• Flow rate: Flow rate Update time period
• Total: Total Update time period
• Temperature: Temperature Update time period
• Density: Density Update time period
9.10.2 Burst Mode
When the Burst mode is enabled, the device
continuously sends up to three data listed in Table
9.1.
When the Burst mode is set to “Wired HART
Enabled”, the device continuously sends alarm
signal also.
Refer to Subsection 9.10.3 “Event Notifi cation” for
detail.
When changing the setting of Burst mode, set “Off”
to the Burst mode. Default setting is “Off”.
(1) Burst Message
The parameters for Burst Message are as
follows.
• Transmit data: command parameters of Burst
Command
• Device variables:
• Update period
• Transmit condition: choice in Burst Msg Trigger
Mode
Refer to Table 9.1 for the combination between
command parameter and transmit condition.

NOTE
• In case of Burst Mode setting change, confi rm
Burst Mode parameter is OFF.
• Prioritize to use the 'Burst Message 1'.
