Solution Overview

Problem

In industrial networks, changing the configuration of slave devices to adapt to different production processes is complex and prone to errors due to the need for manual rewriting of configuration lists by administrators, which can be time-consuming and risky.

Innovation Solution

A control device that allows easy switching between different system configurations by using a master device with a communication unit, control unit, and recording unit, which includes multiple configuration lists and a list selection mechanism to manage slave device communications and detect abnormalities, thereby simplifying the setup change process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the configuration list is manually rewritten by administrators to adapt to different production processes, then the system can accommodate different production requirements, but the operation becomes complex and error-prone

Engineering Contradiction:
Improveadaptability to different production processesVSAvoidease of configuration change
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The system pre-stores multiple configuration lists corresponding to different production processes in the recording unit. When a setup change is needed, the administrator simply selects from the pre-stored configurations rather than manually creating them, which eliminates the complexity of manual configuration rewriting while maintaining adaptability to different production requirements

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system creates and stores copies of configuration lists for different production scenarios in advance. These copied configurations can be quickly switched between without manual intervention, allowing the system to adapt to different production processes while keeping operations simple and error-free

Inventive Principle:
Principle #26Copying

2Adaptability or versatility

If the configuration list is manually rewritten by administrators, then the system can adapt to different production processes, but the process becomes time-consuming

Engineering Contradiction:
Improveadaptability to different production processesVSAvoidtime for setup change
Core Design Contradiction:
Adaptability or versatilityVSLoss of time

Solution Approach 1:

Multiple configuration lists are prepared and stored in advance in the recording unit before any setup change is needed. When production process changes are required, the system immediately switches to the pre-stored corresponding configuration list, eliminating the time-consuming manual rewriting process while maintaining full adaptability to different production requirements

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system dynamically switches between different pre-stored configuration lists based on production requirements. This dynamic switching capability allows instant adaptation to different production processes without the time loss associated with manual configuration rewriting, as the appropriate configuration is already available in memory

Inventive Principle:
Principle #15Dynamics

3Adaptability or versatility

If the configuration list is manually rewritten by administrators, then the system can adapt to different production processes, but configuration mistakes may occur

Engineering Contradiction:
Improveadaptability to different production processesVSAvoidreliability of configuration
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

Configuration lists are carefully prepared and validated in advance, then stored in the recording unit. When setup changes are needed, the system switches to pre-validated configurations rather than allowing manual rewriting, which eliminates human error while maintaining adaptability to different production processes

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The control unit automatically compares the selected configuration list with the actual slave device connections and notifies the administrator of any mismatches. This feedback mechanism ensures configuration reliability by detecting and preventing errors, while the system maintains full adaptability through multiple pre-stored validated configurations

Inventive Principle:
Principle #23Feedback

AI summary

In a master device (control device) that employs a configuration list, setup change is performed easily without requiring a complicated operation with respect to a partial change in the configuration of a slave-side system on a slave side. A control unit (11) of a control device (10) is configured to perform communication for inquiring about device information to an address in an active configuration list through a communication unit (12), and determine to be abnormal when the result of the communication with respect to a common portion of a slave-side system (20) is different from the device information in the active configuration list.
