Multiple Picoscope 5442B in Labview Application

[zwfjames]

Dear all,

I am trying to use 3 picoscope 5442B with Labview to collect 12 channels of data at the same time. I am using streaming mode. At first, I can run the single-picoscope in my program very well. However, When I copied another call function in the labview, I get all 0 values from the second picoscope, while the first one works fine. It is not a hardware problem. The single-picoscope labview program works fine on each picos separately. Can anyone look into my code and see anything wrong? Thank you very much.

To see the subVIs in the program you need the .llb file in the same folder.

I am assuming that the dll will allow simultaneous calls to it ie you are not limited to just one piece of hardware per dll?  Maybe try coping the dll and renaming it then specify a different Path on the Call Library Function Node.

Does the PicoScope5000aOpen.vi error out for the second hardware?  How are you pointing to the second Pico? (it looks like you have a SN option, otherwise all the Open.vi point to the same Handle = 0).
