Solution Overview

Problem

The management of OT systems in industrial environments is complex due to the heterogeneity of devices and software from different manufacturers, leading to manual dependency management and challenges in distributing artifacts across different environments.

Innovation Solution

A computer-implemented procedure using an artifact management service server to manage assets in a heterogeneous environment, employing a centralized artifact register with manufacturer-independent manifest descriptions to describe artifact content and dependencies, and a field management gateway for communication between field devices and the management server.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual dependency management is used for artifacts in heterogeneous OT environments, then flexibility in handling different manufacturer tools is maintained, but management complexity and time consumption increase significantly

Engineering Contradiction:

Improveartifact managementVSAvoidtime for finding and comparing artifacts

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent introduces an artifact registry as an intermediary component that centralizes artifact storage and provides standardized access interfaces. This registry acts as a mediator between diverse OT devices and management tools, enabling automated artifact resolution without manual intervention while maintaining compatibility with heterogeneous manufacturer-specific tools through standardized query and distribution protocols.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent transforms artifact management from a manual process to an automated one by changing the operational parameters through machine-readable dependency information. This includes encoding artifact metadata, version information, and dependency relationships in standardized formats that enable automated comparison, selection, and distribution processes, thereby reducing time loss while maintaining operational flexibility.

Inventive Principle:

Principle #35Parameter changes

2Adaptability or versatility

If vendor-specific artifact distribution channels are used, then compatibility with individual manufacturer tools is ensured, but cross-manufacturer management capability is lost

Engineering Contradiction:

Improvecross-manufacturer managementVSAvoidmanagement system architecture

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The artifact registry is designed with universal functionality to serve multiple manufacturer-specific tools and diverse OT devices through a single standardized interface. It implements vendor-independent manifest descriptions that can represent artifacts from any manufacturer, enabling cross-manufacturer artifact management while maintaining compatibility with individual tool requirements through standardized protocols.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent segments the management system into distinct functional components: the artifact registry for centralized storage and management, field management gateways for device-specific interactions, and standardized interfaces for communication. This segmentation allows each component to handle manufacturer-specific complexities independently while contributing to unified cross-manufacturer management capability.

Inventive Principle:

Principle #1Segmentation

3Extent of automation

If no standardized artifact format is used, then manufacturer-specific requirements are met, but automated dependency management becomes impossible

Engineering Contradiction:

Improvedependency managementVSAvoidartifact format standardization

Core Design Contradiction:

Extent of automationVSDevice complexity

Solution Approach 1:

The patent introduces standardized artifact formats with machine-readable metadata that encode dependency information, versioning, and compatibility requirements. This parameter standardization enables automated dependency resolution by providing structured data that management tools can process automatically, while the flexible schema accommodates manufacturer-specific requirements through extensible metadata fields.

Inventive Principle:

Principle #35Parameter changes

AI summary

Managing an OT fleet confronts the operator and the respective service technicians with the high complexity of the heterogeneous environment. Based on the systems and devices used, they must deal with a multitude of tools for processing and manipulating information. The invention therefore relates to a method for managing assets in a heterogeneous environment within a plant. This management is carried out by an artifact management service server, wherein information about the assets is stored as an artifact in at least one register. The information includes: - the software artifact with the packaged binary content, - an artifact manifest component (11) for describing the content and dependencies of the artifact, i.e., the package including formatting in which the metadata is contained, and - a metadata component (12) with normalized descriptive information about the artifact.
