Field Bus Master Replacement via IO Link Parameter Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In field bus systems, replacing a master assembly that controls multiple IO link devices is cumbersome, as it requires replicating and re-entering parameters from all connected devices, which is time-consuming and costly, especially when no parameter server is available.
Innovation Solution
A data storage device acting as an IO link device with a memory to save and restore all parameters of connected IO link devices, allowing for easy mechanical replacement of the master assembly by reading and writing data sets directly from/to this device, eliminating the need for re-entering parameters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of repair
If a master assembly is replaced in a field bus system, then the system can be restored to functionality, but the process requires time-consuming replication and re-entry of parameters from all connected IO link devices
Solution Approach 1:
The data storage device stores parameter sets of all connected IO link devices in advance. When the master assembly is replaced, these pre-stored parameters are automatically read and transferred to the new master assembly, eliminating the need for manual parameter replication and re-entry.
Solution Approach 2:
The invention creates a copy of all IO link device parameters and stores them in an external data storage device. This copy can be quickly transferred to a replacement master assembly, avoiding the need to re-enter parameters manually or replicate them from each individual device.
2Reliability
If manual parameter replication is performed during master assembly replacement, then all IO link device parameters can be transferred, but the process becomes costly and time-consuming
Solution Approach 1:
The data storage device contains a complete copy of all IO link device parameters. This copy is automatically transferred to the replacement master assembly through digital communication, ensuring accurate parameter transfer while dramatically increasing replacement speed compared to manual methods.
Solution Approach 2:
The invention replaces manual parameter entry and replication processes with automated digital data transfer. The master assembly communicates with the data storage device to automatically read and import parameter sets, eliminating the need for manual intervention and significantly improving productivity.
3Device complexity
If no parameter server is available in the field bus system, then system complexity is reduced, but master assembly replacement becomes even more cumbersome requiring external parameter management
Solution Approach 1:
The data storage device acts as an intermediary between the replacement master assembly and the IO link devices. It stores and provides parameter sets to the master assembly, enabling easy replacement without requiring a parameter server or complex network infrastructure.
Solution Approach 2:
The data storage device serves multiple functions: it stores parameter sets for all IO link devices, provides these parameters to the master assembly during replacement, and can be used with any master assembly in the system. This universal solution works without requiring a parameter server.
