3.6.3 Configuring the alarm log
Logging
Configure the alarm log in the "Diagnostics" operating area.
All alarms and messages are logged in chronological order with their raised and cleared time
stamps. The exception are messages of the type "msg" from the NC part program. All alarms
and messages that are no longer active when the log is displayed are also retained (historical
alarm events).
The alarm log is organized as a ring buffer (default setting). The oldest entries are overwritten
with new events in the following cases:
● When the maximum size is exceeded (permissible range: 0 - 32000).
● When the events happened before the last time the system was switched on.
Permanent backup
Default setting: The alarm log is not backed up.
A backup of the alarm log is written to the card/user/sinumerik/hmi/log/alarm_log
directory on the CompactFlash card. Set up a filter to limit the number of events in the alarm
log and select a range:
● Time interval
● Alarm number range
