Use front panel data logging to record the values of controls and indicators on the front panel to a datalog file. Enable front panel data logging interactively or programmatically.

Each time a VI runs, front panel data logging saves the front panel data to a separate datalog file, which is in binary format. You can retrieve the data in the following ways:

  • Use the same VI from which you recorded the data to retrieve the data interactively.
  • Use the VI as a subVI to retrieve the data programmatically.
  • Use the File I/O datalog VIs and functions to retrieve the data.

Each VI maintains a log file binding that records the location of the datalog file where LabVIEW maintains the logged front panel data. Log file binding is the association between a VI and the datalog file to which you log the VI data.

Note LabVIEW does not support front panel data logging through remote panels.
