DAQmx Read (Analog 1D Wfm NChan NSamp).vi Error after continous long-time sampling

[pawel]

Hello All
My PCI-6025E after continous sampling (after 3 hours) reports the
following error:

DAQmx Read (Analog 1D Wfm NChan NSamp).vi<append>
Property: RelativeTo
Corresponding Value: Current Read Position

Property: Offset
Corresponding Value: 0

The same happens for DAQmx Read (Analog 2D DBL NChan NSamp).vi

I found out that it happens where the "Current Read Position" reaches
540M.
The buffer set for my PCI-6025E is about 1M. How come that the
"Current Read Postion" exceeds this number?

Can anobody tell what is going on?
Thanks in advance
Pawel

Hello

Is this post related to the one described in the link beneath?

I would like to know what error you get exactly could you mention the
error code too please. Could you desribe your settings set eventually
set in an examle that replicates your error...

I have tried to acquire 10000 samples continously with a sample rate
of 100000 and a buffer size of 1000000 without any error! It keeps the
unread samples around 300!

Hi

It is my post as well. I still work on some conclusions for the
problem.

Did you try to acquire it with DAQmx and for more than 3 hours? The
3hours seems to be a problem.
