Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modular control systems, such as skid-mounted systems, face challenges in integration with distributed process control systems due to proprietary protocols, configuration, and security issues, leading to manual and error-prone processes, especially when merging configurations and updating parameter mappings.
Innovation Solution
A modular controller that operates independently within a distributed process control system, allowing native integration and communication using proprietary or standard protocols, with a merge assistant to facilitate configuration data merging, identify conflicts, and automate updates, ensuring seamless operation as one or multiple nodes within the DCS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If modular control systems use proprietary protocols for independent operation, then system independence and functionality are maintained, but integration complexity and manual configuration effort increase when merging into distributed control systems
Solution Approach 1:
The patent introduces a merge assistant software application as an intermediary tool that facilitates the integration process between modular control systems with proprietary protocols and distributed control systems. This merge assistant automatically retrieves configuration data, identifies conflicts, and performs parameter mapping, thereby reducing manual configuration effort while maintaining system independence through standardized integration interfaces.
Solution Approach 2:
The patent employs automatic parameter mapping and transformation mechanisms that convert proprietary protocol parameters into standardized DCS parameters. The merge assistant automatically adjusts communication protocols, data formats, and configuration parameters during the integration process, enabling seamless merging without manual reconfiguration of each parameter.
2Manufacturing precision
If manual configuration merging is performed to integrate modular control systems, then configuration accuracy can be verified, but time consumption and human error increase
Solution Approach 1:
The merge assistant software performs self-service functions by automatically retrieving configuration data from the modular control system, identifying conflicts with existing DCS configuration, and performing parameter mapping without requiring manual intervention for each configuration item. The system verifies configuration accuracy through automated conflict detection while significantly reducing integration time.
Solution Approach 2:
The patent implements automated feedback mechanisms where the merge assistant continuously monitors the integration process, identifies configuration conflicts, and provides real-time status updates. The system automatically adjusts parameter mappings based on detected conflicts and verifies integration success through automated testing, reducing both time and human error.
3Reliability
If modular control systems are integrated as standalone units, then system reliability is maintained, but system scalability and centralized control capability are reduced
Solution Approach 1:
The patent enables modular control systems to perform multiple functions by supporting both standalone operation with proprietary protocols and integrated operation within distributed control systems. The merge assistant facilitates this multi-functionality by providing automated integration capabilities while preserving the original system architecture, allowing the same modular unit to operate reliably independently or be scaled into larger centralized systems as needed.
Data Source
AI summary
A modular control system includes a modular controller that implements control logic of the modular control system, where the controller is built natively on a platform of a distributed control system, equipment configured to perform a physical function in a process plant according to the control logic, and a configuration database storing configuration parameters of the modular control system. In a first mode of operation, the modular control system operates as a standalone module, and in a second mode of operation, the modular control system operates natively as one or several nodes of a distributed control system.
