2 Quick Start Guide
The following is an example for using HPM-610. PROFIBUS DP master read the present value of the main
variables (PV) of the HART device which short address is 0.
2.1 Configuration of Gateway
2.1.1 Pre-configured settings
1. Turn the configuration bit of DIP switch of gateway to “ON”;
2. Connect the RS232 interface of gateway and the serial port of the computer with the serial cable in the
package box. Wiring methods refer to section 3.4.3 of this manual；
3. Install the configuration software HT-123.
4. Power it on, the digital Led displaying “CF” indicates that the gateway is in the configuring state.
Double-click the installed software icon HT-123 to start the gateway configuration.
2.1.2 Software configuration
1. Open the HT-123 software installed on your computer.
2. Click “Fieldbus” in the tree view on the left, then the configuration table in the figure appears to the right:

www.sibotech.net

In the first row of the table, Select “PROFIBUS SLAVE”.
When you completed to input the parameter, press “Enter” to confirm.
3. Click “HartChannel0” in the tree view on the left, with the configuration table in the figure appears to the
right:
Then you can completed the configuration of HART network.
Notes: HART protocol specifies that the slave device which address is 0 must work in single-point mode, this
allows digital communication and analog communication to exist at the same time. Slave address 1 to 15 of the
device work in multi-point mode, the analog output of the device is at the minimum value (e.g. 4mA), only allows

digital communication. The protocol also specifies that the factory address of HART slave device is 0.
4. Right-click HartChannel0, in the pop-up menu, select “Add Node”, as shown below:
5．Right-click “Node (0)”, in the pop-up menu, select Add command to add a command (command 1), then press
OK to return. The command ID you added will be shown in the left tree.

3.3.2 PROFIBUS-DP/ MODBUS address setting button
Under normal working condition of the HPM-610, press the button twice quickly, then the high bit of digital
LED starts to flash, click the button can set the high bit of PROFIBUS/MODBUS address. Then keep pressing the
button for about 3 seconds, the low bit of digital tube starts to flash, click the button can set the low bit of
PROFIBUS/MODBUS address. Finally, keep pressing the button for about 3 seconds, the address flashing three
times shows that the address was set successfully. After coming in the status of setting PROFIBUS/MODBUS
address, if no button action within ten seconds, HPM-610 exits the status of setting address automatically and
continues to display the original address. The settable range of PROFIBUS/ MODBUS address is 0 to 99
(decimal).
3.3.3 Internal / external sampling resistance switch
Users can choose to use the internal sampling resistor or external sampling resistor to get the HART signal.
The specification of the internal resistor is 270Ω, 2W. When the power of the sampling resistor is more than 2W,
you must choose to use external resistance.

3.5 Topology of HPM-610 and fieldbus devices
These digrams show outside sampling resister used and the the system wiring. Use internal sampling resister just
to replace the 250ohm to internal resister. You must select one from using internal sampling resistor or external
resistor otherwise the HART will not work.

www.sibotech.net
16
Note: 1. Some HART slave instrument need to perform self-test and other internal work when power is on, it may
not proceed with HART communication, so gateway cannot receive the response or data of the instrument right
now. It is recommended the HART slave instrument and gateway uses separate power supply so that the gateway
can immediately establish communication with instrument.
2. When configuring HART read/write commands with HT-123, the commands need to be configured
according to the actual situation. To increase the speed of bus communication, it is recommended not to configure
the empty node (node is not really connected) and empty/dummy/wrong commands.
