Automated Bus Node Address Assignment via Detectable Actions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for assigning addresses to bus nodes in installations are cumbersome, requiring point-to-point connections and manual adjustments with DIP switches, which slows down the start-up process and limits flexibility.
Innovation Solution
A method where a central computer or start-up computer sends address information via the bus system, requiring a specific action from each bus node to accept and respond, allowing for automated address assignment during production or start-up, using various detectable actions such as rotation or voice recognition, and enabling addresses to be reassigned upon power cycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If DIP switches are used to assign addresses to bus nodes, then address assignment is possible, but the start-up process becomes slow and manual adjustments are required
Solution Approach 1:
The patent replaces the mechanical DIP switch system with an automated electronic address assignment system. The central computer communicates address information electronically to bus nodes through the bus system, eliminating the need for manual mechanical switch adjustments and significantly reducing start-up time.
Solution Approach 2:
The bus nodes automatically receive and store address information from the central computer without requiring manual intervention. The system performs self-configuration through automated communication protocols, where each bus node independently accepts and stores its assigned address.
2Adaptability or versatility
If point-to-point connections are made to each drive for address assignment, then addresses can be assigned, but the process becomes cumbersome and time-consuming
Solution Approach 1:
The patent merges multiple individual address assignment operations into a single automated process. Instead of requiring separate point-to-point connections to each drive, the central computer communicates with all bus nodes simultaneously through the shared bus system, consolidating the assignment process.
Solution Approach 2:
The bus system serves multiple functions: it acts as both the communication medium for address assignment and the operational data bus for controlling the drives. This universal system eliminates the need for separate assignment connections and simplifies the overall architecture.
3Extent of automation
If manual DIP switch adjustments are required for address assignment, then addresses can be set, but the process lacks automation and speed
Solution Approach 1:
The patent replaces manual mechanical DIP switch operations with automated electronic communication. The central computer automatically transmits address information to bus nodes through digital signals on the bus system, achieving both high automation and fast start-up speed simultaneously.
Solution Approach 2:
The bus nodes are pre-configured to receive and store address information automatically when powered on. The addressing process is performed as a preliminary automated step during system initialization, eliminating the need for subsequent manual adjustments and enabling rapid system deployment.

AI summary
A method for assigning addresses to nodes of a bus system, and installation, bus nodes being furnished with an identical delivery address, where (i) an assigning entity, particularly a central computer, start-up computer or bus node sends information to the delivery address via the bus system, (ii) the information includes a first address, (iii) an action is performed whose effect is detected by a first bus node, (iv) the first bus node accepts the first address, (v) the first bus node sends a response to the assigning entity, and (vi) steps (i) through (v) are repeated, each time with a further address for a further bus node.
