Im considering using RUT200 or TRB140 for a project. The goal is to connect Modbus TCP device or PLC data to the Arduino IoT Cloud (to create charts with data). So far i know they use a MQTT broker with TLS encryption:
Please choose the right category under the required field. The question is related to “Network” category, and the question is posted under “Telematics” category. The concerned Engineer from Network department will address the question.
To achieve this setup, the MODBUS TCP Client needs to be configured on the device. You can follow the detailed guide below for the configuration steps:
Once the client configuration is completed and the device is successfully collecting the required MODBUS data, the information can be forwarded to your remote server using the Data to Server feature, which can be found in Services → Data to Server. This functionality also supports TLS authentication, which may be required for integration with Arduino IoT Cloud.
You can find additional details about configuring Data to Server here:
After the data sender is properly configured and the data is received by your remote server, it should then be possible to use this data for visualization purposes, such as generating charts.
If you require any additional assistance during the configuration process, please feel free to let me know.
