    摘要： A wire electrical discharge machine includes: a drive controller configured to periodically apply voltage pulses between a workpiece and a wire electrode while relatively moving the wire electrode relative to the workpiece according to a machining program and a machining condition; a code analyzer configured to analyze the presence or absence of a condition change code for changing the machining condition in the machining program; and a condition changer configured to change the machining condition in accordance with a ratio indicated in the condition change code when the condition change code is present.

    摘要： To improve integrity of time synchronization, a node in the safety rated system takes steps to ensure the time to which it is synchronized has not become corrupted. The node receives a synchronize request message from an adjacent network device, which includes the master time, and the node generates an offset value corresponding to a difference between a local time and the master time. The node stores the offset time into a safety memory to ensure that the offset value has data integrity and does not become corrupted. The node performs periodic skew detection between two devices to verify that the clocks remain synchronized. In addition, the node performs a local drift detection to detect if the frequency of the local oscillator on which the local clock value is based begins to change.

    摘要： In a board production line having multiple work devices arranged to transfer a board from upstream to downstream and perform a predetermined operation on the board, the board production line comprising: a shared folder having storage areas configured to store board-related information, the storage areas being multiply divided according to the number of the work devices, and transferring the board-related information among the storage areas, in conjunction with transferring the board, with a first work device capable of accessing the storage areas among the multiple work devices, and a management proxy section configured to access the shared folder in place of a second work device which cannot access the storage areas, and configured to manage the board-related information so that the board-related information can be transferred among the storage areas.

    摘要： Provided is a method and system for detection of anomalous work pieces that includes computing at least one deviation data signal for a target data signal of a target work piece with respect to reference data signals recorded for a corresponding production process step of a set of reference work pieces, performing a stepwise anomaly detection by data processing of the at least one computed deviation data signal and a process type indicator indicating a type of the production process step using a trained anomaly detection data model to calculate for each time step or path length step of the production process step an anomaly probability that the respective time step or path length step is anomalous, and classifying the target work piece and/or the production process step as being anomalous or not anomalous on the basis of the calculated anomaly probabilities.

    摘要： An industrial installation or production facility and a method for managing and controlling production resources with one or more work cells. Certain production resources are organized into work cells, which are each formed from at least one processing machine of the plastics-processing industry and at least one peripheral device. The production resources are connected to a work cell controller, and are automatically detected by the work cell controller, whereupon the work cell controller performs the communication or data exchange with the company-internal network, e.g., an intranet and/or an internet, and with the production resources of the work cell, and establishes direct communication between the production resources. A software update can be performed in the work cell controller during the operation of the work cell. Furthermore, the work cell controller creates a list and assigns addresses for the connected production resources.

    摘要： A non-transitory computer-readable storage medium, a system and method for automatically updating a multi-hierarchal representation of the system when building and tracking an automation engineering environment, wherein navigation schemes that automatically search for and connect to engineering objects based on predefined relations in multi-dimensional hierarchies are defined within an engineering object of the automation project in order to react to changes within a multi-disciplinary automation project, where the engineering object also includes an intelligent extraction port that automatically extracts predefined property data from a source engineering object when the source engineering object is connected to the engineering object.

    摘要： An object is to provide a servo controller which constantly optimizes parameters according to the state of a machine. A servo controller for controlling an electric motor which drives the axis of an industrial machine includes: a state value derivation unit which derives, from an operation program and/or operation plan information of the industrial machine, the chronological or event-sequential data of the state value of the electric motor or a driven member that is operated with the electric motor; and a parameter change unit which changes at least one parameter of a velocity gain, a position gain, a feedforward gain, a filter frequency and an acceleration/deceleration time constant after interpolation based on the chronological or event-sequential data derived in the state value derivation unit either chronologically or event-sequentially.
