Solution Overview
Problem
The configuration of modular safety switching devices is often complex, time-consuming, and prone to errors due to the need for logical AND links and manual setup of electronic modules, making it difficult to implement desired safety functions effectively.
Innovation Solution
A method that involves selecting a configuration data set from a database, processing it to generate a target configuration, displaying it for the worker, and comparing it in real-time to the actual configuration, with feedback on correct module placement and rotary switch settings, using a computer program and display device, and optionally utilizing lighting units for error indication.

Engineering Contradiction Analysis
1Ease of operation
If manual configuration of electronic modules is performed without automated guidance, then the configuration process allows flexibility in setup, but the process becomes time-consuming and error-prone
Solution Approach 1:
The system performs preliminary actions by automatically generating a target configuration from a configuration data set before the operator begins manual assembly. The target configuration includes predetermined module assignments and rotary switch settings that guide the operator through the configuration process, eliminating the need for complex manual calculations and reducing configuration time.
Solution Approach 2:
The system implements feedback by comparing the actual configuration (modules inserted and rotary switch positions) against the target configuration in real-time. The display device provides immediate visual feedback indicating whether modules are correctly placed and whether rotary switches are set to correct positions, allowing operators to quickly correct errors and reducing overall configuration time.
2Reliability
If complex logical AND operations are implemented manually in modular safety switching devices, then the desired safety functions can be realized, but the configuration becomes difficult and error-prone
Solution Approach 1:
The system introduces an intermediary computational layer that automatically generates the target configuration from a high-level configuration data set. This intermediary process handles the complex logical AND operations and module assignment calculations, translating them into specific module positions and rotary switch settings that the operator simply needs to implement physically, thereby reducing configuration complexity while maintaining safety function reliability.
Solution Approach 2:
The system creates a digital copy of the desired configuration in the form of a configuration data set that defines the target configuration. This digital model includes all the complex logical relationships and safety function requirements, which are then automatically translated into physical configuration instructions. The operator configures the physical device by following these instructions rather than designing the complex logic manually, reducing errors while maintaining functional reliability.
3Manufacturing precision
If real-time comparison and feedback mechanisms are added to the configuration process, then configuration accuracy is improved, but the system complexity increases
Solution Approach 1:
The system implements self-service by automatically comparing the actual configuration against the target configuration without requiring external verification tools or complex measurement equipment. The modular safety switching device itself, through its communication interface and processing unit, performs the comparison and generates feedback indications, thereby achieving high configuration accuracy while adding minimal system complexity.
