Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If HMI interface diagrams are converted into computer-readable formats and automatically extracted for early model data generation, then the ability to consider overall plant functionality in early engineering stages is improved, but the complexity of data processing and integration increases
Solution Approach 1:
The patent creates a digital copy of the HMI interface diagram in a standardized computer-readable format (AutomationML). This copy contains all topology information and can be automatically processed without requiring complex interpretation of the original diagram formats, thus reducing processing complexity while enabling early detection of design faults
Solution Approach 2:
The patent introduces a standardized intermediate data format (AutomationML) that serves as a mediator between different engineering tools and processes. This intermediate format enables automatic extraction and integration of topology data from HMI diagrams without requiring complex direct integration between disparate systems
2Productivity
If standardized computer-readable formats are implemented for plant model data exchange, then the efficiency of engineering processes is improved, but the initial implementation cost and complexity increase
Solution Approach 1:
The patent implements a universal standardized format (AutomationML) that can be used across multiple engineering disciplines and tools for plant topology data exchange. This single format replaces multiple specialized formats, improving overall engineering efficiency while the standardization actually reduces long-term complexity by providing a common interface
Solution Approach 2:
The patent establishes the standardized format and data extraction processes during the early planning and design phases, rather than attempting to retrofit existing processes. This preliminary implementation of standardization enables seamless integration from the outset, improving productivity without creating implementation complexity later
3Measurement precision
If automatic extraction of model data from HMI diagrams is implemented, then the accuracy of topology information is improved, but the requirement for automated processing tools and expertise increases
Solution Approach 1:
The patent creates an accurate digital copy of the HMI diagram topology information in a standardized format that preserves all connection and device details. This copying process with proper validation ensures high accuracy of extracted data while using established conversion techniques rather than requiring complex new extraction algorithms
Solution Approach 2:
The patent implements validation and verification processes that provide feedback on the extracted model data quality. This feedback mechanism ensures accuracy by identifying and correcting errors in the extracted topology information, while using systematic validation rules rather than complex artificial intelligence

AI summary
A method for generating model data of a plant having at least one sub-part involves: providing at least one respective diagram of an HMI interface for a respective sub-part, which contains topology information thereof; transferring the respective diagram, if necessary, into a computer readable form; importing the respective transferred diagram into a data storage of a computer and preferably automatically extracting model data of the respective sub-part therefrom, wherein the model data describe at least in part the topology of the respective sub-part; and providing the model data to an interface of the computer, wherein extracting model data from a diagram involves: detection of plant objects; and detection of plant object connections.
