Solution Overview

Problem

On-site operators lack familiarity with tool applications needed to change IO-Link device settings during actual network operations, requiring system managers to perform pre-operation tests on multiple devices, complicating the process.

Innovation Solution

A PLC control data generation device and method that allows on-site operators to easily change IO-Link device settings by generating and transmitting setting data files to the PLC, which then updates the IO-Link devices through a user-friendly interface, eliminating the need for system manager intervention during actual operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If system manager performs pre-operation test on each IO-Link device using tool application, then setting accuracy is improved, but time consumption increases

Engineering Contradiction:
Improvesetting accuracyVSAvoidtime consumption
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The patent applies preliminary action by having the system manager perform pre-operation tests and generate setting data files before actual network operation begins. The setting data files are created in advance based on test operations, so that during actual operation, operators only need to execute pre-prepared PLC control data without performing time-consuming tests on each device individually.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent applies copying by creating setting data files that contain copied configuration information from successfully tested devices. These setting data files serve as templates that can be reused across multiple identical IO-Link devices, eliminating the need to perform individual tests on each device while maintaining setting accuracy.

Inventive Principle:
Principle #26Copying

2Ease of operation

If on-site operator uses tool application to change IO-Link device settings, then ease of operation is improved, but operator skill requirement increases

Engineering Contradiction:
Improveease of operationVSAvoidoperator skill requirement
Core Design Contradiction:
Ease of operationVSAdaptability or versatility

Solution Approach 1:

The patent introduces PLC control data as an intermediary between the tool application and the IO-Link device settings. Instead of requiring operators to directly use the complex tool application, the system provides pre-generated PLC control data that serves as a simplified interface, allowing operators to change settings through basic PLC commands without needing deep knowledge of the tool application.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system enables self-service by allowing on-site operators to independently change IO-Link device settings using the PLC control data without requiring system manager intervention. The operators can perform setting changes during actual operation using simple PLC commands, making the system self-sufficient for routine configuration tasks.

Inventive Principle:
Principle #25Self-service

3Manufacturing precision

If system manager intervenes during actual operation to change settings, then setting accuracy is improved, but productivity decreases

Engineering Contradiction:
Improvesetting accuracyVSAvoidproductivity
Core Design Contradiction:
Manufacturing precisionVSProductivity

Solution Approach 1:

The patent implements self-service by empowering on-site operators to independently perform setting changes during actual operation using the PLC control data. This eliminates the need for system manager intervention, allowing operators to resolve configuration issues immediately without waiting for specialized personnel, thereby maintaining both accuracy and productivity.

Inventive Principle:
Principle #25Self-service

AI summary

A Personal Computer (PC) that can simplify pre-actual-operation work in which an on-site operator easily changes setting of a control object device during actual operation. A PC (100) includes a setting data generation processor (111) that generates a setting data file referred to by a setting value writing FB of a PLC (200) and a transmission processor (112) that transmits the setting data file to the PLC (200). The setting value writing FB is a function block that changes an operation setting value of a control object device that is controlled by the PLC (200) based on the setting data file.
