Abstract

A radar level gauge comprising a physical communication interface bi-directional communication of data structured according to either a first digital communication protocol or a second digital communication protocol, first communication circuitry for communicating measurement data from the field device, second communication circuitry for enabling configuration of the field device, protocol identification circuitry connected to the communication interface for intercepting data and configured to parse intercepted data to identify the digital communication protocol, and control circuitry for directing the intercepted data to one of the first and second communication circuitries based on the identified protocol.
