Abstract: A control device and a monitoring system of a manufacturing device, capable of enabling an external device to acquire data easily without grasping a configuration of the control device having a plurality of function control units. A control device of a manufacturing device includes a display function control unit and a control function control unit. The display function control unit includes a data model generation unit, and the control function control unit includes a data model generation unit. The display function control unit includes: a data model acquiring unit that acquires a data model generated by the data model generation unit of the control function control unit; and a data model integration unit that integrates a data model generated by the data model generation unit of the display function control unit with a data model of the control function control unit acquired by the data model acquiring unit.
Abstract: A compact data structure generation engine can be used to generate a compact data structure that represents performance data for high-scale networks. The compact data structure representing the performance data can be used to monitor the operation performed on or by a computer system to identify potentially anomalous conditions. In response, a corrective action can be taken to address the issue. This can be useful, for example, in improving the efficiency, effectiveness, and reliability of the computer system during operation.

Abstract: Systems and methods for alarm panel analysis include receiving a plurality of alarm events from the respective alarm panels monitoring corresponding buildings. An alarm analysis system may classify the alarm panels by identifying an alarm type for the alarm events. The alarm analysis system may determine a number of occurrences of each alarm type for the alarm panels, and generate a data point for a dataset for the alarm panels. The alarm analysis system may identify statistical dividers in the data points for the data set, which may be used for assigning a ranking for the alarm panels based on their location in relation to the statistical dividers. The alarm analysis system may construct and a monitoring dashboard which includes the rankings of the alarm panels, which may be rendered on a display to an end user.
