Info
Users have the flexibility to designate alarm alerts as either warnings or excursions. Warnings are typically used to receive a notification when a condition is trending out of spec, but has not reached a critical point. Excursions are typically used to alert the user when the condition has reached a critical point. All warning and excursion events will be documented in the system. However, only excursions will display a flag on the graph and appear on export and reports. Warnings will not.
