Automation Control Assembly With Visual I/O Order Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing control assemblies for automation systems face challenges in easily verifying the correct order of I/O modules, leading to potential wiring errors due to cumbersome methods for establishing a clear relationship between physical and logical orders.
Innovation Solution
A control assembly with row modules equipped with indicator elements that change state in response to test signals, allowing users to visually confirm the correct order through a running light effect, eliminating the need for additional contacts and enabling verification at any time, including before, during, or after startup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If additional contacts are provided to determine or check the order of I/O modules, then automatic assignment of physical I/O modules to planned I/O modules is enabled, but the correct order of physical I/O modules cannot be directly identified or checked by the user
Solution Approach 1:
The patent uses indicator elements (such as LEDs) that change their state (e.g., light up or change color) to visually indicate the order of I/O modules. This allows users to directly see the correct physical order matching the planned logical order, resolving the contradiction by providing both automatic assignment capability and direct visual identification without requiring additional contacts.
2Measurement precision
If manual assignment using unique features such as serial numbers or MAC addresses is used, then physical I/O modules can be assigned to planned I/O modules, but the correct order is cumbersome for the user and cannot be directly identified
Solution Approach 1:
The patent creates a visual copy or representation of the logical I/O module order through indicator elements on the physical modules. Instead of requiring users to manually match serial numbers or MAC addresses, the indicator elements provide a direct visual copy of the correct sequence, making assignment accurate and simultaneously easy to verify.
3Measurement precision
If DIP switches or rotary switches are used to set indicators manually, then physical I/O modules can be assigned to planned I/O modules, but verification of correct order is cumbersome and time-consuming
Solution Approach 1:
The system performs self-verification through the indicator elements that automatically indicate the correct order. The control unit communicates with the I/O modules and the indicator elements automatically show whether the physical order matches the planned order, eliminating the need for manual verification with DIP switches and significantly reducing verification time.
4Device complexity
If no visual indication system is provided, then the control assembly structure remains simple, but wiring errors occur due to inability to verify module order
Solution Approach 1:
The patent introduces indicator elements (such as LEDs with different colors or states) that provide visual feedback on the correct ordering of I/O modules. This adds minimal complexity to the structure while dramatically improving wiring reliability by allowing users to visually verify that physical modules are installed in the correct sequence before proceeding with wiring.

AI summary
A control assembly of an automation system, having at least two row modules which are arranged in a row one after the other and have an actual order, includes a control and/or communication module and/or an I/O module, as well as a test module. The row modules are each equipped with an indicator element which can assume two distinguishable states. Further, a test method for the control assembly.
