Data log/USB

Parameters
48
Data log uses 2KB of backup SRAM (under battery) for data records.
Interval for storing records is 3 hours. State change to fail mode also invokes record store.
If whole space filled by record then new one will replace the oldest.
After connecting USB flash drive all collected records will be stored to file data_log.csv in CSV
format. Records won't be deleted from board so it is possible to get data onto several USB drives.
