Configuration via Web Interface
2. Before you create the
MODBUS Mapping
, you must select whether you want to create the
mapping manually, semi-automatically, or automatically:
• If you select
automatic addressing
, the mapping is created automatically for all
devices of the
Operating Modes
list. If new WirelessHART devices appear in the
WirelessHART network, they are automatically added to the
Operating Modes
list,
and the mapping will also be added automatically.
• If you select
manual addressing
, you can set up the MODBUS mapping manually
or semi-automatically for all devices of the
Instrument List
. Note that if a new
WirelessHART device joins the WirelessHART network, it is added to the
Operating
Modes
list only. Because you selected manual addressing, the automatic
addressing for the devices in the
Operating Modes
list is disabled and the device
does not automatically appear in the
MODBUS Mapping
of the WirelessHART
gateway. To set up the mapping for the new device, you must import the new device
into the
Instrument List
first. After the mapping is complete, you can write the
MODBUS Mapping
from the DTM or web interface to the WirelessHART gateway.
3. In the DTM or web interface you can upload a background image and arrange the positions
for all devices of the
Instrument List
. After you set up the topology view, you can write the
information back to the WirelessHART gateway.
If a new WirelessHART device joins the WirelessHART network, it is inserted at a default
position by the WirelessHART gateway. To rearrange new devices in the DTM or web in-
terface, you can import the new device into the
Instrument List
or import the device list
from the WirelessHART gateway.
5.5.1
Instrument List
The instrument list is a copy of the
Operating Modes
list, which is currently active in the
WirelessHART gateway and represents the virtual I/O system of the WirelessHART gateway.
See chapter 2.1.3
Thus, unless the
Instrument List
is reloaded from the WirelessHART gateway, it may not
necessarily be identical to the
Operating Modes
list that is currently active in the
WirelessHART gateway.
By creating an instrument list before the devices actually join the network, you can make sure
that a device is associated with a predefined I/O card number when the network is reformed or
the WirelessHART gateway is reset. Note that the instrument list is used for editing the devices
and that the cached values of the devices are located under
Measurement
. See chapter 5.7
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.
Note!
This list is stored in a non-volatile memory of the WirelessHART gateway. The card and
channel number assignment will remain the same after a restart of the WirelessHART gateway
or software.
