I'm not sure I can give you an example because I still don't understand what you are trying to accomplish. Your initial VI has 3 DAQ Assistants and each are taking 100 samples of analog data. You then wired them up to Booleans. Exactly what type of measurement are you trying to take? What are the signals you have connected to the DAQ board? Are they really analog signals or could you use the digital I/O on the DAQ board?
If you are using the DAQ Assistant to read 3 separate analog inputs, then you can use the split signal function to separate them out. If it's DC level that you are reading, you probably don't need to take 100 samples unless you need to do some averaging. If you want to compare the signal to some threshold, then use the comparison functions. Do not wire directly to some Boolean.

Hello.
I am trying to design a Voltmeter with different input channels on LabView 2013 with a USB 6009.
What I need is the voltmeter to be capable of reading voltage (supplied by a function generator) from three different channels at the same time, I used three DAQ assistants for this purpose.
When I hit the "Run" button on front panel, the Voltmeter only can read one value at a time, while on the "Error out" icon appears the error code -50103.
Is it possible to read three different voltage values of three different input channels at the same time?
Thank you for your support...
