Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple device descriptions are created for different fieldbus systems, then field devices can be integrated into different bus systems, but the number of device descriptions becomes very large and integration becomes complex and labor-intensive
Solution Approach 1:
The patent implements a universal device description format that can be used across multiple fieldbus systems (Profibus, Foundation Fieldbus, HART). Instead of creating separate device descriptions for each bus system, the invention uses a single standardized format that can be interpreted by different bus protocols, thereby reducing the number of device descriptions from many to one while maintaining compatibility with all systems.
Solution Approach 2:
The patent introduces an intermediary translation layer that converts between the universal device description format and the specific requirements of different fieldbus systems. This mediator component allows the system to work with a single universal description while still supporting multiple bus protocols, eliminating the need to maintain separate descriptions for each system.
2Ease of operation
If device descriptions are stored in configuration/management systems, then field devices can be integrated, but the integration process becomes time-consuming and requires manual input of information
Solution Approach 1:
The patent performs device description generation and validation in advance, before the actual integration process. The universal device description is pre-configured with all necessary information in a standardized format, and the system validates its compatibility with different bus systems beforehand. This preliminary preparation eliminates the need for time-consuming manual input during integration, as the device can be quickly imported and deployed.
Solution Approach 2:
The patent enables the device description to be automatically generated and validated by the system itself, without requiring manual intervention. The universal format includes self-describing elements that allow the configuration system to automatically interpret and integrate the device information, reducing the time and effort required for manual configuration and input.
3Productivity
If device descriptions are preinstalled in configuration systems, then integration can proceed, but outdated device descriptions lead to errors and require supplementation
Solution Approach 1:
The patent implements a dynamic device description system that can be updated and adapted. Instead of using static, preinstalled device descriptions that may become outdated, the system uses a universal format that can be continuously updated with the latest device information. The configuration system can dynamically retrieve and apply updated device descriptions, ensuring that the most current and accurate information is always used for integration.
Solution Approach 2:
The patent incorporates feedback mechanisms that allow the system to detect when a device description is outdated or incomplete. The configuration system continuously validates device descriptions against the universal format and can automatically request updates or supplements from device manufacturers. This feedback loop ensures that the device descriptions remain accurate and current, preventing errors during integration.

AI summary
A method for integrating at least one field device into a network of automation technology, wherein a plurality of field devices are arranged distributed in an automated plant, wherein accessing of the field devices occurs via a field access unit, which communicates with at least one automation/integration platform and at least one web server of a service provider, wherein the service provider provides for each field device a virtual image of the field device in a database, wherein the service provider transmits to the operator of the automated plant via cloud-computing web services, or Internet based services, automatically or on query, the virtual image of the field device with concrete field device- and application-specific properties at run time (the virtual image is preferably transmitted directly into the field device, and wherein the field device performs its function in the automated plant, as soon as it is integrated into the network.
