Burst Lists
Normally, a HART slave device only responds when being polled by the host. Burst mode is a
special communication mode in which a HART slave device sends data to a particular HART
command without being polled by the host. When burst mode is used, a HART slave device
can publish data (for example process values) autonomously to another device in regular
intervals. Alternatively, data can be published if the value has changed by a significant amount,
has reached a certain threshold level, or has not been updated within a default reporting time.
The WirelessHART gateway maintains a burst message list, which lists the specific commands
that are being published by each device in the WirelessHART network. Note that the burst list is
reset after power-up or network restart.
Status
The following communication statuses exist:
communication not possible
communication possible, device not identified
(flashing) communication possible, identification ongoing
device connected and identified
Dev. Status
Note that the device status displayed in the list may differ from the actual
device status because the HART status bits may be interpreted differently.
The following device statuses exist:
maintenance required
out of specification
check function
failure
Parameter
Description
Number of
Joins
Number of times the device has joined the network.
Join Time
Date and time of the most recent join.
Reliability
Percentage of the data packets generated by the wireless devices that were
correctly received by the WirelessHART gateway.
Latency
Average time taken for data packets generated by the wireless devices to
reach the WirelessHART gateway.
+
To show/hide the list of neighboring devices, click the + sign in the
+
column.
Neighbors
Lists the neighboring WirelessHART devices in reach of the selected device.
RSSI
The RSSI (Received Signal Strength Indicator) indicates the power of the
received signal for each neighboring device. Note that you must expand the
list of neighboring devices in order to see the RSSI value for each device.
Stability
Ratio of successful data packet transfers to the total number of data packet
transfers on all wireless paths in the network.
