摘要： A sensor unit, a control method, and a recording medium are provided for reducing data amount of failure diagnosis data while detecting a failure of a device performing work while moving more reliably. The disclosure includes an output limiting part outputting the failure diagnosis data only for a period in which an absolute value of the acceleration is equal to or less than a predetermined threshold.

摘要： A method includes obtaining data identifying values of one or more process variables associated with an industrial process controller and identifying one or more constraint violations using the data. The method also includes, for each identified constraint violation, analyzing a behavior of the controller, a behavior of an industrial process being controlled, and how the controller was being used by at least one operator for a period of time. At least part of the period of time is prior to the identified constraint violation. The method further includes generating a graphical display based on the analysis, where the graphical display identifies one or more probable causes for at least one of the one or more constraint violations.

摘要： A method includes obtaining data associated with operation of an industrial process controller and identifying impacts of operational problems of the industrial process controller. The method also includes generating a graphical display for a user, where the graphical display presents one or more recommended actions to reduce or eliminate at least one of the impacts of at least one of the operational problems. The method further includes triggering at least one of the one or more recommended actions based on input from the user. The method could also include executing one or more analytic algorithms to process the obtained data and identify the operational problems of the industrial process controller. Each of the one or more analytic algorithms could be instantiated as a container, and multiple containers could be instantiated and executed as needed. Results of executing the one or more analytic algorithms could be transformed into a standard format.

摘要： A method includes receiving, by a processing device, first data indicative of a processing recipe. The method further includes receiving second data. The second data includes operational data associated with the processing recipe. The method further includes receiving third data. The third data includes historical data associated with the processing recipe. The method further includes performing analysis indicative of performance of a processing chamber based on the first, second, and third data. The method further includes causing performance of a corrective action in view of the analysis.

摘要： A method and device for monitoring production equipment and a storage medium includes: a measurement result of production equipment to be monitored is acquired; the measurement result of the production equipment to be monitored is evaluated on at least one evaluation dimension to obtain an evaluation result on each evaluation dimension; and a production state of the production equipment to be monitored is determined based on the evaluation result on the at least one evaluation dimension. The production state includes a normal state and an abnormal state. The at least one evaluation dimension includes at least one of a process level of products, a statistical significance of products or a distribution trend of products.

摘要： A method includes obtaining data associated with operation of a model-based industrial process controller. The method also includes identifying at least one estimated impact of at least one operational problem of the industrial process controller, where each estimated impact is expressed in terms of a lost opportunity associated with operation of the industrial process controller. The method further includes presenting the at least one estimated impact to a user. The at least one estimated impact could include impacts associated with noise or variance in process variables used by the industrial process controller, misconfiguration of an optimizer in the industrial process controller, one or more limits on one or more process variables, a quality of at least one model used by the industrial process controller, a quality of one or more inferred properties used by the industrial process controller, or one or more process variables being dropped from use by the industrial process controller.

摘要： A method includes obtaining data identifying values of one or more controlled variables associated with an industrial process controller. The method also includes identifying periods when at least one of the one or more controlled variables has been moved to an associated limit by the controller. The method further includes, for each identified period, (i) identifying a standard deviation of predicted values for the associated controlled variable and (ii) determining a control giveaway value for the associated controlled variable based on the standard deviation. The control giveaway value is associated with an offset between the associated controlled variable's average value and the associated limit. In addition, the method includes identifying variances in the one or more controlled variables using the control giveaway values and generating a graphical display identifying one or more impacts or causes for at least some of the variances.

摘要： A calibration method for numerical controlled machine tools (1), which uses a kinematic model to generate a compensation model for the positioning error occurring with the movement of the linear (X, Y, Z) and rotation axes (B, C, A) of a machine tool (1). The calibration method measures the positions of a calibration ball (6) with a measurement sequence which includes the combined movement of the calibration ball (6) around two rotation axes (C, B or C, A), wherein the measurements around a first rotation axis (C) include at least two rotational position movements around a second axis (B or A).
