I/O Module Configuration Data Caching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack an efficient method for caching and providing configuration data between modules, particularly in scenarios where an I/O module is replaced or reset, leading to disruptions in data derivation and transmission.
Innovation Solution
An I/O module is designed with a housing for linking to other modules, an interface for data exchange, and a memory to store and provide configuration data. This module can receive, store, and transmit configuration data to other modules, ensuring seamless alignment of configurations during replacements or resets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If configuration data is not cached in the I/O module, then the system uses less memory resources, but configuration alignment becomes inefficient during module replacements or resets
Solution Approach 1:
The patent implements configuration data caching specifically in the I/O module where it is most needed for rapid configuration alignment during replacements or resets. This local caching approach provides configuration alignment efficiency at the point of use without requiring all system components to have increased memory resources, thus resolving the contradiction between reliability improvement and memory resource consumption.
2Ease of operation
If configuration data is cached in the I/O module, then configuration alignment during replacements is improved, but the device complexity increases
Solution Approach 1:
The patent caches configuration data in the I/O module in advance, before any replacement or reset operation occurs. This preliminary action ensures that when a module is replaced or reset, the configuration alignment can immediately proceed using the pre-cached data, greatly simplifying the replacement operation. The added complexity of caching is offset by the significant ease of operation during critical replacement scenarios.
3Productivity
If manual configuration is performed during module replacement, then system control is maintained, but productivity decreases due to external intervention requirements
Solution Approach 1:
The patent enables the I/O module to automatically perform configuration alignment using cached configuration data when a module is replaced or reset. This self-service capability eliminates the need for external intervention or manual configuration operations, allowing the module to autonomously restore its configuration state. The result is dramatically improved productivity during replacements while maintaining appropriate levels of automation without sacrificing system control.

AI summary
An input/output module having a housing to connect the I/O module to a first module, an interface configured to exchange data with the first module, and a memory. The I/O module is set up to receive and/or store data, from which data information can be derived with regard to a configuration of the first module and to make this information available to a second module upon request.
