” sets the period (in seconds) of the timed interval reports to the EEPROM
and RAM for booting and immediate use. For example, the command “
LPS0000000360x
” sets the reporting time to once
every 360 seconds.
Executing the command “
LPM##########x
” sets the period (in minutes) of the timed interval reports to the EEPROM
and RAM for booting and immediate use. For example, the command “
LPS0000000005x
” sets the reporting time to once
every 5 minutes.
Logging threshold setting for interval reporting Executing the command “
LT########.##x
” sets the threshold of the
timed interval reports to EEPROM and RAM for boot and immediate use.
The units are
