1. Download SST-TS-CFG software from www.sstautomation.com/Download1/ and install it.
2. Download the GSDML file for GT200-PN-3RS from www.sstautomation.com/Download1/.
3. Build your configuration using SST-TS-CFG and download it to the gateway. When the download is completed, the software will prompt to "whether to restart the gateway", click "Yes".
4. Install the appropriate device description file in your PLC's PROFINET configuration tool.
5. Configure the PROFINET network as required. Make sure that the configuration matches the configuration present in the GT200-PN-3RS. When GT200-PN-3RS establishes a connection with the PROFINET master, the gateway will display:
MS: Solid Green, NS: Solid Green.
For more information, please refer to the GT200-PN-3RS manual.

1. Connect your serial devices to the gateway’s serial interface. Depending on the product variant, the gateway features either three RS485 interfaces (GT200-PN-3RS485) or three RS232 interfaces (GT200-PN-3RS232).
Please refer to the gateway manual for more details about specific connection methods.
2. Observe the indicator lights to check the communication status.
