1. A method of generating a HART alert message within a process control system, comprising the steps of:

  • uniquely associating a plurality of device conditions for a HART device with a plurality of device status conditions, each of which is indicative of a different level of severity;

    detecting a condition associated with the HART device;

    mapping the condition associated with the HART device to one of the plurality of device status conditions; and

    generating the HART alert message to include information associated with the condition associated with the HART device and the one of the plurality of device status conditions;

    wherein the step of uniquely associating the plurality of device conditions for the HART device with the plurality of device status conditions includes the step of uniquely associating the plurality of device conditions for the HART device with one of a status condition associated with a failure of the HART device, a status condition associated with maintenance of the HART device and a status condition associated with an advisable action in connection with the HART device.
