Remote Configuration via Fieldbus Payload for Distributed Control Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In industrial automation networks, configuring and updating I/O modules in remote, isolated locations is challenging due to the difficulty in accessing these modules for physical configuration or file updates.
Innovation Solution
A method for automatically distributing configuration files via a fieldbus protocol, such as CANopen, from a master device to slave devices, allowing for remote configuration and updates by comparing file parameters and sending new configurations as needed, ensuring that I/O modules are correctly configured and updated.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If physical access is required to configure remote I/O modules, then configuration accuracy can be ensured, but access difficulty increases and maintenance time increases
Solution Approach 1:
The patent replaces the mechanical/physical configuration method with an electronic/digital method. Configuration files are transmitted electronically through the fieldbus network to remote I/O modules, eliminating the need for physical access to each module while maintaining configuration accuracy through standardized file formats and automated validation processes.
Solution Approach 2:
The patent introduces a configuration file as an intermediary carrier that contains all necessary configuration data. This file is transmitted through the fieldbus network to remote modules, serving as a mediator that transfers configuration information without requiring direct physical interaction with the target modules.
2Reliability
If physical access is required to update configuration files, then configuration integrity can be maintained, but maintenance time increases
Solution Approach 1:
The patent enables continuous configuration updates through the fieldbus network without interrupting system operation. Configuration files can be updated remotely and continuously transmitted to multiple modules, maintaining configuration integrity through validation while eliminating the need for system shutdowns or physical access during maintenance.
Solution Approach 2:
The patent implements self-service capabilities where the master controller automatically manages configuration file distribution to remote modules. The system autonomously handles file transmission, validation, and application without requiring manual intervention or physical access to each module, thereby maintaining integrity while reducing maintenance time.
3Ease of operation
If remote configuration is implemented via fieldbus protocol, then access ease improves and maintenance time reduces, but protocol complexity increases
Solution Approach 1:
The patent leverages the fieldbus protocol's multi-functionality to handle both control commands and configuration file transmission through the same communication infrastructure. This universal approach simplifies access by using existing network connections while managing protocol complexity through standardized configuration file formats and structured transmission procedures.
