Measured value transmission to the control inputs of the inverter
All recorded measured values, operating messages and alarms are made available via the CAN bus
and the BMS bus. Communication is primarily carried out via the CAN bus.

History memory
All warnings, alarms and device errors including "Come", "Go" and "Acknowledgement" timestamps
are stored in the internal history memory.
The history data are copied from the internal EEPROM to the History.csv file on the μSD card under
the following conditions:
- following device start-up
- during operation once an hour
- when a compatible μSD card has been inserted
For the evaluation of the history memory, the Excel tool "iso1685 History.xlsx" can be made available.
This tool allows csv.-file data to be processed and evaluated. By way of example, history memory en-
tries are shown on page 48.
The tool includes detailed information about the use.
