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.
