There are two solutions to this problem. In addition, this error may occur if NI-DAQmx was recently removed, or if NI-DAQmx Base was recently upgraded. The only way to get this working as you describe is to buy two seperate DAQ boards and run each of the two AI tasks on one of them. Unplugging and re-plugging the device back into the USB port may fix this problem.

But I approach from the perspective of almost always doing hardware-timed data acq -- if there's a conflict when I make the call, it's very likely to remain throughout any reasonable Are you using Measurement Studio to develop your code? DMA is faster than IRQ and can improve performance significantly.
You can establish order of execution by wiring the Error Out terminal of one DAQ Assistant to the Error In terminal of the second DAQ Assistant. I'd think that your best bet is to use van18's semaphore suggestion. DAQmxGetErrorString doesnt work. Solution: When your system reports a USB transaction error, DAQmx aborts any tasks running on your USB device and throws Error -50808.

This could be done since the Daq reader object, stored the last acquired values in a circular buffer. The read process has a property called auto-start. click which have been resolved but not this one.
I don't know what happens if you don't request any sample timing at all, but I would read the timing from the property nodes and find out what you are getting. Because the task has reserved these resources, any task that tries to access these resources will encounter Error -50103.You can resolve this by doing one of the following: Add a DAQmx For single point or finite data acquisition the default value for the stop input is true so you do not need to wire a True Boolean constant to this input. The numbers you have posted are not DAQmx error codes that I have ever seen before.
The cDAQ-9174 and 9178 chassis have three analog input timing engines and thus can support three concurrent analog input tasks if all tasks are on separate modules.Case 7: Failing to properly Source This may be due to a fault in the system's USB host controller, a USB cable, or a USB device. Ni Daqmx Error Codes I am working with VC++ program and gives me the following error:[AI-configure] returned NI-DAQ error-10401...Again, I've been receiving several errors like nidaq32.dll not found, etc. Labview Figure 1: Device to LabVIEW Data Path To avoid an overwrite error, you need to increase the buffer size, read faster, or write slower.

For continuous acquisition, the default value is False. Once the board has acquired the specified number of samples, it will stop acquiring data.
Please tell us why. DAQmxGetErrorString doesnt work. NI Platform Services: A USB transfer failed due to a transaction error reported by the USB host controller. http://kreativexpert.com/error-code/mac-error-codes.html Case 4: Using multiple DAQ Assistant Express VIs to access channels on the same data acquisition board.Each Express VI creates a separate task, and it is not possible to have multiple
When I did something like this, I did try to use separate tasks and never got it to work. They could also request an average value from the last x samples. I know that kind of error is asserted when you try to define 2 separate hardware-timed tasks with their own sampling clocks, but I didn't realize it could also happen on
In Windows, disable, then re-enable the affected device through Windows Device Manager. To reset the drivers for Traditional NI-DAQ, open MAX and under Devices and Interfaces, right click Traditional NI-DAQ (Legacy) Devices and select Reset driver for Traditional NI-DAQ. The specified device is not a National Instruments product, the driver does not support the device. You will see your device listed under DAQmx devices, but not under Traditional NI-DAQ devices.

If there were a call which could return an immediate (non-timed) value from an analog channel, then that might work (assuming you don't care about sampling and timing, but I suspect kmagas Member 07-13-2006 12:36 PM Options Mark as New Bookmark Subscribe Subscribe to RSS Feed Highlight Print Email to a Friend Report to a Moderator Yesterday I got 15433 from DAQmxStartTask Check This Out Does anyone else have experience with or thoughts about this issue?
