PROCESS ABNORMALITY IDENTIFICATION USING MEASUREMENT VIOLATION ANALYSIS
The subject matter of this specification can be implemented in, among other things, a method, system, and/or device to receive current metrology data for an operation on a current sample in a fabrication process. The metrology data includes a current value for a parameter at each of one or more locations on the current sample. The method further includes determining a current rate of change of the parameter value for each of the one or more locations. The current rate of change is associated with the current sample. The method further includes identifying one or more violating locations each having an associated current rate of change of the parameter value that is greater than an associated reference rate of change of the parameter value, and identifying an instance of abnormality of the fabrication process based on the one or more violating locations.
Process abnormality identification using measurement violation analysis
The subject matter of this specification can be implemented in, among other things, a method, system, and/or device to receive current metrology data for an operation on a current sample in a fabrication process. The metrology data includes a current value for a parameter at each of one or more locations on the current sample. The method includes obtaining a reference rate of change of the parameter value of the parameter for each of the one or more locations. The method further includes determining a current rate of change of the parameter value for each of the one or more locations. The current rate of change is associated with the current sample. The method further includes comparing the current rate of change of the parameter value to the reference rate of change of the parameter value and identifying an instance of abnormality of the fabrication process based on the comparison.
Systems and methods for balancing loads in an industrial automation system
An industrial control system may receive processing information from at least two control systems associated with at least two components within an industrial automation system. The processing information may include a processing load value for each of the at least two control systems. The industrial control system may then distribute processing loads associated with the at least two control systems when a total processing load between the at least two control systems is unbalanced.

ENVIRONMENTAL TEMPERATURE CHANGE PREDICTION DEVICE AND PREDICTION METHOD FOR MACHINE TOOL
An environmental temperature change prediction device includes an environmental temperature acquisition unit, an outside temperature acquisition unit, a plant environment pattern setting unit, a prediction model generating unit, and an environmental temperature change prediction unit. The environmental temperature acquisition unit measures a machine body temperature. The plant environment pattern setting unit defines in advance a classification rule for classifying change trends of the environmental temperature into a plurality of patterns based on data of the environmental temperature and the plant outside temperature and environmental temperature prediction models. The prediction model generating unit selects the applicable plant environment pattern and determines a parameter of the environmental temperature prediction model corresponding to the selected plant environment pattern. The environmental temperature change prediction unit predicts a change in the environmental temperature in a future by the environmental temperature prediction model generated in the prediction model generating unit.

Method and system for monitoring machine health to improve machine cycle time impact
The present disclosure is directed toward a method for monitoring health of a machining tool operable in a machining state to form a workpiece and a non-machining state. The method includes determining whether a machine health routine is to be performed based on a machine health record stored by the control system, and retrieving a non-machining cyclic schedule, in response to the machine health routine having to be performed, where the non-machining cyclic schedule defines a timetable for performing one or more maintenance routines. The method further includes identifying a primary maintenance routine from among the one or more maintenance routines based on the non-machining cyclic schedule, and scheduling the machine health routine with the primary maintenance routine.
Systems and methods for broadcasting data and data tags associated with an industrial automation system
An industrial control system may receive data associated with at least one component within an industrial automation system. The industrial control system may then determine whether the data is associated with at least one of a plurality of data tags, such that the at least one of the plurality of data tags describes at least one characteristic of the data. The industrial control system may then broadcast the data and the at least one of the plurality of data tags in a data feed channel when the data is associated with the at least one of the plurality of data tags.
