Hey guys, I would be pleasure if any of you can help me! I want measure the voltages of a place, and it was working fine, but now I want to measure the temperature from the room too.. and that's my problem.When I put 2 DAQ virtual channels it won't work, I receive an error when I tryed to read the Voltage and the Temperature. Error -50103 occurred at DAQmx Read (Analog 1D Wfm NChan NSamp).vi:1 Possible reason(s):The specified resource is reserved. The operation could not be completed as specified.Task Name: _unnamedTask<17C> If I click on continue, I receive the same error again and again and again...Can any one help me on that? How can I measure more than one thing with DAQ MX?Because if I measure only one thing it works, but when I try 2 or more it crash. I will upload the vi's and one image with the code! Thanks

You would do something like this. I really don't remember if the data is sorted by column or rows when you return a 2D array. This is for the temp data in the last column. If it's sorted by rows, then wire the '7' into the row input of the Index Array. Or, move the Index Array to before the Transpose Array. You may want to use the Delete From Array function to remove the temp data before you pass it to the for loop. That's up to you. The for loop you have is also constructed badly. Make use of the Auto-Index feature of a for loop and you don't need to wire up the for loop's 'N' terminal and can eliminate the Index Array function inside the for loop. Spend some time and take the LabVIEW tutorials and look at the shipping examples to get an idea of how for loops work and options for Indexing Arrays.
