Abstract
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.
Claims7
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.
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.
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.
