Configuration via Web Interface
Editing the Instrument List
1. To read the
Operating Modes
list from the WirelessHART gateway using the web interface,
click
Refresh
. If using the DTM to configure the WirelessHART gateway, select the Wire-
lessHART gateway in the project tree and choose
Device > Load from device
. If using the
DTM to configure the WirelessHART gateway, you can also import the devices of the project
tree by clicking
Import Project Tree
(DTM).
2. To add a device, click into the last row of the instrument list and specify the device
parameters. Press
Enter
to confirm your entries.
You can also edit existing entries by clicking into the corresponding cells of the instrument
list.
3. To remove a device from the instrument list, click the X-sign at the end of the row. The
respective I/O card becomes vacant again.
4. To write the current instrument list to the WirelessHART gateway using the web interface,
click
Apply
. If using the DTM to configure the WirelessHART gateway, select the
WirelessHART gateway in the project tree and choose
Device > Store to device
.
Note that the consistency of the instrument list is not checked before it is applied.
To export the current instrument list to a CSV file, click
Export
(web interface) resp.
Export
CSV
(DTM).
To load the instrument list from a CSV file, click
Import
(web interface) resp.
Import CSV
(DTM).
For more information on the structure of the CSV file, see chapter 12.

Downstream Communication
The WirelessHART gateway offers a setup for downstream communication for data to be
communicated downstream to field devices for control applications. The follwoing 2 modes are
available:
On-Change Update Mode
By default, all MODBUS output variables are updated with an on-change procedure. That
means, each output status change caused by the MODBUS master is identified by the gateway
and inserted in a queue to be forwarded to the discrete field device as soon as possible.
The on-change mode is useful if you require to manage many discrete output devices without
frequently changing their output statuses. The on-change mode is based on the reliable
wireless transfer mode.
Note!
When editing the instrument list, incomplete entries are highlighted in red. These errors must
be corrected before you can apply the instrument list.
Warnings are highlighted in yellow.
Tip
If a WirelessHART gateway is replaced with a new one, we recommend that you use the
export/import functionality to transfer the settings from the old WirelessHART gateway to the
new one. Otherwise, the new WirelessHART gateway rebuilds the WirelessHART network from
scratch by default, which means that the virtual HART I/O structure in the instrument list and
the MODBUS addresses of the devices will differ from the positions and addresses that have
been defined in the old WirelessHART gateway.
Furthermore, if using the DTM to configure the WirelessHART gateway, you can prepare the
instrument list and the MODBUS mapping tables offline and export the configuration into a
CSV file. Once the WirelessHART gateway is available on site, you can import the prepared
configuration via the CSV file.
