Data amount and
memory capacity
One USB stick with a memory capacity of 128 MB, for example, can record logging data at
a logging interval of 5 minutes for approx. 7 years.
CSV file
CSV files can store only 65535 rows (data records) (up to Microsoft® Excel version 2007,
afterwards there is no limit).
At a logging interval of 5 minutes, the 65536 rows are written within approx. 7 months (CSV
data size of approx. 8 MB).
To avoid loss of data, the CSV file should be backed up to a PC within these 7 months and
deleted from the USB stick. If the logging interval is set longer, this time frame is extended
accordingly.
