Controller Module Initialization via Sequential Identity Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical systems with multiple controller modules lack an efficient method for assigning unique identities to each module within a network, leading to challenges in data communication and addressing, particularly in complex systems where manual identification is time-consuming and error-prone.
Innovation Solution
A control module circuit and method that utilize a sequential data signal to permanently identify each controller module, enabling a daisy-chain communication arrangement where each module receives and transmits identifying data, allowing for automatic programming and addressing of all modules within the system.

1Measurement precision
If manual identification method is used for controller modules, then each module can be identified with a unique identity, but the process is time-consuming and error-prone
Solution Approach 1:
The controller modules automatically generate and assign unique identities to themselves through the self-identification process. Each module receives a sequential data signal and autonomously configures its identity without requiring manual intervention, thereby eliminating human error and reducing identification time
Solution Approach 2:
The system performs identification configuration in advance during the initialization phase before the controller modules enter normal operation. The sequential data signal pre-configures all module identities in a daisy-chain arrangement, ensuring ready-to-use unique identifiers are established before system activation
2Productivity
If automated sequential identification method is used, then identification time is reduced and accuracy is improved, but the system requires a specific daisy-chain communication arrangement
Solution Approach 1:
The sequential data signal mechanism serves multiple functions: it transmits identification information, establishes communication pathways, and configures module addresses simultaneously. This multi-functional approach reduces the need for separate dedicated identification hardware or complex communication protocols
Solution Approach 2:
The identification process is segmented into sequential steps corresponding to the daisy-chain physical arrangement. Each controller module processes identification data in a defined sequence, with the first module receiving the signal first and subsequent modules receiving it in order, simplifying the identification logic for each individual module

AI summary
The present disclosure relates to a control module circuit having a circuit communication input port, a circuit communication output port, a first controllable unit that has a first controller module, and a second controllable unit having a second controller module. The first controller module has a first communication input port connected with the circuit communication input port and a first communication output port. The second controller module has a second communication input port connected with the first communication output port and a second communication output port connected with the circuit communication output port. The first and second controllable units are adapted to be identified with a permanent identity by way of a transmittable data signal receivable at the communication input port and sequentially received by the first and second controllable units.
