Thank you for contacting us.
I would like to ask, if you monitoring and transmit Modbus data?
If so, please follow these steps:
1. Connect to a TRB145, navigate to Services - Package manager and install Modbus Serial Master.
2. Configure Modbus serial master (add slave devices and request information).
3. Once, this done navigate Services - Data to server.
4. Add new data sender and as protocol MQTT, fill rest required information and save and apply configuration.
If everything is done correctly, MQTT data should be transmitting to the given server.
Please inform if that helps.
thank you very much for answering my question
I will try the steps you indicate and if it works I will let you know
