Abstract: In an anomaly detection method that determines whether each frame in observation data constituted by a collection of frames sent and received over a communication network system is anomalous, a difference between a data distribution of a feature amount extracted from the frame in the observation data and a data distribution for a collection of frames sent and received over the communication network system, obtained at a different timing from the observation data, is calculated. A frame having a feature amount for which the difference is predetermined value or higher is determined to be an anomalous frame. An anomaly contribution level of feature amounts extracted from the frame determined to be an anomalous frame is calculated, and an anomalous payload part, which is at least one part of the payload corresponding to the feature amount for which the anomaly contribution level is at least the predetermined value, is output.

Furthermore, when there is a possibility that the set straight path interferes with a workpiece, a region for which the workpiece has been already cut is determined, and a path not interfering with the workpiece is set with as short length as possible.

Abstract: A pre-read/analysis process is carried out to analyze a code in a block, and whether or not the analyzed data contains an inter-path waiting code is determined. When the block contains an inter-path waiting code, the pre-read/analysis process is suspended, and whether or not a preset specified condition is met is judged. When the specified condition is met, inter-path waiting is started. When the inter-path waiting is established, code analysis data created before creation of execution data is discarded, and a pre-read/analysis process on the next block is immediately started.
