Industrial Plant Control Code for Modular and Legacy Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods struggle to efficiently orchestrate control logic for industrial plants that contain both modular and non-modular parts, particularly in partly modular plants, due to difficulties in integrating service-based and instrument-based control logic.
Innovation Solution
A method using a cause-and-effect matrix to define both instrument-based and service-based control logic, enabling a single-view tool for combining traditional process logic with service orchestration, allowing for the creation of control code that can handle both types of logic in a graphical and intuitive manner.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate tools are used for service-based and instrument-based control logic, then each tool can be optimized for its specific purpose, but the overall system complexity increases and integration becomes difficult
Solution Approach 1:
The patent merges service-based control logic and instrument-based control logic into a single unified cause-and-effect matrix. This allows both types of control logic to be defined, edited, and integrated within one graphical interface, eliminating the need for separate tools and reducing system complexity while improving integration reliability.
2Productivity
If a unified cause-and-effect matrix is used for both service-based and instrument-based logic, then integration is simplified and engineering time is reduced, but the interface complexity increases
Solution Approach 1:
The unified cause-and-effect matrix is segmented into distinct sections: service-based control logic entries and instrument-based control logic entries. Each section maintains its own characteristics and data structures, allowing the interface to present organized, manageable elements rather than a monolithic complex structure, thus improving ease of operation while maintaining productivity benefits.
3Adaptability or versatility
If traditional instrument-based control methods are used for modular plants, then existing systems can be maintained, but adaptability to service-oriented architecture is limited
Solution Approach 1:
The cause-and-effect matrix is designed with universal functionality to handle both service-based control logic (for modular PEAs with service-oriented architecture) and instrument-based control logic (for traditional equipment). This multi-functional capability allows the same interface and methodology to be applied across diverse plant configurations, enhancing adaptability to service orientation while maintaining ease of manufacture through consistent implementation procedures.
