Overview of the Data Structure

The SMA Fuel Save Controller records the system history and saves three files with different data each day:
• One file with data for fast acquisition of measured values
• One file with data for slow acquisition of measured values
• One file with event and error messages
Once the SMA Fuel Save Controller has recorded the system history for 100 days in a ring buffer, it starts to overwrite
the files.
The files are saved in CSV format and recorded according to the following pattern:
File content Name structure
Data for fast acquisi- LogDataFast_JJJJ-MM-
tion of measured val- TT.csv
ues
Data for slow acquisi- LogDataSlow_JJJJ-MM-
tion of measured val- TT.csv
ues
Event and error mes- ErrEvtLog_JJJJ-MM-TT.csv
