8.3.1
Data Retrieval using PreLOG-Commander (USB)
With the PreLOG-Commander the recorded data sets on the PreLOG can be retrieved directly via USB or RS232
connection for speci
fi
ed time frames and saved into a CSV
fi
le.
Implementation:
Connect the PreLOG to a PC or notebook via USB or serial interface (RS232).

115200
” Bd for USB or “
19200
” Bd for RS232 connections are selected.
Using the function “

Retrieval – Measured Values
” you can retrieve the data from the PreLOG. Select the
desired time frame and after pressing “
Request

le name for the CSV
fi
le.
The corresponding data set will be saved to a CSV
fi
le. The format can be de
fi
ned with the function “

In addition to the direct data retrieval via USB, the PreLOG can transmit the recorded data sets for speci
fi
ed time
frames via an appropriate GSM modem to a PC with PreLOG-Commander and save them as a CSV
fi
le.
Implementation:
Before you use the station it has to be con
