is giving error like 'sub DAQ mx write:iput/channels in is not wired' for the analog waveform.
     For this particular case what may be the virtual channel/??where do i connect that?or else i have to create it by other means?
    
                  When iam executing the example "Cont Gen Voltage Wfm-Int Cll-On-Board Regeneration",it is giving continuous analog waveform by using the   PCI-6024E/BNC-2120 combination.I am using that example refering to my problem.
                 I am attaching the VI of the problem.Thanks for the help.
Bharath.

Hi Bharath,

use the example finder to learn more about DAQmx, there are good examples. Cna you please explain what you try with this example?

Hi Bharath,

i think this could be what you need. Hope it helps.

Hi mike,
          I need the analog output for one of my algorithm's input.I have to generate the waveform continuously with the values.
         The VI that you have send is running but not showing the analog output when iam taking it from the analog outputd DAC-0 on the BNC-2120.
       
         I am verifying it on oscilloscope.But it is not showing any thing.
         And also my values are in the range of 350 to -350.so we need to change the max and min values.Can we do that?

 Thanks&Regards,
 Bharath

Hi Bharath,

change to AO - voltage on the create channel vi.
You can change the min and max values, but not to 350. The 5 and -5 are voltages, and i know no card which can output 350V.

Hope it helps.
