Step 5. Set Global Alarm Settings

You can choose to store runtime alarm comments that a user enters while the alarm is being displayed in the Alarm Viewer. Normally, these comments are deleted when the alarm is deleted. CIMPLICITY saves the 20 most recent alarm comments in a file in the project's alarm_help directory.

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.
