But what settings are you thinking to change? The most common one I would think of is for when you connect a new sensor…. However the integration with the sensor is mostly handled by the controller or consuming application, not the master. For example, parsing PD bytes to metrics…. All you are going to get from the sensor on the fieldbus is bytes or words that your application now needs to interpret specific to that sensor.
This is also true of the mqtt integration, just bytes from the master.
