Constant Analog Output Voltage

[Chady]

I am trying to run a motor  using my PC so i need to assign a Constant analog output voltage. How can i do that in Labview 8.0? I have an M series DAQboard so i can't use any traditional blocks, it has to be express Vi's or DAQmx.

You can use the DAQmx Write with it set up as Analog Output/Single Channel/Single Sample/DBL and just write the value out.

Hi Chady,

you can use this VI(DAQmx)

That Vi you sent, will only send a pulse voltage, but i need it to be a constant like a step voltage.

I think it did that because he clears the task at the end.  Try this modification of that vi.  I added a loop that will keep the vi going until you hit the stop button.  Then the task will clear.

As randall has shown, putting the DAQmx write inside the while loop will do the job
