  • In Basic settings enter the Device ID to identify the TD210 and for device management, if you have many TD210 connected to the server, please make sure all the ID are different and enter the number of SIM inserted in the device. Set the work mode as DTU and debug level 0. As you can see in the Fig.4.

5. Now in MODBUS settings configure your MODBUS and  RS485 sensor. Set MODBUS work mode as MODBUS disable and MODBUS Device address as 1. In ADC set all the parameters as default, please refer to below image. In the sensors section enter all the details related to your RS485 sensor which you will find in your sensor data sheet provided by the sensor manufacturer. For reference, I have used RS485 XY-MD02 temperature & humidity sensor.

Note: Communication baud rate of Basic setting and baud rate of MODBUS setting should be the same.

6. Final step towards completing the MQTT configuration. Enter MQTT credentials in Bivocom Mqtt setting from your Fogwing Account’s edge configuration page: Fogwing – > Edge Network -> IoThub Access -> MQTT.

Note: Fogwing accepts data only in JSON format so please select the data format as JSON and currently Bivocom device does not support secure connection, so use 1883 unsecure port.

Step 4: Data received over Fogwing.

Once after completion of the above steps provided everything goes in line with the above mentioned instructions, you will be able to see the data sending over to Fogwing platform.

Now you are ready to analyze your RS485 sensor data at Fogwing IIoT Platform portal, you can check all the data within the data storage in the portal.
