Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing process control systems face challenges in efficiently and automatically configuring exchange field devices, requiring manual intervention and resource-intensive management of configuration data.
Innovation Solution
A method and system that utilize a configuration provider to automatically recognize, configure, and manage exchange field devices by retrieving and provisioning configuration data, using communication systems like CAN open-based fieldbus or Industrial Ethernet, enabling automatic recognition and configuration of new devices while maintaining lists of identification and configuration data for efficient device management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual configuration of exchange field devices is performed, then configuration accuracy can be ensured, but time consumption and operational complexity increase
Solution Approach 1:
The configuration data of the original field device is stored in advance in the configuration provider before the device is exchanged. When a new field device is installed, the system automatically retrieves and applies the pre-stored configuration data, eliminating the need for manual reconfiguration and significantly reducing configuration time while maintaining accuracy
Solution Approach 2:
The invention creates a digital copy of the original field device's configuration data and transfers it to the new field device. This copying process ensures that the new device receives an exact replica of the required configuration parameters, maintaining configuration accuracy while automating the process to reduce time consumption
2Reliability
If manual configuration management is implemented, then configuration control can be maintained, but device complexity and resource requirements increase
Solution Approach 1:
The configuration provider automatically performs configuration data retrieval, storage, and distribution without requiring manual intervention. The system self-manages the configuration lifecycle by automatically detecting device exchanges, retrieving appropriate configuration data, and provisioning it to new devices, thereby maintaining control while reducing operational complexity
Solution Approach 2:
The configuration provider acts as an intermediary between field devices and the control system. It centralizes configuration data management and automatically handles configuration tasks, simplifying the overall system architecture by consolidating management functions in a single component rather than distributing complexity across multiple manual processes
3Productivity
If automatic configuration is implemented, then productivity is improved, but configuration data management complexity increases
Solution Approach 1:
The configuration provider is designed as a universal system that can handle multiple field device types and configurations through a single interface. It provides multi-functional capabilities including configuration retrieval, storage, validation, and distribution, thereby improving productivity across different device exchanges while managing data complexity through a unified approach

AI summary
A method provides for the automatic configuration of a field device in a process control system. The process control system comprises one or more field devices and a configuration provider. The field devices and the configuration provider are communicatively coupled via a communication system. The method comprises: the automatic retrieval and provision of configuration data of the field devices via the configuration provider; the automatic recognition of the field device via the configuration provider after the removal of a second field device from the process control system and the replacement with the field device; and the automatic configuration of the field device using the provisioned configuration data of the second field device via the configuration provider. The method further comprises the recurrent sending of an introducing message from the configuration provider to the field devices to introduce the configuration provider to the field devices. The method further comprises the registration of the field devices with the configuration provider.
