9.10.3 Event Notifi cation
When a setting change and a change of the Self-
diagnostics occur, device detect it as an event and
can transmit an alarm signal continuously.
Alarm contained in the following item can be set to
Event, and can be detected.
• Device Status
• Status group 1 to 3
• Ext dev status
• Device diagnostic status 0
Up to four events that occurred can be stored.
When using this function, set to Burst mode as
“Wired HART Enabled”.
