Hello,

If you want to publish OPC UA data to your MQTT broker in cloud, then, assuming you can successfully get OPCUA data via test function, simply configure the Data to Server.

Firstly, make sure you are running the latest firmware v7.05.

In the Data to Server, create a collection:

Add OPCUA data:

On the next collection page, you can leave everything as default (you can change period in advanced settings).

Next, on the server configuration page, select MQTT as the type and enter your broker’s information, such as server’s address, port number, topic, etc.

Make sure that the collection is enabled:

This should be enough to send OPCUA data to your MQTT broker periodically (period is configured in the collection’s advanced settings).

Kind Regards,
