Configuring alarms

Never creating new files
Click Never. Logged data is added to a single file.
To manage disk space if a log file grows too large, stop alarm
monitoring, delete the alarm log file, and then restart alarm
monitoring. You cannot delete an alarm log file while RSView32 is
monitoring alarms. For details about how to monitor disk space, see
“Monitoring disk space” on page 18-14.
Deleting log files
You can delete log files after a specified period or once a specified
number of files has been created. If you never want files deleted, leave
the check boxes under Delete Oldest Files blank.
Alarm log files are deleted only when a new file is created. So, if your
project creates a new file each day and deletes the oldest file every
third day, your project will have files for the three previous days’ data
as well as a file for the current day.
