Solution Overview

Problem

The complexity and tediousness of setting identification information for multiple safety devices connected to the same network in factory automation systems, particularly when using advanced communication technologies like CIP, make the process cumbersome and error-prone.

Innovation Solution

A support device and program that automatically acquires and sets connection setting information for safety devices, using commands to compare and match identification and attribute information, reducing the need for manual input and minimizing errors.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual setting of identification information is performed for each safety device, then setting accuracy can be ensured, but the setting process becomes complicated and time-consuming

Engineering Contradiction:
Improvesetting process simplicityVSAvoidsetting time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

The system enables automatic acquisition and setting of identification information through the support device executing commands to read settings from safety devices and automatically input them to the control device, eliminating the need for manual recording and input by operators

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The support device acts as an intermediary between safety devices and the control device, automatically managing the transfer and setting of identification information, thereby simplifying the overall setting process while maintaining accuracy

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If automatic acquisition and setting of identification information is implemented, then setting time is reduced, but the risk of erroneous setting may increase

Engineering Contradiction:
Improvesetting timeVSAvoidsetting accuracy
Core Design Contradiction:
Loss of timeVSReliability

Solution Approach 1:

The system incorporates verification mechanisms where the support device reads setting identification information from safety devices, compares it with connection setting information in the control device, and ensures consistency before finalizing the setting, providing feedback to prevent erroneous settings

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The support device performs preliminary verification by reading and comparing identification information before completing the setting process, ensuring that the information to be set is correct and consistent with existing connections

Inventive Principle:
Principle #10Preliminary action

3Adaptability or versatility

If multiple safety devices are connected to the same network, then system functionality is enhanced, but the complexity of setting each device increases

Engineering Contradiction:
Improvesystem functionalityVSAvoidsetting complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The support device provides a universal solution that can automatically manage identification information for multiple different safety devices connected to the same network, handling various device types through a single automated interface rather than requiring device-specific manual procedures

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

In the present invention a control device and a safety device establish a connection in accordance with a result of a comparison of connection setting information stored in the control device and setting identification information stored in the safety device. A support device is provided with a processor for executing a support program for assisting in setting the control device. A support program includes a first command for acquiring the setting identification information from the safety device and a second command for setting, in the connection setting information corresponding to the safety device, the setting identification information acquired in response to execution of the first command. Thus, the required identification information can easily be set even when a plurality of safety devices are connected to the same network.
