Solution Overview
Problem
Industrial control systems face challenges in ensuring operational safety and error-free operation when integrating diverse, technologically mixed mobile manual operator-control instruments, particularly due to compatibility issues between hardware and software components and varying safety switching elements.
Innovation Solution
A data-technology-based identifier is used to characterize the hardware and software parameters of mobile manual operator-control instruments, enabling an automated compatibility check before interaction with the control system, ensuring safe operation by suppressing hazardous situations and adapting to different normative requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If mobile manual operator-control instruments with diverse hardware and software configurations are integrated into the control system, then the adaptability and versatility of the control system is improved, but the reliability and safety of operation deteriorates due to compatibility issues and varying safety switching elements
Solution Approach 1:
The system performs a preliminary compatibility check by reading and evaluating the identification data from the mobile operator-control instrument before establishing full operational connection. This advance verification ensures that only compatible devices with appropriate safety switching elements can interact with the control system, preventing safety issues before they occur.
Solution Approach 2:
The control system introduces an intermediary evaluation mechanism that mediates between the diverse mobile operator-control instruments and the control system. This intermediary layer reads identification data, evaluates compatibility, and determines whether safe operation is possible, acting as a buffer that ensures safety while maintaining adaptability.
2Reliability
If an automated compatibility check based on identification data is implemented, then the reliability and safety of operation is improved, but the device complexity and extent of automation increases
Solution Approach 1:
The mobile operator-control instrument automatically provides its own identification data containing hardware and software configuration information. The control system automatically reads and evaluates this data without requiring manual intervention, enabling the system to self-verify compatibility and maintain safety while minimizing operational complexity.
Solution Approach 2:
The system uses identification data that encodes multiple parameters including hardware configuration, software version, and safety switching element characteristics. By evaluating these parameters automatically, the system achieves comprehensive safety verification through data analysis rather than physical complexity.
3Loss of time
If diverse mobile manual operator-control instruments are allowed to connect to the control system, then the loss of time for amortization is reduced, but the object-affected harmful factors increase due to potential unsafe combinations
Solution Approach 1:
The system applies preliminary anti-action by evaluating identification data and preventing connection of incompatible or unsafe mobile operator-control instruments before they can cause hazardous situations. This proactive measure blocks potential harmful interactions while still allowing rapid amortization of compatible devices.

AI summary
A method operates an industrial control system, which includes at least one stationary control device and at least one control-technology-based manual operator-control instrument, which can be carried by an operator-control person. In at least one of the manual operator-control instruments, at least one data-technology-based identifier is resident, which represents at least the respective hardware version and the respective software status of the respective manual operator-control instrument. The mode of response of the respective control device or of the entire control system in relation to reliability or non-reliability of the establishment of a control-technology-based interaction, in relation to functional response during an active control-technology-based interaction and in relation to functional response in connection with a termination of a control-technology-based interaction between the respective control device and the manual operator-control instrument is determined or influenced in dependence on this data-technology-based identifier. In addition, a correspondingly constructed control system is specified.
