Coordinator Bus Arrangement Error Display via Subscriber Optical Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bus arrangements in automation technology lack an effective method for the coordinator to display information, especially in scenarios where errors occur or when participants cannot display status information themselves.
Innovation Solution
A bus arrangement where a coordinator can transmit information to participants' visual displays, allowing the coordinator to display status information even without a visual display, using light-emitting diodes to indicate errors through patterns, flashing, or running lights, enabling error detection and troubleshooting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the coordinator has no visual display, then the device complexity is reduced, but the coordinator cannot display information directly
Solution Approach 1:
The patent uses participants as intermediaries to display coordinator information. The coordinator transmits information to participants, which then display it on their optical displays. This allows the coordinator to display information indirectly without having its own visual display, resolving the contradiction between reduced complexity and information display capability.
2Ease of operation
If participants display local information only, then the optical display resources are used efficiently for local status, but the coordinator cannot display system-wide information
Solution Approach 1:
The patent makes the participants' optical displays multi-functional. They serve both to display local status information and to display system-wide information from the coordinator. This allows the same optical display resources to fulfill multiple purposes, resolving the contradiction between efficient local status monitoring and system-wide information display.
Solution Approach 2:
The patent implements dynamic switching of display content. Participants can switch between displaying their own local status information and displaying information received from the coordinator. This dynamic capability allows the system to adapt to different information display needs without adding permanent additional displays.
3Difficulty of detecting and measuring
If errors are not displayed visually, then troubleshooting is difficult, but adding visual displays to all devices increases device complexity
Solution Approach 1:
The patent uses participants as intermediaries to display error information. When the coordinator detects an error, it transmits the error information to participants, which then display it on their optical displays. This approach enables visual error indication without requiring every device to have its own display capabilities, thus reducing overall system complexity while improving error detection.

AI summary
A bus arrangement comprises a coordinator (13), a first and a second subscriber (1, 2) having a first and a second optical display (41, 42), and a bus (14). The bus (14) couples the coordinator (13) to the first and the second subscriber (1, 2). In a standard operating phase, the first subscriber (1) is designed to display first local information on the first optical display (41), and the second subscriber (2) is designed to display second local information on the second optical display (42). In a display operating phase, the coordinator (13) is designed to transmit first information to the first subscriber (1) displaying the first information on the first optical display (41).
