The ExportData step saves recorded values of a RecordData or PlayData step into a file.
Two output file formats are available:
· LVM—Dedicated to numeric values, useful for saving waveforms
· TXT—ASCII file with separator (Tabulation, Comma, Semicolon)
· TDMS—Binary file with property (Test Data Exchange Stream)
It is possible to specify a Suffix, which will be appended to the file name generated by ExportData step.

Note The format specified for each channel within RecordData step is used for formatting numeric values into TXT file. |

Note The TXT file created by ExportData step is compliant with PlayData expected file format, when source is configured data from file. |

Warning The time information for TDMS and LVM file format are not relevant. Sampling period, dt, is always 1, and start time, t0, is always 0 (interpreted as 01/01/1904 00:00:00.000). If time information is important, it is recommended to add a time Item in RecordData Configuration. |
Decimal Separator
· For LVM files, the decimal separator used when creating the file is determined by the system configuration. The decimal separator is specified in LVM file header, so the generated files are system configuration independent.
· For TXT files, numeric values are formatted using period as decimal separator.
