Automatic field device service adviser

A field device comprising a process variable transmitter, comprising:

• a process variable sensor configured to sense a process variable of an industrial process;
• a microprocessor;
• a memory operably coupled to the microprocessor;
• a plurality of diagnostic inputs operably coupled to the microprocessor;
• wherein the microprocessor implements field device resident algorithms based upon instructions stored in the memory including:
• a plurality of diagnostic algorithms based upon the plurality of diagnostic inputs, wherein the plurality of diagnostic algorithms provide a service information output indicative of actionable service information comprising a corrective service action which should be performed based upon the plurality of diagnostic inputs;
• a prediction engine implemented by a prediction algorithm configured to determine a service interval within which the corrective service action should be performed, the service interval based upon a health indication degradation curve used to predict when a health indication will reach a threshold level and wherein the prediction algorithm is modified based upon successful runtime of the process variable transmitter;
• a service message module configured to generate a service message based upon the service interval and the corrective service action;
• and
• I/O circuitry configured to transmit information related to the sensed process variable and further configured to transmit the service message including the corrective service action and an augmented service interval to another location.
