Industrial Controller Services for Interoperability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current industrial control systems face challenges in interoperability and complexity, leading to high integration costs and delayed system ramp-up due to limited consistency between products from different vendors, requiring specialized personnel and focusing on implementation details rather than functional requirements, and lacking efficient distribution of processing load across the system.
Innovation Solution
Industrial controller services provide an abstraction for an industrial communications infrastructure to enable easy location and connection of desired functionality across the infrastructure, allowing applications to efficiently integrate by associating higher-level behaviors with control system messages and facilitating communication between components through a message bus, which differs from web services by supporting industrial protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple products from different vendors are integrated, then system functionality is improved, but interoperability and consistency deteriorate
Solution Approach 1:
The patent introduces a service-oriented architecture with standardized service interfaces that act as intermediaries between components from different vendors. These services provide a common communication framework that mediates interactions, enabling interoperability without requiring direct integration between heterogeneous components.
Solution Approach 2:
The patent implements universal service interfaces that can handle multiple communication protocols and data formats. This multi-functionality allows the same service interface to work with different vendor products, providing consistency across diverse system components through a unified interaction model.
2Reliability
If detailed integration and glue logic are implemented, then system connectivity is improved, but development time and cost increase
Solution Approach 1:
The patent pre-defines standardized service interfaces and communication protocols before system integration begins. These preliminary configurations include predefined message formats, service contracts, and integration patterns that eliminate the need for custom glue logic during implementation, significantly reducing integration time while maintaining reliable connectivity.
3Manufacturing precision
If specialized personnel are used for system integration, then integration quality is improved, but cost increases
Solution Approach 1:
The patent implements self-service mechanisms through automated service discovery, configuration, and validation. The system automatically generates integration configurations, validates service contracts, and manages communication protocols without requiring specialized manual intervention, thereby maintaining high integration quality while reducing dependency on expensive specialized personnel.
4Device complexity
If processing load is concentrated in one location, then system simplicity is improved, but system reliability deteriorates
Solution Approach 1:
The patent segments processing load across multiple service instances distributed throughout the system. Each service can be independently deployed and scaled, allowing processing to be divided into manageable units that can fail independently without bringing down the entire system, thereby improving reliability while maintaining structural simplicity through modular design.
Data Source
AI summary
A message component for an industrial automation system is provided. This includes a service component that is employed to locate functionality of applications associated with a control system message bus. An operations component exchanges messages with the message bus, where the service component and the operations component form an external view to facilitate communications between the applications.
