Note:
1. To apply the mode, restart the gateway.
2. In debug mode, if the GT200-HT-DP’s serial interface is configured to “Modbus Slave” or “Universal Mode”,
it will force the RS-485 interface to be the communication port and the RS-232 interface as debugging
interface. If the GT200-HT-DP is configured as PROFIBUS DP slave, it has no effects.
2.4 Address Setting Button
The address setting button is located on the front panel of the GT200-HT-DP. It’s used to set the PROFIBUS
DP/Modbus address (range: 0 to 99).
Note: If there is no actions taken for more than 10 seconds during the address setting process, the GT200-HT-DP
will restore the previous address.

2.5 Resistor Switch
The GT200-HT-DP has an internal series resistor (270 Ohm, 2 W) required for the HART channel, that allows up
to 13 HART instruments to be connected. When the power of the series resistor is more than 2W, you must use an
external series resistor (250 Ohm, 3 W), allowing the gateway to be connected to up to 15 HART instruments.

2.7 Topology of GT200-HT-DP and HART Instruments
Notes:
1. It is recommended to use separate power supplies for the HART instruments and the GT200-HT-EI, to ensure
stable communication.
2. To improve the communication efficiency of the field bus, it is recommended not to configure an empty node
or useless commands in the SST-HT-CFG software.
3. If there are two or more HART instruments connected in the same network, their HART LOOP wires should
be connected parallel with others.

4 Quick Start Guide
The following steps will help in quickly setting up communication between HART and PROFIBUS or Modbus.
For more details please see Chapter 5.
4.1 Connection
1. Connect the RS-232 interface of gateway and the serial port of the computer with the serial cable. For wiring
methods refer to chapter 2.6.4.
2. If you want the GT200-HT-DP to act as a PROFIBUS DP slave, connect the PROFIBUS DP PLC or control
system to the gateway. It is suggested to use the standard PROFIBUS DP connector shown in chapter 2.6.2.
If you want the GT200-HT-DP to act as a Modbus slave, connect the Modbus master to the gateway, refer to
chapter 2.6.3 or 2.6.4. The communication interface can be set in the SST-HT-CFG software.
3. Connect the HART device(s) to the HART interface, refer to the topology in chapter 2.7.
4. Connect the GT200-HT-DP with the power supply, refer to chapter 2.6.1. Power on the GT200-HT-DP.
Check the LED display and ensure that it shows “CF” indicating that the gateway is in the configuration
mode. Refer to chapter 2.4.
4.2 Configuration by SST-HT-CFG Software
1. Download, install, and run the configuration software, SST-HT-CFG, which can be found on the
GT200-HT-DP product page at sstcomm.com.
2. Turn the configuration switch to “1-OFF 2-ON”, to set the gateway to configuration mode.
3. Click the upload button on the tool bar. The Upload Configuration will pop up, in this window select the
GT200-HT-DP gateway you wish to configure and click “Upload.”
Note: This will upload the default configuration in the software, this is also how you can edit your
configuration after downloading your configuration to the gateway. If you cannot find the gateway, check
your connections and network settings.

4. Click “Field Bus” at left. Configure the parameters to meet the needs of your project. The mode will
determine the behavior of the gateway.
5. Click “HartChannel0” at left. Configure the parameters located in the Configuration Section to meet the
needs of your project.
6. Right Click “HartChannel0” and Select “Add Node”. Click the newly created node and configure the Slave
parameters.
Note: Node address is automatically set to 0 in point to point mode. In multi-drop mode, the node address
can be 1 to 15.

Note: The data can be filted to display only the main variables using the Advanced Configuration Mode.
9. Once the “Fieldbus”, “HartChannel0”, Node(s), and Command(s) are configured, click the “AutoMap” icon
on the toolbar to map the HART data to the PROFIBUS DP or Modbus network.
10. Check the mapping address in the Conflict Detection window to confirm that there is no conflict.
11. Click “Download” to download your configurations into the GT200-HT-DP.
12. Turn the configuration switch to “1-OFF 2-OFF” and restart the gateway.

4.3 Configure PROFIBUS DP Modules
After finishing configuration in SST-HT-CFG software, the GT200-HT-DP should be configured into the
PROFIBUS DP network. Take STEP7 for example.
1. Import the GSD file of GT200-HT-DP. (Download at www.sstcomm.com) Find the GT200-HT-DP device in
the catalog.
2. Add a GT200-HT-DP to the PROFIBUS DP bus. Set the same DP address that you have configured for
GT200-HT-DP.
3. Add some modules for GT200-HT-DP and set the data address. For more details of PROFIBUS DP module,
please see chapter 7.
