Error 50103 LabVIEW

[hector_rosas]

Hi my name is Hector Rosas and im using LabVIEW 2011. The reason im here is because im making a project and i got a problem. In this project im running some subVI's using 2 AI and when i try to run the program it shows this error:

 

Error -50103 Ocurred at DAQmx Start Task.vi:8

 

Possible reason(s):

NI Platform Services:  The specified resource is reserved. The operation could not be completed as specified.

 

why did i get this error? i've read in some other posts and they say its because im running two task at the same time and my DAQ cant do it. Im using a USB X Serie (USB-6341) cant i do this using this DAQ?

 

Thanks!

You'll want to read both channels in a single task and then split the data to your required VI's

 

This is a good, simple example.

Here are some other good DAQ related tutorials!

You may try looking at some design patterns. I would start by acquiring data in one loop while doing work with that data in a second loop.

If you do some digging, you will find that many more Design Patterns on NI's website.

 

If you this still doesn't answer your question, post some code!

 

Good Luck!

MCornwall is right (and has some great links). The X Series do have some additional timing engines now vs the older cards but because they are still typically multiplexed cards the ADC is already in use and cannot be used twice.

hello guys

I have 2 input channels in my VI and I'm getting the same error because of running 2 tasks at the same time. I know a solution for that could be to combine all channels into one task but this solution wont work for me and I need these 2 channels to run in 2 separate tasks because I need  to use different trigerring for each input signal and if I combine them into one task it is not possible anymore.

Is there any way I can keep them running in separate tasks and also get rid of that 50103 error?

 

I'm using a PXIe-6124 (S series) DAQ device..

 

FYI: I'm really new to the labview..
