Guidelines for storing alarm comments
- Each comment can contain up to 720 characters.
- Up to 20 comments are stored in an alarm comment file. When the 21st comment is placed in the file, the first (oldest) comment is removed.
- If you intend to enable the Store alarm comments option, make sure that the
alarm_help
directory is writable. - If you want a comment to be associated permanently with an alarm, put it in the alarm's help file.
