Publish mode
The device publishes all device variables and status in three bursts. In cases where a third
party host or other control system configures the burst configuration in a custom mode,
the DD allows the user to reset the burst configuration to the default burst mode.
However, it is strongly recommended that the device bursting not be manipulated as it
has been optimized to provide all device variables and status bytes, hence allowing any
potential data from the device to be cached in the gateway, minimizing opportunity for
errant communication from a 3rd party host or other control system to wake the device
due to burst misconfiguration.
Update rate
The default update rate is 60 minutes. This is the maximum (fastest) recommended
update rate. You can change this at commissioning or at any time through AMS Device
Manager, the Trex Communicator, or the Smart Wireless gateway web server.
The update rate can be set from 1 minute to 60 minutes (with 1 second resolution) and
from 1 hour to 24 hours (with 1 hour resolution, always rounding to the next hour).
When the update rate is greater than 1 hour, the device will publish the last measurement
every hour (meeting the HART requirement to at least publish data once / hour) and will
publish the new data set on the update rate.
Reducing the update rate minimizes power consumption and extends the life of the
battery.
