– 1: (Default setting) Log entries are only written to the CompactFlash card if the internal
buffer is full. If the control system is switched off, entries in the internal buffer may be
lost.
If a PLC crash signal is output or the action log is activated/deactivated, the entries
are always saved.
– 0: These log entries are stored consecutively on the CompactFlash card. This can

– >0: Time (in seconds), after which the internal buffer is written to the CompactFlash
card.
