multiple simultanious measurements using daqmx

[juopa]

Hello! Has anyone managed to do multiple measurements at the same time (in the same UI) using the new daqmx-vi:s in labview 7.0? With the old traditional functions it's quite simple but with these new ones you have to do some "tricks" at least i had to?! so I would like to know if it really is that difficult, coz' i've found only one example which advices you how to do more than one measurement simultaniously. so any experience about this.. anyone??

There really aren't any tricks involved. Assuming that you've got a DAQmx Create Channel function, the physical channels input can contain a single or multiple channels. The NI-DAQmx help shows the syntax. For a range use Dev0/ai0:4 for example. For individual channels, the syntax is Dev0/ai0, Dev1/ai0:3.

Yes,so if I've understood correctly the thing is that when you want to measure for example voltage and temperature at the same time one has to place two Create Channel vi:s on the block-diagram. One for voltage and one for temperature measurement. Then wire them together and on to whatever you want to do with the measurement data. But if you want to measure say voltage from two different channels then only one Create Channel vi is needed? And you just add the physical channels from which you want your measurements?! I'm I on the rigth track now..?
