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).

The invention claimed is: 1. A field device comprising a processor configured to diagnose an operating state of the field device by hierarchically implementing a plurality of diagnostic processes, wherein the processor holds a parameter that indicates whether to enable or disable a diagnostic result of diagnostic process in a non-volatile memory, selects whether to enable or disable a diagnostic result of at least one diagnostic process of the diagnostic processes in a diagnostic process after the at least one diagnostic process on the basis of the parameter held in the non-volatile memory, wherein disabling the diagnostic result of the one diagnostic process, causes the processor to designate the diagnostic result of the one diagnostic process as normal; and the processor performs the diagnostic process after the one diagnostic process based on the diagnostic result of one or a plurality of diagnostic processes including the designated result of the one diagnostic process. 2. A diagnostic method of a field device, comprising: a holding step of holding a parameter that indicates whether to enable or disable a diagnostic result of diagnostic process in a non-volatile memory, and 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, selecting whether to enable or disable a diagnostic result of one diagnostic process of the diagnostic processes in a diagnostic process after the at least one diagnostic process on the basis of the parameters held in the non-volatile memory, wherein disabling the diagnostic result of the one diagnostic process designates the diagnostic result of the one diagnostic process as normal, and performing a diagnostic process after the one diagnostic process based on the diagnostic result of one or a plurality of diagnostic processes including the designated result of the one diagnostic process. 3. A diagnostic apparatus configured to diagnose an operating state of a field device, comprising: a communication interface 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 processor 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 processor holds a parameter that indicates whether to enable or disable a diagnostic result of diagnostic process in a non-volatile memory, selects 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 at least one diagnostic process on the basis of the parameter held in the non-volatile memory, wherein disabling the diagnostic result of the one diagnostic process, causes the processor designates the diagnostic result of the one diagnostic process as normal, and the processor performs a diagnostic process after the one diagnostic process based on the diagnostic result of one or a plurality of diagnostic processes including the designated result of the one diagnostic process.
