Abstract: A method of performing online diagnostics for a valve includes receiving valve information while the valve is in operation. The valve information includes setpoint data and position data associated with the valve. The method further includes processing the setpoint data and the position data at a plurality of time intervals, and detecting an occurrence of a stick-slip based on the processing.

Abstract: Systems and methods for diagnosing components of a control system are disclosed herein. In some embodiments, the spectral content of various signals originating from a control valve is used to detect periodic patterns that can correspond to valve problems.

Abstract: A computer-implemented method for monitoring characteristic data includes selecting a first operable system device and receiving a first plurality of data from the first operable system device. The first plurality of data represents at least one characteristic of the first operable system device at a first plurality of points in time. The method also includes determining whether the first plurality of data is useful. If the data is useful, the method also includes receiving a second plurality of data from the first operable system device, the second plurality of data represents at least one characteristic of the first operable system device at a second plurality of points in time, wherein the second plurality of points in time is substantially larger than the first plurality of points in time. If the data is not useful, the method further includes selecting a second operable system device.

Abstract: A method for performing diagnostics for a valve assembly includes obtaining valve assembly information including a set of data points where each data point of the set of data points includes a position of an actuator stem. The method includes classifying each data point of the set of data points as at least one of a plurality of data point types where the plurality of data point types includes a first data point type and a second data point type. The method also includes determining at least one valve assembly characteristic based on the classification of each data point of the set of data points where determining the at least one valve assembly characteristic includes measuring the position of the actuator stem at a specific point in time.

Abstract: A computer-readable medium and method may include instructions for providing a graphical model in a computing environment, where the graphical model includes a plurality of graphical affordances. Generated code may be provided based on the graphical model, where the generated code includes a plurality of code segments. A traceability report may be generated based on the graphical model and the generated code, wherein the traceability report includes a mapping of the plurality of code segments to corresponding ones of the plurality of graphical affordances. The traceability report may be stored.
