Fieldbus Interface Listening for Configuration Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Computer-aided systems in process automation often lack access to configuration information for cyclic data traffic on fieldbuses, especially when they are from a different manufacturer than the higher-level units they are connected to.
Innovation Solution
A fieldbus interface that listens to data traffic on the fieldbus and acquires configuration information related to cyclic data traffic, allowing third-party systems to obtain this information without requiring permanent configuration or complex parameterization, and can provide it to systems like asset management and condition monitoring systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If computer-aided systems are designed separately from higher-level units, then they can be used across multiple fieldbus segments, but they cannot access configuration information regarding cyclic data traffic on the fieldbus
Solution Approach 1:
A fieldbus interface is introduced as an intermediary component that sits between the fieldbus and external systems. This interface captures configuration information from the fieldbus traffic and makes it available to third-party computer-aided systems, thereby mediating the information access problem while maintaining system architectural independence
2Loss of information
If fieldbus interface captures configuration information by listening to data traffic, then third-party systems can access configuration information, but it may burden the fieldbus traffic
Solution Approach 1:
The fieldbus interface creates a copy of the configuration information by listening to and capturing telegrams transmitted on the fieldbus. Instead of interfering with the original data traffic, it generates a separate copy of the configuration data that can be provided to external systems, thus avoiding burdening the fieldbus traffic while still enabling information access
3Reliability
If permanent configuration is required for fieldbus interface, then configuration information can be provided accurately, but complex parameterization is required
Solution Approach 1:
The fieldbus interface automatically captures configuration information directly from the fieldbus traffic during runtime without requiring manual parameterization or permanent configuration. The interface serves itself by listening to and extracting configuration data from the actual fieldbus communications, thereby achieving reliable configuration information provision while eliminating complex setup procedures
