I cannot create more than 1 DAQ Assistant to acquire signals from Compact DAQ

[djeison]

I am using CompactDAQ hardware to acquire and produce several analog and digital signals to control laboratory equipment.I have realized that when programming in Labview I cannot create more than 1 DAQ Assistant to acquire signals in the program. I can put as many DAQ Assistant icons to generate signals, but only one to acquire signals; otherwise I get an error indicating that modules cannot be accessed. Attached is an image of part of my program where you can see that I have used only one DAQ Assistant to acquire all the signals.Is this normal? Thanks in Advance David

It is normal to only have a single assistant for either analog acquisition or analog generation. When you have single A/D or D/A clock that is shared, you must combine all acquisition into a single task with multiple channels and generation into another single task. With software timed digital I/O, you can use multiple tasks.
