Burst Mode
WARNING
Mortal danger!
The update period (Update Period) and maximum update period (Maximum
Update Period) are not under Dräger's control.
Longer update periods will lead to a delay in the time the alarm is activated.
► Check parameters at the gateway and ensure that they are not changed
unintentionally.
WARNING
Mortal danger!
If the gas detector is configured without being connected to the WirelessHART
network (offline) it cannot be ensured that the required times of the update
period and the maximum update period are accepted by the gateway.
► Check burst mode configuration as well as update period and maximum
update period at the gateway.
The gas detector has the status of a client in a client-server relationship. For this
reason, the gas detector may not send any gas reading (Primary Value [PV]) (or
other information), without being asked to do so by the client. In contrast to that,
burst mode (Burst Mode) is method which can be used to send information
without being requested. The gas detector allows all configurations allowed by
FieldComm Group, Inc.. However, these configurations may not lead to the
alarm being activated quickly and a gas reading being obtained when a defined
gas concentration is exceeded.
Three different burst messages (Burst Messages) can be configured with the
gas detector.
Dräger recommends using the factory configuration or a burst mode
configuration optimized by Dräger for various scopes.
The configurations can be changed according to the requirements. If in doubt,
contact Dräger.
Various configurations of burst messages are described below. These can be
selected via PolySoft on the corresponding tab for burst mode configuration.
The pre-configured burst messages have .bmcf as a file suffix and can be
edited with a text editor and read in again by PolySoft.
Sending information affects the battery runtime. Sending burst messages
too frequently may result in shortened battery runtime.
48 Instructions for use |
Dräger Polytron
9.1

Standard configurations

Burst message (Burst Message) 1: Variables from command (Command) 9 with
gas reading (Primary Value [PV]) in variable slot (Variable Slot) 0 are sent
continuously (Continuous).
Burst message (Burst Message) 2: Information from command (Command) 48
(mainly errors and warnings) is sent if there is a change (On-Change) and
periodically at longer time intervals.
Burst message (Burst Message) 3: deactivated.
®
To use the standard configurations for burst mode, select the corresponding
configuration via PolySoft without resetting the gas detector to factory settings.
9.2 Configuration for toxic sensors
Burst mode configurations developed for toxic sensors can be selected via
PolySoft.
These configurations are optimized for fast alarm activation and maximum
battery runtime.
Using one of these configurations has the following effects:
Burst message (Burst Message) 1 sends information from command
(Command) 9, after the gas reading (Primary Value [PV]) at the variable slot
(Variable Slot) 0 immediately exceeded the trigger level (Trigger Level) with the
unit ppm. The following burst messages 1 are sent at update periods (Update
Periods). In addition, gas readings are continuously sent regardless of whether
the trigger threshold is exceeded.
Pre-configured burst messages with different trigger limits can be selected
via PolySoft.
Burst message (Burst Message) 2 sends information (mainly errors and
warnings) from command (Command) 48 if there is a change (On-Change) and
periodically at longer intervals.
Burst message (Burst Message) 3 is deactivated.
