Hi, sorry for the misunderstanding. The msg.topic contains "variable" values that is generated through the OPC-UA client node. And i would like it to display the data on the MySQL database only when i press the button on the dashboard.
The second image shows the code im trying to implement in the function node after the button node. This is what i meant by both the "msg.topic" and "msg.payload" are pre-occupied with values.
The third image is part of the configuration page of the ui-button node. there is only 2 term here that can be delivered upon button pressed. is there any other term that i can use other than these two?
