Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In process industrial applications, there is no effective method to detect whether a sensor is configured correctly for a measuring point when connected to a transmitter, leading to potential errors due to missing or faulty configurations, and existing solutions are error-prone and inefficient.
Innovation Solution
A method where sensors and transmitters exchange information about their connections, with stored identification and port numbers, allowing for comparison to determine if a configuration exists, and if not, alerting the user to necessary adaptations, ensuring increased operating safety by automating the detection of missing or faulty configurations.

Engineering Contradiction Analysis
1Reliability
If the system informs the user every time that a sensor is connected that a configuration might be necessary, then the user is notified about configuration needs, but the approach is error-prone and means additional effort for customers
Solution Approach 1:
The sensor performs self-detection by comparing its stored configuration data with the actual transmitter connection status. The sensor autonomously determines whether configuration is needed without requiring manual user checks or repeated system notifications, thereby improving reliability while reducing user effort.
Solution Approach 2:
The system implements a feedback mechanism where the sensor continuously monitors its connection status and configuration state, comparing current conditions against stored reference data. This automated feedback loop ensures accurate detection of configuration needs without requiring additional user intervention or manual verification.
2Reliability
If no configuration detection method is implemented, then the system operates without additional complexity, but configurations can be forgotten leading to serious errors in process conduct
Solution Approach 1:
The sensor stores configuration reference data (transmitter ID and sensor port number) in its memory before disconnection. This preliminary action ensures that when the sensor reconnects, it can immediately compare its stored data with the current connection status to detect missing configurations, thereby ensuring process safety without adding complex real-time monitoring systems.
3Reliability
If manual configuration checking is required, then the system remains simple, but necessary configurations can be forgotten leading to errors
Solution Approach 1:
The sensor autonomously performs configuration verification by comparing its stored transmitter identification data with the actual connected transmitter. This self-service approach ensures configuration accuracy without requiring manual user intervention, maintaining operational simplicity while preventing configuration errors.

AI summary
A method in a transmitter-sensor system for detection of a missing or faulty sensor configuration when connecting a sensor to a transmitter, comprises: retrieving first information concerning the transmitter by the sensor from the transmitter; checking by an electronics of the sensor, whether second information concerning the transmitter is stored in a memory unit of the sensor; when the second information concerning the transmitter is stored in the memory unit of the sensor: retrieving the second information concerning the transmitter by the electronics of the sensor, and comparing the first information concerning the transmitter with the second information concerning the transmitter; and informing a user when the first information differs from the second information or when no second information is stored in the memory unit of the sensor. Disclosed also is a sensor and a transmitter.
