13.3 Configuring an alarm log
Default
Per default, the alarm log contains all alarms and messages - with their incoming and
outgoing time stamps - in chronological order since the last boot. The exceptions are
messages from the NC part program (msg command).
Contrary to the "Alarm List" or "Messages" window, all of the alarms or messages that are no
longer active when the log is displayed are also displayed (historical alarm events).
Specify the number of results
The alarm log is organized as a ring buffer: When the maximum size is exceeded, the oldest
entries are overwritten by the new alarm events. Each incoming or outgoing time stamp
represents a separate event.
Persistent storage (permanent storage)
If required, the alarm log can be set up as a persistent log that also contains alarm events
from before the last time it was switched on. This means that the log is then either time
controlled or for each alarm event, is backed-up in an internal binary format in the file
system.
Depending on the hardware being used, for the NCU, the alarm log is saved on the
CompactFlash card or for the PC/PCU, on the hard disk.
Note
If the alarm log is written to the CompactFlash card for persistent storage, then only a limited
number of write cycles is possible. Therefore, ensure that the storage is only performed
when there is a justifiable need!
The alarm log is not saved in the default configuration.
