Fieldbus Alarm Messages

Alarm messages are usually transparent to the user. A host system typically receives these messages and presents them to the user. Acknowl-
edgment of alarms by the operator may be necessary to satisfy operation requirements.

Event Messages

Event messages contain a time stamp

Events also must be confirmed; otherwise the block will continually report the event.

Acknowledgment of events may be necessary to satisfy operation requirements
