DAQ system crashes. (with attachement)

[enq]

I have a DAQ system that crashes frequently. So far the pattern indicates that this is caused by another piece of being turned on, but the problem is erratic. I have been unable to prove that something else is causing the problem. I have attached a Word document with the latest sequence of events.

Hello eng,

It looks like the first problem we are dealing with here is the counters locking up. Subsequent problems and errors are probably just byproducts of the original problem.

I would recommend testing your counters in MAX using the test panels to help narrow down the issue. Next I would try to run a LabVIEW example that is doing the same counter operation you are performing in your application; for example, simple event counting. Find out if the counters are still freezing.

It may also be helpful to download the latest NI-DAQ drivers available for your hardware. In your case, 6.9.3 may be helpful.


The 10401 error that you are getting later on is may be due to the main program being aborted earlier on. If the programmed stop button is not used, the �Clear� VI might not have run, and the task is not cleared out.

If these suggestions are not exactly what you were looking for or don�t help, please post the applicable portion of your code, your DAQ version, and any other information that would help track down the source of this complication. Have a great day!
