Sumathi, P. Use the LabVIEW error handling VIs, functions, and parameters to manage errors. For example, when I write a command to a GPIB instrument and I don't get any value back, I receive a timeout error (-1073807339) that breaks my loop. this content Wire the error information from the beginning of the VI to the end.
When you perform any kind of input and output (I/O), consider the possibility that errors might occur. Labview Error -1073807339 Visa Read If so, do you have a CAR#? Thanks in advance Framing Erors are generally due to issue with the transmission medium.
