Universal I/O Retrofit Configuration for Legacy Module Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The replacement of dedicated input/output modules and terminal boards with universal I/O devices is complicated by variations in wiring connections, configuration settings, and the need for manual documentation, leading to potential errors and inefficiencies in the transition process.
Innovation Solution
A software tool that assists in the conversion by accessing information about pre-existing dedicated I/O modules and terminal boards, determining compatible functions with universal I/O modules, and generating reports and configuration files to facilitate the replacement process, including options for wiring harnesses and adapters to simplify the transition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual documentation and configuration transfer methods are used for replacing dedicated I/O modules with universal I/O modules, then the replacement process can be completed, but documentation errors increase and the process time increases
Solution Approach 1:
The system performs automatic configuration transfer where the universal I/O module self-configures by receiving configuration data from the dedicated I/O module through communication interfaces, eliminating manual documentation and reducing errors while saving time
Solution Approach 2:
Manual mechanical processes (physical documentation, manual configuration entry) are replaced with automated electronic data transfer and communication protocols between modules, significantly improving accuracy and reducing time
2Ease of operation
If direct swap out method is used for replacing I/O modules, then the replacement is simple, but it is not applicable when wiring connections and configuration settings differ between modules
Solution Approach 1:
The universal I/O module is designed to perform multiple functions and accommodate different wiring configurations and communication protocols, allowing it to replace various dedicated I/O module types while maintaining ease of installation through automated adaptation
Solution Approach 2:
A communication interface and configuration transfer mechanism acts as an intermediary between the dedicated I/O module and universal I/O module, automatically translating and adapting configuration data to ensure compatibility without complicating the replacement process
3Adaptability or versatility
If multiple dedicated I/O modules are replaced with universal I/O modules, then system versatility improves, but the complexity of determining compatibility and configuring increases
Solution Approach 1:
The system uses communication interfaces to exchange data between the dedicated I/O module and universal I/O module, automatically detecting configuration parameters and adapting settings through feedback loops, which simplifies the configuration process while maintaining high versatility
Solution Approach 2:
Configuration data is prepared and transferred in advance through automated processes before the replacement is finalized, reducing on-site configuration complexity while enabling versatile module replacement

AI summary
Described are systems, methods and computer-program product for replacing a prior input/output (I/O) module and terminal board with a universal I/O device by providing software based instructions and configuration settings for the installer. The method includes provisions for new wiring changes or harnesses as well as preset adapters, converting prior device configuration settings from an I/O module, pack, and/or terminal board to new configuration settings for a programmable I/O device, generating a wiring chart for any wiring changes based on the settings, and displaying the information for the installer and/or programmer's use. This allows a universal I/O device capable of each channel having different operating modes to replace one or more of a mixture of several types of dedicated I/O modules. The installation documentation and configurations are automatically generated, reducing the chance of errors due to misinterpretation of multiple product documents while allowing the automatic transfer of product settings.
