Clear Task Error

[vedran]

Hi,

i use DAQmx Create Channel.vi's to create 3 Channels: one of them as differential- so i have 2 (later maybe 3) tasks. Problem is, when i start my VI, i get error how some task resources are reserved, but i use Clear task?!?

Here is my application.

p.s.: Why not DAQmx Assistent Express? Because i need to change the sampling rate online.

Thanx in advance

Dear vedran,

You have to combine measurements of the same type into one task.

To understand better please have a look at the following links:

I slightly modified your VI (attached). Now it should work but with your card you're not able to change the sample rate of these measurements seperatly.


Best regards
