Find Innovative SolutionsGenerate Solutions
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, lead to cumbersome operations.
Innovation Solution
A support device with a processor and memory storing a support program that assists in setting connection information by acquiring and comparing identification data from safety devices, reducing the need for manual recording and tool activation, and suppressing erroneous settings through specific commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple safety devices are connected to the same network using advanced communication technology, then communication capability is improved, but setting operation becomes complicated and troublesome
Solution Approach 1:
The support device automatically acquires setting identification information from each safety device and sets it in the control device without requiring manual intervention. The system performs self-service by autonomously completing the setting process that would otherwise require user activation of setting tools and manual recording of identification information.
Solution Approach 2:
A support device is introduced as an intermediary between the safety devices and the control device. This intermediary automatically manages the setting process by acquiring identification information from safety devices and configuring the control device, thereby eliminating the need for complex manual setting operations.
2Measurement precision
If manual setting of identification information is performed for each safety device, then setting accuracy can be maintained, but user effort and time consumption increase
Solution Approach 1:
The support device autonomously performs the setting process by automatically acquiring setting identification information from each safety device and configuring it in the control device. This eliminates manual setting operations while maintaining accuracy through automated data acquisition and configuration.
Solution Approach 2:
The manual mechanical process of recording identification information on memo paper and manually inputting it into setting tools is replaced by an automated electronic system. The support device electronically acquires and transmits identification information, substituting manual operations with automated digital processes.
3Ease of manufacture
If setting tools are activated and identification information is manually recorded, then setting process can be completed, but operational complexity increases
Solution Approach 1:
The support device serves as an intermediary that consolidates and automates the setting process. It acquires identification information from safety devices and automatically configures the control device, eliminating the need for users to activate multiple setting tools and perform complex manual operations.
Solution Approach 2:
The support device merges multiple separate setting operations into a single automated process. Instead of requiring users to activate setting tools for each safety device individually and manually record information, the support device performs all setting operations in one integrated automated workflow.

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.
