A diagnostic system diagnoses an abnormality of a diagnostic object by using a plurality of diagnostic logics. The diagnostic system includes an acquisition unit, a determination unit, a generation unit, and an output unit. The acquisition unit acquires diagnostic object information relating to the diagnostic object. The determination unit determines whether each of the diagnostic logics is executable or not based on the diagnostic object information. The generation unit generates a diagnostic result including information relating to whether the diagnostic logics determined by the determination unit are executable or not. The output unit outputs the diagnostic result.

An apparatus is provided comprising a first acquisition unit for acquiring a data set including a plurality of types of measurement data indicating a state of an object, a supplying unit for supplying, in response to the data set being input, the data set acquired by the first acquisition unit to a model that outputs a state indication value indicating classification of a state of the object, a first identification unit for identifying, when one of the state indication value is output from the model in response to one of the data set being supplied, at least one type of measurement data, among the plurality of types of measurement data, having a larger influence on the one state indication value than a reference, based on the one data set, and a display control unit for displaying the one state indication value and the at least one type of measurement data.

The present disclosure comprises a method, a communication module, and a system for transmitting diagnosis data of a field device that is connected to a superordinate unit via a communication loop.

A two-wire process variable transmitter for use in an industrial process includes a process variable sensor configured to sense a process variable of a process fluid of the industrial process. Output circuitry provides an output on a two-wire process control loop which is related to the sensed process variable.
