How to overcome Error -200729 (i.e. buffer overflow) when using DAQ mx VIs

[RajKumariSharma]

Hello, NI Community,

We are facing some issues while acquiring data from NI DAQ.

We have a NI DAQ system (NI PCI-6255 and 2 boxes of BNC-2090A) in the lab for simultaneous data collection across various instruments (electromyography-EMG, force platforms etc).  We are developing the program in LabVIEW to acquire the data. In view of this, we are facing issues in the LabVIEW program, which are as follows:

Q1) How to overcome Error -200729 (i.e. buffer overflow) when using DAQ mx VIs (in continuous mode) to acquire samples from N channels simultaneously?

Q2) How can a timer be added to the code so that data acquisition happens only for the mentioned duration in the timer?

Any help is appreciated.

Thank you!

All these errors are due to incorrect usage of DAQmx APIs and inappropriate choice of architecture for the application

We can help you solve this if you can share your VI in version 16 or earlier.
