Configuration via Web Interface
Create MODBUS Mapping Semi-Automatically
The
Generate
tab enables you to generate the mapping table automatically according to your
specifications. You only need to select the values you want to read from the devices. After this
selection has been completed, you can generate the mapping table for all devices
automatically.

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.
Note!
The
Instrument List
must be available before you create the mapping table, because the
values for the mapping table are retrieved from the
Instrument List
.
For a detailed overview of the relationship between the configuration options in the DTM or web
interface and the data in the WirelessHART gateway, see Figure 5.19 on page 63.
