7.7.2 Burst status
The device supports up to three Burst communications. Each
burst can be individually configured and enabled (ON) or
disabled (OFF). Depending on its configuration, each Burst
communication can have different possible Status that could be
helpful for detecting and evaluating possible critical or
anomalous situations between the gateway and the wireless
devices. If read from the wireless devices, some Burst Status
could give information about the wrong configuration of the
gateway and/or the wireless device installed. Burst status is
readible via HMI (if installed) or via dedicated section of the DTM
(see Commissioning by DTM).

(see Commissioning by DTM).
Burst status have the following structure:
“Bn: X-Y” where:
— Bn is the Burst number as B1, B2 or B3
— X-Y represent two possible channels in negotiation with
the Network Manager (Gateway) for each Burst. These
letters can assume different values:
the Network Manager (Gateway) for each Burst. These
letters can assume different values:
“O” = OFF
the associated burst has not been enabled.
If the device has joined the network bursts can be
enabled wirelessly, through wired DTM or using an
handheld terminal. In case the device has not yet
joined, burst enabling can be done through the wires
of the HART protocol or exploiting the DD file
(handheld terminal)
“N” = Negotiating phase
the associated burst is in the negotiation phase with
network manager (gateway) that is reserving the
correct resources bandwidth, timings, etc.
“R” = Reject
the associated burst setting has been refused by the
network manager due to some possible conflicts i.e:
bandwidth limitation or requested burst update period
too short. In case this value appears, review the
update period.

Figure 33: Burst visualization into DTM
“S” = Shutdown
the associated burst is in the shutdown phase. The
network manager is deleting all the resources
previously reserved at this burst. Until the burst is in
this condition, it cannot be reconfigured.
“A” = Active
the associated burst is Active/running,In this condition
the associated Burst is transmitting the selected
HART command or status to the Gateway according
to the update period.
The Bursts will be OK only when X-Y are displayed with
“A” - “A” or “A” - “O”.
“A” - “A” or “A” - “O”.
When the selected “Burst Trigger” is set to “Continuous” there
is only one channel to be negotiated with the Network Manager
and in this case the second letter is not relevant (value fixed to
“O” - OFF). When the selected “Burst Trigger” is set to any
other event (Window, Rising, Falling or On-change), there are
two channels to be negotiated with the Network manager i.e.
one for the selected trigger event and the second for the
Maximum Update Period in case the trigger event never
occurs. In this case the X-Y represents the two channels. The
three bursts are displayed cyclically with an interval of 10
seconds.

7.7.3 Status byte
The Status byte is the fifth byte of any out value and represents
the Quality of the variable. Depending by which of the two
selections is active, the list of the possible Status can be the
