After clicking the “
Request
” button you can select the directory and the
fi
le name to save the recorded data. The
PreLOG-Commander checks if the connected station is identical with the selected con
fi
gurations. A message
box will inform you, if there are differences in the con
fi
guration. In that case the function “
Measured Values
” will
be cancelled, so you are able to correct the con
fi
guration with the aid of the functions “
Setup – Select Current
Station
” and “
Setup – PreLOG Con
fi
guration
” (see ch. 9.2.2, pp. 20 ff.).
If the con
fi
guration is correct, the PreLOG-Commander will start to retrieve and save the data. The progress as
well as the end of retrieval will be displayed in the “
Info
” area. The selected
fi
le name including the complete path
is displayed in the
fi
eld “

”. After the data transfer has been
fi
nished, the duration of the data transfer as well
as the number of transferred measured values is displayed in the bottom left corner.
The data of each retrieval are saved to a separate CSV
fi
le. For further information regarding the CSV
