Data Amount
and Memory Ca-
pacity
One USB thumb drive with a memory capacity of 1 GB, for example, can record
logging data at a logging interval of 5 minutes for approx. 7 years.
CSV file
CSV files can store only 65,535 rows (data records) (up to Microsoft® Excel ver-
sion 2007, afterwards there is no limit).
At a logging interval of 5 minutes, the 65,535 rows are written within approx. 7
months (CSV data size of approx. 8 MB).
To avoid a loss of data, the CSV file should be backed up to a PC within these
7 months and deleted from the USB thumb drive. If the logging interval is set
longer, this time frame is extended accordingly.
FLD file
The FLD file should not be larger than 16 MB. At a logging interval of 5 minutes,
this corresponds to a storage duration of approx. 6 years.
If the file exceeds this 16 MB limit, it should be backed up to a PC, and all data
should be deleted from the USB thumb drive.
After you have backed up the data and removed it from the USB thumb drive,
the thumb drive should be immediately reinserted so that it can record logging
data; no further steps are required.
Notice! A full USB thumb drive can lead to loss of data or overwriting of data.
When inserting the USB thumb drive, make sure that it has a sufficient memory
capacity.
