Since you failed to provide us any information on what you were trying to do, nor provide any code (files with the extension .vi -- please, no "pictures" of Block Diagrams or Front Panels), we can only tell you how to find out for yourself.
Open LabVIEW. Click "Help". Click "Explain Error". Put the number -200279 (don't forget the "-" sign) in the Code box. Read the explanation:
Error -200279 occurred at an unidentified location
Possible reason(s):
The application is not able to keep up with the hardware acquisition.
Increasing the buffer size, reading the data more frequently, or specifying a fixed number of samples to read instead of reading all available samples might correct the problem.
If you have been using the Error Line properly, you may have additional information, such as the VI that was running when the Error occurred. Use this information to fix your code.
