5 DNetStart Software Instructions
5.1 Notes Before Configuration
When the DIP of GT200-MT-DN is "1ON 2OFF", the gateway is in operation mode, and the I/O parameters of the
slave devices on the DeviceNet network can be configured through DNetStart software.
DeviceNet network configuration software DNetStart is developed by SST Automation. It needs to be used with
SSTCOMM's GT200-MT-DN or other DeviceNet master modules.
5.2 Software Main Interface
For the first time to use the DNetStart software, it requires activation code.
Click “Get Activation Code” and it will jump to sstcomm.com for activation.

WWW.SSTCOMM.COM
11
You can access DNetStart software after entering correct activation code.
Configuration window: After establishing the internet connection, display the online device and modify the
address and parameters of the device online,check the input and output data.In the offline state, you can view
device properties by dragging the device icon to the window.
Tree View: Displays registered DeviceNet devices in different ways: device type, manufacture. Under different
manufacturers, different devices are displayed separately according to the device type.
Comment Interface: Dynamic display of network scanning information, registered device information, delete
device information, etc. display the results of "find devices", "find next".

5.4 DeviceNet Device Network Configuration
EDS Registration Wizard
Users can configure different DeviceNet devices by registering new EDS files. Register the new EDS file, select
"Tools" -> "EDS wizard", or click "EDS wizard" button in the toolbar. Or directly click the right button in the
Equipment management window and select "EDS wizard" which will pop up the EDS wizard interface. The three
ways are as follows:

WWW.SSTCOMM.COM
13
EDS wizard interface is shown in the following figure:
Select "Start "and pop up the following interface:
In this interface, users can choose to register an EDS file, log out of an existing device, and change the icon of a
device.
Take "Register an EDS file" as an example to introduce the following steps for registering a new EDS file:
After selecting "Register an EDS file", click "Next step" and select the storage path of EDS file you want to
register in the pop-up interface, as shown in the figure below:

WWW.SSTCOMM.COM
14
Click "Next step" to pop up the EDS file test report interface. If there is an error in the EDS file, the error message
will be displayed in the interface, and there is no "Next step" operation. If there is no error in the file, continue the
"Next step" operation, pop-up selection device icon interface as follows:

WWW.SSTCOMM.COM
15
After selecting a device icon, click "next step" to pop up the factory information of the registered device, as shown
in the figure below:
Click "Finish" and the EDS file registration step is over. At this time, you can see the newly registered device in
the equipment Management Window.
If you want to change EDS file for the same device, please first find the device in the device management library
and right click. After logging out, re-register the new EDS file, or complete the logout operation through the EDS
operation.
PC-DeviceNet Interface Setting

WWW.SSTCOMM.COM
16
DNetStart software needs to be used together with the DeviceNet master module. First, connect GT200-MT-DN to
Ethernet, and then connect GT200-MT-DN's DeviceNet port and user's DeviceNet device to the DeviceNet
network. Power Supply of GT200-MT-DN is 24VDC..
Power Up After correctly Connecting to Power Supply,the connection of DeviceNet network can be established by
"internet connection" in the menu bar or toolbar.Click "internet connection" and pop up the path selection
interface :
Then click the interface setting, the software will display the searched device in the list, select the master station
to be configured for the interface setting:

WWW.SSTCOMM.COM
17
Notes: the interface settings configuration, "IP address" is the IP of the device selected at the time of search.
"DeviceNet Node Address" is the Address of DeviceNet Master Module. Set any value between 0 and 63, which
can't conflict with other node addresses on the bus. "DeviceNet baud rate" is the baud rate of DeviceNet master
module, 125K, 250K, 500K optional. Keep Bus Baud Rate Consistent.
5.5 DeviceNet Network Scanning
After the interface is set up, the network scanning interface pops up:
