Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing field bus modules, particularly safety-oriented ones, face challenges in parameterization, especially for third-party manufacturers, as they lack simple access to standard parameterization procedures and data formats, necessitating additional measures and software interventions during continuous operation.
Innovation Solution
A field bus module with a processing device that utilizes incoming safety-oriented field bus telegrams to select and execute different operating modes, eliminating the need for separate parameterization interfaces or additional measures by using user data within the telegrams for parameterization, allowing for seamless integration with existing control units and systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If standard parameterization procedures are used for safety-oriented field bus modules, then parameterization can be performed, but third-party manufacturers lack simple access to these procedures and data formats, requiring additional measures and software interventions
Solution Approach 1:
The field bus module is designed to perform multiple functions: it can process both cyclic process data and parameterization data through the same field bus interface. The operating mode memory allows the module to switch between different operating modes (normal operation vs. parameterization mode) based on incoming telegrams, enabling universal access for both original equipment manufacturers and third-party manufacturers without requiring separate parameterization interfaces or additional hardware.
2Ease of operation
If separate parameterization interfaces are implemented for safety-oriented field bus modules, then parameterization access is provided, but the device complexity and integration effort increase
Solution Approach 1:
The patent merges the parameterization function with the normal operational function by using the same field bus interface and telegram structure. Parameterization data is transmitted using the existing PROFINET safety telegram format, and the processing device distinguishes between parameterization mode and normal operation mode through the operating mode memory. This eliminates the need for separate parameterization interfaces, additional hardware connections, or specialized software tools, allowing parameterization to be performed through standard field bus communication.
3Productivity
If additional software interventions are required for parameterization during continuous operation, then parameterization is possible, but productivity and operational efficiency decrease
Solution Approach 1:
The field bus module performs parameterization autonomously during continuous operation by receiving parameterization telegrams through its standard field bus interface and automatically switching to parameterization mode via the operating mode memory. No external software interventions, additional control unit configurations, or specialized parameterization tools are required. The module self-manages the parameterization process by interpreting incoming telegrams and updating its configuration accordingly, while maintaining connection to the field bus system throughout the process.
