usb6008 DAQ connection error

[dadsf]

currently i need to aquire voltage signal from accelerometer through USB NI 6008 DAQ. i have created DAQ assistant in my VI. but when i click run, there is error occur. so can anyone please help me to identify my error. thanks

Hi,

The error that you are seeing (-50103) is one of the most common DAQ errors.  Take a look at this KnowledgeBase article, which explains the possible causes for this error.  Case 6 is what you are seeing.  You have two DAQ Assitants and are concurrently running two AI tasks.  Consolidate to one task and acquire on multiple channels in the task if you want to.

hi, thanks for the advice. i have make some changes on it. but now im facing problem cause i got 2 voltage signal from the accelerometer, each represent one axis. but the problem is how should i design my VI so that i can detected both signal at the same time. below is MY VI design.

You've got a lot of redundant code and you need a while loop to continously acquire (do NOT use the run continuous button), but it is setup to read from both channels at the same time. What you are not doing is splitting the dynamic data into 2 different channels. Out of the DAQ Assistant, use the Split Signal function.

hi guys, i would like to ask how should i design my VI so when my analog port of USB6008 received 1V then my digital port will give out digital output for example in 4 bits 0001. then when the DAQ received 1.5V digital port wil give out 0010 for example.

Use comparison function to compare value, and wire boolean output to case structure, and outpput array of boolean in each case. This method would work on every value you wish to compare.

hi there. do u have any sample for me to refer to. cause im still new in LabVIEW so i can't really get what you mean. hope u can help me. thanks
