Integrating a HART device in a HART modem network
1. Open the project in the process device network view.
2. Right-click the "Networks" object in the tree structure. In the shortcut menu that opens, select
the menu command Insert New Object > Communication network. The "Insert Object(s) -
<...>" dialog box opens.
3. Click the "Assign Device Type" button.
The "Insert Object(s) - Assign Device Type" dialog box opens. You can find additional
information in the section "Insert Object - Assign Device Type" dialog box.
4. To set the network properties, select the inserted HART modem network in the right window
and right-click. Select the Object Properties command in the displayed shortcut menu.
5. Enter the device-specific information in the "Communication" tab of the Properties dialog for
the HART modem network.

6. To check if the correct network and the correct port are assigned to the COM interface,
double-click the PC object in the right window. Select the COM interface object in HW
Config, and select the Object Properties menu command in the shortcut menu.
Note
The COM port is almost always "1" for notebooks. Since most PCs have two COM ports, you
must specify the port to which the HART modem is connected in this tab. Check whether the
settings for the FIFO buffer of the COM port are suitable, or immediately use a USB HART
modem.
7. To insert the HART device, select the HART modem Modbus network object in the right
window and right-click. In the displayed shortcut menu, select the Insert New Object →
Object command.
In the displayed dialog box, enter the name of the HART device

Modbus communication type: Serial or IrDA (infrared)
Serial The interface must be set accordingly on the PC station.
IrDA No additional setting required.
Once the device is within range, it is available for Modbus communication.
Only one infrared device can be coupled to Modbus at a given time. Several devices
can be coupled under Windows.
Response General timeout within which the device is allowed to report. If the timeout is too
time long, the communication is slowed. If it is too short, some devices may not be found.
