Are there any DAQmx examples available for use with pci 6229 M series card?

[Kejoglo]

I have been searching around for examples which work with the pci 6229 M series DAQ card. Most examples do not list this card as applicable and the one I have found gives an error. Is there anywhere specifically available, what I am particularly interested in is seeing an analogue channel being triggered by another analogue channel reaching a certain value.

Thanks

One way to do this would be to use the "Cont Acq&Graph Voltage-Analog SW Trigger.vi" example VI. Specify two channels for the "Physical Channel" input, the first being the triggering channel and the second being the channel to be acquired. Triggering parameters can be specified through the controls in this example.

The only other thing you might want to do is filter the triggering channel out of the data before graphing it, perhaps by indexing the array first.

Thanks I'll take a look at it.

I was also looking for more general pci 6229 examples and would have thought there should be loads around if anyone out there can point me in the right direction.

Kejoglo...

Are you using the NI Example finder? I just went to it and you can select which hardware you want to find examples for. When I select the PCI-6229 it shows several examples which that board will support.

In NI example finder if I select Dev 1: pci 6229 (NI-DAQmx) in the hardware box and tick the limit to hardware box and then go and look for vi's in say DAQmx directory. When I find an interesting vi I see that pci 6229 is NOT listed in the box headed "these devices can run this example". I therefore do not know whether they are supposed to be able to run or not. If I actually do run them sometimes they work and other times they do not. It is almost as if the pci 6229 card is newer than the examples and they have not been updated to show whether they are applicable or not.

Perhaps I am missing something?

Hi Kejoglo,

You are right in the fact that the M-Series card is newer than LabVIEW (and therefore the examples that are shipped with it) and therefore the example finder doesn't list the M-Series cards in the list of available hardware.

Basically though, the M-Series cards work with DAQmx and not Traditional DAQ so if you just go into the example finder and search under Hardware Input and Output>>DAQmx and choose an example from that folder to run on your M-Series card. As long as you don't try to do anything outside of the specifications of your card (which I doubt you will do) then you shouldn't have any trouble running any of the DAQmx examples on an M-Series card.

Hope this helps, if you still have problems then please feel free to write back.

Hello,

As mentioned, the M Series devices shipped after NI-DAQ 7.3 and LabVIEW 7.1 were released. Therefore, none of the documentation for these devices were included those version of NI-DAQ and LabVIEW. However, all M Series devices ship with an M Series Documentation CD. This CD contains all of the necessary documentation, M Series Help file, M Series information that will be added to the NI-DAQmx Help with the next release, and more. This CD also contains the .bin files needed for M series to show up in the Example Finder and instructions on how to install these.

If you do not have the documentation CD, the information is posted here: http://digital.ni.com/public.nsf/3efedde4322fef19862567740067f3cc/ec38afc6b9c2c7f386256f0a0075a79e?OpenDocument

thanks,
Nicole

Thanks to all who have responded.

I have got the additional documentation CD but had failed to realise that this also included m series examples. I'll take a look through it and try to find one where multiple analogue inputs are acquired and where one measuremnt is triggered by another one reaching a certain threshold.

Thanks again.
