Mulitple Ai - Error 200284

[Kyle W]

I'm trying to run two programs at once via USB-6009 to get readings of a tachometer and LVDT. When I run the two programs I get the following error # 200284. I understand this has to do a timeout problem. I have tried changing this from 10 to -1 (to wait indefinetly) however I keep getting the same error message. Is there something else I need to change or anything else I can try?

I hope it helps.

Thanks, I read that before, the '-1' change it mentioned doesn't get rid of this problem rather makes it occur more quickly.

Are you running two spereate analog input programs on the same device at the same time? If this is the case, the second one will generate an error. You set up one task with the same timing and read both channels at the same time. Just specify a range of channels Dev1/ai0:1

If this is not the case, maybe you can attach your VI.

Hello,

i have the same problem with the attached vi. Some times i get the following error:

-200284

DAQmx Read (Analog 2D DBL NChan NSamp).vi:1<append>

<B>Zugehöriger Wert: </B>Aktuelle Leseposition

Have somebody a solution?

Hi Schwede,

It might be worth posting this on a new thread (you can always referance this thread) as then our German branch will be informed and they might be able to help (our German is not very good here!)
