Abstract
A field device for determining a process parameter value, comprising a measurement device for determining a process parameter value; circuitry for determining the reliability of the process parameter value; and signaling circuitry for providing the process parameter value and an indication of the reliability of the process parameter value to a host system via a current loop. The signaling circuitry is configurable between a first state in which the indication of the reliability is provided as a digital signal and the process parameter value is provided as an analog DC-value, and a second state in which the indication of the reliability is provided as a predetermined analog DC-value. Hereby, the number of unplanned process interruptions may be reduced when the host system is capable of receiving digital signals.
