Solution Overview

Problem

Distributed control systems from different manufacturers lack standard protocols to monitor and interact with Foundation Fieldbus devices, making it complex, costly, and time-consuming to provide alarm and alert monitoring and interaction capabilities.

Innovation Solution

The implementation of the Object Linking and Embedding for Process Control Alarm and Event (OPC AE) protocol enables Foundation Fieldbus devices to provide device information to an OPC AE server, allowing standardized visualization and management of alarms and alerts across different control systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If distributed control systems from different manufacturers are used to monitor Foundation Fieldbus devices, then device monitoring capability is provided, but system complexity and integration cost increase due to lack of standard protocols

Engineering Contradiction:
Improvedevice monitoring capabilityVSAvoidsystem integration complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces an OPC AE server as an intermediary component that sits between Foundation Fieldbus devices and distributed control systems. This server translates device information into standardized OPC AE protocol messages, enabling different control systems to communicate with Fieldbus devices uniformly without requiring manufacturer-specific integration logic.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The OPC AE server provides universal interface capabilities that work across multiple control system manufacturers and Foundation Fieldbus device types. By implementing a single standardized protocol interface, the system achieves multi-functionality in communicating with diverse devices without requiring separate integration solutions for each manufacturer.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If manufacturer-specific protocols are implemented for each control system, then precise device interaction is achieved, but implementation cost and time consumption increase

Engineering Contradiction:
Improvedevice interaction precisionVSAvoidimplementation time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent changes the communication parameter from manufacturer-specific proprietary protocols to a standardized OPC AE protocol. This parameter change maintains the precision of device interaction through standardized message formats while dramatically reducing implementation time and cost by eliminating the need to develop and maintain multiple custom protocol integrations.

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If multiple customization interfaces are developed for different control systems, then specific control system requirements are met, but development cost and complexity increase

Engineering Contradiction:
Improvecontrol system compatibilityVSAvoidinterface development cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The OPC AE server implements a universal interface that serves multiple control system manufacturers through a single standardized protocol implementation. This eliminates the need to develop separate customization interfaces for each control system, thereby reducing development cost while maintaining broad compatibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)
