Controlling Analog Output in *.vi

[bronco9588]

Hi Y'all,

I have a PCI-6281 with an SCB-68 B.O.B. Anyways, I have been using the two analog output channels to drive some voltages across some instruments. Everytime I reboot the computer, I have to reset the voltages using the measurements and automization explorer. (I go to measurements and automization explorer > Devices and interfaces > NI PCI-6281 dev 1 > test pannels... > analog output). Is there a way to have the VI set this everytime I run it? THX

Your question does not make much sense. If you already have a VI, then you are controlling the analog output so I am not at all sure what more you are asking for.

I would like to set AO 0 to 1.5 volts and AO 1 to 5 volts. I have to do this through Measurements and Automation explorer. When I reboot, I loose those settings and have to repeat. Is there a way to get the VI to set this.

Start by searching for examples of analog output or analog generation.  The examples which come with LabVIEW are a good place to start, a good way to learn how to use the DAQ drivers, and may be all you need for simple applications.

Look at the DAQmx Write.vi in the DAQmx pallet.  Also look up in the example finder (Help->Find Examples...) for DAQmx Analog Output.  There should be plenty of examples that you should be able to strip down to simply set the voltages.

The examples are a great little resource.
