DAQmx Stop Task error -50550

[Glyn]

Hi,

I'm occasionally encountering error -50550 while attempting to stop an AI Task; though its occurrence is sporadic:

LabVIEW Error Details:
Error Code: -50550
Source: DAQmx Stop Task.vi:3 Task Name: AllAI
Description: Error -50550 occurred at DAQmx Stop Task.vi:3 Possible reason(s): A synchronization object was not acquired within the time limit. The operation could not be completed as specified. Task Name: AllAI

The way I've currently written my VI, I'm creating an AI voltage task with a sampling rate of 1k and buffer size of 50k. I start the task use the daqmx read in a while loop until I reach a threshold, and then fall out of the loop and stop the task.

I'm using LabVIEW 8, DAQmx 8 on WinXP.

Anyone have any idea of the cause or cure?

Thanks in advance,

Glyn

Hi Glyn,

Unfortunately, I do not have many ideas about that error.  Can you post the portion of your code that demonstrates this error so that I can try to see it?  Also, how often do you see this error?  It sounds like it is not every time that you run the program.

Thanks,

Laura
