NI DAQmx

I have a couple of questions.
1.) how can you input a "multiple input" signal into a subvi? I am using the DAQ assistant to aquire the signals (5 analog) then selecting them with the "signal selection" block. I want to creat a subVI that uses the Data from the the DAQ assistant, but I can not figure out how to connect the input into the sub VI.

2.) How do you graph a digitl signal.

Hi

what the DAQ assistant gives u is actually an array of data and in this case a 2 dimensional array. right click on the output of the DAQ assistand and create an indicator and you will get what i mean. if you need to connect it to a subVI, you will need to create a similar control in ur VI. mouse over the icon in your subvi to make the connection so you can wire the data from your main vi to your sub vi

Hello Scott,

What Goy said about passing data into a subVI is correct.  Let us know if you are having trouble implementing it. 

Also, to graph digital data, you should just be able to connect your digital input to a graph.  There is also a digital waveform graph on the controls palette (all controls >> graph).  If you are having trouble graphing your data, please let us know what format your digital data is in so we can give you a more specific solution!

Thanks,

Laura
