  1. Hello all, My question is: what is your preferred non-volatile way of storing daqmx task configurations? Backstory: For a long time I've used ini files to maintain task configurations between executions of a program. This has worked for primarily static DAQmx configurations but I'm looking at creating a test executive with some degree of flexibility, which means daqmx task configurations start to get more complicated. If you use MAX for storing your tasks: Do you run into problems accessing and maintaining these tasks even though you don't have direct access to the file? Or is there an unlisted storage location for these files? If you use ini/text based files: How do you keep things orderly? I'm running into all kinds of limitations with the format. If you use XML: Where did you find your schema? Did you write it? I know NI saves tasks as XML files, and so therefore the schema exists, but I haven't been able to figure out how to use it. I've created a task in my project and then dug through the XML of the project to find the attached image. I believe this would be the ideal solution, but a little bit of digging in around NI.com (I know...) and google (actually useful) has resulted in no answers. I know there is an elegant answer to this question, I've just not found it yet. Thanks in advance for your comments. Cheers, Tim M
  2. I have a problem I was hoping you might be able to help me figure out. I need to be able to create 6 analog output channels that will have separate data files loaded into them. These channels will be started individually in a timed sequence. I am having trouble getting the analog DAQ tasks created. LabVIEW is complaining when I try to set them up as individual tasks in the same routine. I used a for loop on an array of data files and an array of channel names. The error code is suggesting that I set the channels up under one task. But the problem with that is that I don’t know how to get individual channels of that one task started. I created the initial for loop in Main.vi. This gives me error -50103. My single instance is in Main_1.vi. I am trying to use a PXI-6363 card initially because that is all I have now. But I will try to upgrade to a PXI-6733 when I get ready for the test. Is there something with the 6363 that doesn't allow for multiple tasks on the same card for the same function? Thanks for your help. Joe Main.vi Main_1.vi
  3. When trying out a new program most error messages that LabVIEW gives me are not very helpful because they refer to "unnamed task" such and such. And so I would like to give names to my tasks. It ought to be simple but still it illudes me. So now I ask... How do I give a name to a task so that error messages then will be helpful?
