Industrial Machine Components With Configuration History Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial machines face challenges in accurately reproducing system configurations after abnormalities occur, as existing monitoring control systems do not record past registration information, making it difficult to investigate and solve issues when system configurations change post-shipment or during maintenance.
Innovation Solution
Components and controllers with unique identification information memory and configuration history storage allow for the recording and retrieval of configuration histories, enabling the detection of changes and storing new histories, thus facilitating the reproduction of abnormality conditions for investigation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a monitoring control unit shares registration information with an external unit, then the unique registration information is shared, but past registration information is not shared, making it impossible to reproduce the configuration at the time an abnormality occurred
Solution Approach 1:
The patent applies preliminary action by having the monitoring control unit proactively store configuration history information in advance of any abnormality occurrence. The unit continuously records registration information, connection information, and configuration data in a history storage area, ensuring that past configuration states are preserved and available for later reproduction and analysis when needed for troubleshooting.
2Reliability
If configuration history is stored in the monitoring control unit, then past registration information becomes available, but the device complexity increases
Solution Approach 1:
The patent applies copying by creating simplified replicas of the system configuration state. The monitoring control unit stores configuration history information that copies essential data including registration information, connection information, and configuration data. This copied information is sufficient for reproducing abnormality conditions without requiring the entire original system state, thereby maintaining reliability while controlling complexity.
3Measurement precision
If detailed configuration information is recorded, then the ability to reproduce abnormality conditions improves, but the amount of data to be managed increases
Solution Approach 1:
The patent applies taking out by extracting only the essential configuration information needed for abnormality reproduction. The monitoring control unit selectively stores registration information, connection information, and configuration data - removing unnecessary details while preserving the critical data elements required to reproduce and analyze abnormality conditions, thus achieving measurement precision without excessive data volume.

AI summary
Components are assembled in an industrial machine together with a controller. The components each include a unique identification information memory portion and a component-side configuration history memory portion. The unique identification information memory portion stores, as unique identification information, identification information of the component itself, which is providable to the controller. The component-side configuration history memory portion stores configuration histories that each summarize, in terms of an acquisition timing from the controller, the unique identification information of the component itself, controller identification information of the controller that was used to configure the industrial machine together with the component itself, and unique identification information of other ones, than the controller, of the components, which were also used to configure the industrial machine together with the component itself.
