Abstract
An industrial process diagnostic apparatus is provided which can identify a source, or “root cause”, of an aberration in an industrial process. A plurality of process configuration models are provided which each represent a physical (or actual) implementation of an industrial process. One of the plurality of models is selected and diagnostics performed on the process using the selected model and at least one process signal related to the process. Based upon the diagnostics, a root cause of the aberration is determined.
Claims31
An industrial process diagnostic apparatus for identifying a root cause of an aberration in an industrial process, comprising:
- a plurality of process models, each model related to a physical implementation of an industrial process;
- a model selection input configured to receive a selected model, the selected model uniquely identifying one of the process models;
- a process signal input configured to receive a plurality of process signals related to the process;
- and
- a root cause output indicative of a source of the aberration in the process, the root cause output a function of the selected model and the process signals.
A diagnostic method in an industrial process for identifying a root cause of an aberration in an industrial process, comprising:
- selecting a process model from a plurality of process models, each model related to a physical implementation of an industrial process, the selected model uniquely identifying one of the process model wherein each model includes a rule base;
- receiving a plurality of process signals related to the process;
- and
- identifying a root cause indicative of a source of the aberration in the process, the identifying as a function of the selected model and the process signals.
An industrial process diagnostic apparatus for identifying a root cause of an aberration in an industrial process, comprising:
- means for storing a plurality of process models, each model related to a physical implementation of an industrial process;
- means for receiving a model selection input uniquely identifying one of the process models;
- means for receiving a plurality of process signals related to the process;
- and
- means for identifying a root cause indicative of a source of the aberration in the process as a function of the selected model and the process signals.
