Hello everyone, I have a RUT955 which I use to acquire data via Modbus and then send it to the cloud through MQTT. Currently, it has two WAN connections: one via SIM card and another via cable. However, I would like to know how I can configure it so that when there is no internet source, the data is stored and then forwarded once the device reconnects.
Hello,
By default, whenever your device has Modbus data collection enabled (i.e., you have a Modbus TCP/RTU client configured), the Modbus server data is stored in the Modbus database (RAM) on the router. When using the Data to Server feature to send this data to a cloud server via MQTT, any data that could not be sent due to a loss of internet connection will remain in the database. Once the device reconnects, the previously saved Modbus data is synchronized and sent to your server automatically.
Additionally, the Data to Server service includes an option to retry sending data if the initial attempt fails, which can be useful in your scenario to ensure all data is eventually delivered.
You can find all necessary details and configuration guidelines for the Data to Server functionality here:
Best regards,
Martynas, thanks for your answer.
