    摘要: A host system which executes an emulation environment for modelling a logical behavior of an industrial control device may execute a clock management module to scale execution time in the emulation environment to more accurately reflect execution time of the industrial control device. The clock management module may operate to receive repeatable ticks based on a real time clock of the host system. The repeatable ticks may be used to measure execution of a portion of an industrial control program in the emulation environment, which measure may be compared to a reference value for executing the same portion on the industrial control device. The host system may then temporarily stall execution in the emulation environment to match execution on the industrial control device.

    摘要: Disclosed is a computer-implemented method for generating a prediction model. The model can be for use in processing machine event data to predict behavior of a plurality of industrial machines under supervision. The prediction model can be configured to determine current and future states of the industrial machines. The method can include: extracting event features from event codes and structuring the event features into feature vectors; and generating the prediction model by clustering the feature vectors into a plurality of vector clusters, the vector clusters being assigned to respective machine states. The prediction model can be constructed based on event data from a first industrial machine and be applied to control an operating state of a second industrial machine.
