Abstract

Official abstract text for this publication.

In order to improve the adaptability of diagnosis of an operating state of a field device, a field device 10 according to the present disclosure has a diagnoser 17 configured to diagnose an operating state of the field device 10 by hierarchically implementing a plurality of diagnostic processes. The diagnoser 17 can select whether to enable or disable a diagnostic result of at least one diagnostic process of a plurality of diagnostic processes in a diagnostic process after the one diagnostic process.

First claim

Opening claim text (preview).

1 . A field device comprising a diagnoser configured to diagnose an operating state of the field device by hierarchically implementing a plurality of diagnostic processes, wherein the diagnoser can select whether to enable or disable a diagnostic result of at least one diagnostic process of the diagnostic processes in a diagnostic process after the one diagnostic process. 2 . The field device according to claim 1 , wherein, when disabling the diagnostic result of the one diagnostic process, the diagnoser diagnoses, in the diagnostic process after the one diagnostic process, without using the disabled diagnostic result of the one diagnostic process. 3 . The field device according to claim 1 , wherein, when disabling the diagnostic result of the one diagnostic process, the diagnoser diagnoses, in the diagnostic process after the one diagnostic process, assuming that the diagnostic result of the one diagnostic process is normal. 4 . The field device according to claim 1 , wherein the diagnoser holds a parameter that indicates whether to enable or disable the diagnostic result of the one diagnostic process, and can select whether to enable or disable the diagnostic result of the one diagnostic process on the basis of the parameter. 5 . The field device according to claim 4 , wherein the diagnoser holds the parameter in a non-volatile manner. 6 . A diagnostic method of a field device, comprising a diagnostic step of diagnosing an operating state of the field device by hierarchically implementing a plurality of diagnostic processes, wherein, in the diagnostic step, it is possible to select whether to enable or disable a diagnostic result of one diagnostic process of the diagnostic processes in a diagnostic process after the one diagnostic process. 7 . A diagnostic apparatus configured to diagnose an operating state of a field device, comprising: an acquirer configured to acquire a diagnostic result by a plurality of first diagnostic processes performed in the field device for diagnosing the operating state of the field device; and a diagnoser configured to diagnose, by using the diagnostic result of the first diagnostic processes, the operating state of the field device by one or more second diagnostic processes, wherein the diagnoser can select whether to enable or disable a diagnostic result of at least one diagnostic process of the first diagnostic processes and the one or more second diagnostic processes in a diagnostic process after the one diagnostic process.
