Thread Subject: DAQ Timeout

Hi there, I am running the following code using a NI
PXI-6713 analog output card:

a0 = analogoutput('nidaq','PXI1Slot2');
addchannel(a0,1);
addchannel(a0,0);
set(a0,'SampleRate',1000);
set(a0,'TriggerType','Manual');
data = a*ones(10,1);
data2 = b*ones(10,1);
putdata(a0,[data data2]);
start(a0);
trigger(a0);

I execute this for different values of a and b in a loop
changing from one to the other every 2 seconds using pause(2);

However after about ~170 iterations I get the following error:
??? NIDAQmx error : The specified resource is reserved. The
operation
could not be
completed as specified. Task Name: MWDAT0528 Status Code:
-50103

Error in ==> dc_test at 25
start(a0);

I probably need to put some wait handle or something because
I guess I am not buffering properly or something of the likes.
Anyone know what I might be doing wrong ?

Thanks,
Jason

You probably want a
wait(a0,2);

somewhere that will ensure that the output is complete
before attempting another one.

Oh -- what version of MATLAB and Data Acquisition Toolbox?

I did have a wait(a0,10) in there but commented it out,
still times out.
Any other point to note ?
Matlab Verssion 7.5
DAQ Version 2.11

Matlab 7.5
DAQ 2.11

Had wait(a0,10) in there before but commented it out because
it made no difference, i.e. communication still lost to NI DAQ

Do you have Traditional NI-DAQ installed? Typically, when
we see this message, it's related to that.

If you mean by Traditional NI DAQMx or whatever it is
called, then yes I do. But if i remove that software then
obviously matlab doesnt recognize my NI card anymore!
Yesterday i got this error about every 30 minutes, and I was
writing new outputs every say 10 seconds.
Very wierd..

Hi Jason,
NI-DAQ comes in two versions.
Traditional NI-DAQ and NI-DAQmx.
You can see what you have installed in NI's Measurement and
automation explorer. Click on Help->System Information
Once you know what you have (one or the other, or both)
please see these links:
http://www.mathworks.com/support/bugreports/details.html?product=DA&rp=284483
http://www.mathworks.com/access/helpdesk/help/toolbox/daq/f5-54913.html

If you need to repost, could you include the NI section of
the output of the command DAQSUPPORT?
That may give more insight.

Hi Jason,
Thanks for including the DAQSUPPORT. It does not show
anything glaringly wrong.

Have you ever run this program in a release prior to R2007b?
If yes, did it run correctly?
If no, is there any way you could easily try R2007a or R2006b?

Also, I see you only have 1 device on this PC, but if you
have other PC's with other devices and know if it happens
with other devices I'd be interested to know that too.

Ive tried it with R2007a. Same problem. Basically if I
change the voltage on my outputs (as outlined in the initial
post) after about 30 minutes I get the timeout error. It is
very weird because I dont think that I'm doing anything
wrong, it seems more to be a bug of some sort.
Thanks,
Jason
