Failure during a data acquisition
In a test run I have to acquire continuously 14 channels with 20k Samples/sec by LabVIEW 8.0. The channels are declared in DAQMx and defined in relation to a task. 7 channels in a task for the PCI-MIO-16E and the USB Device 6015. This tasks are opened in LabVIEW and the data acquisition starts. There is a buffer containing 10k Samples/sec. Furthermore 2 files are created, the one for the data of the PCI-MIO and the other for the USB_Device. The data is written into two different files in the TDM file typ. If the VI stopps, the memory for this files will be closed again. After about 45-50 minutes of run there is the failure (see picture). The size of one file is approximately 4,5 GB. The harddisk drive is NTFS-formated.
Short translation of the failure message:
VI is stopped at joint 0x0 of the internal LabView SubVI "_saveFloat64Channel.vi"
enclosed please find the block diagram of the data logging VI.
Thanks for your reply!
