Controller Service Function for External Bypass Invocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for controller development in rapid control prototyping cannot flexibly invoke internal controller functions during external bypassing, requiring specific adaptations of the program code and affecting runtime behavior.
Innovation Solution
A method that provides a service configuration on the controller to detect and execute service functionalities, allowing flexible invocation of internal controller functions by providing or receiving arguments and return values, using a service function that contains executable code to manage memory addresses dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If external bypassing is implemented using existing methods, then controller development flexibility is improved, but program code adaptations are required and runtime behavior is affected
Solution Approach 1:
The patent introduces a service function as an intermediary layer between external bypass requests and internal controller functions. This service function manages the interaction by providing or receiving arguments and return values, eliminating the need for direct program code adaptations while maintaining runtime behavior integrity
Solution Approach 2:
The patent segments the controller functionality into internal controller functions and service functions. The service function handles external bypass operations separately from the core internal functions, allowing flexible invocation without modifying the internal function code structure
2Ease of operation
If internal controller functions are invoked during external bypassing, then service functionality is improved, but program code must be adapted
Solution Approach 1:
The service function is designed to be self-sufficient by containing executable code that automatically manages memory addresses and argument passing. This self-service capability allows the service function to invoke internal controller functions without requiring external program code adaptations
3Adaptability or versatility
If service configuration is provided on the controller, then invocation flexibility is improved, but memory management complexity increases
Solution Approach 1:
The service function contains pre-stored executable code with memory addresses of internal controller functions. This preliminary preparation of memory address information allows flexible invocation at runtime without increasing memory management complexity during operation

AI summary
A method for operating a controller is provided. Program code having internal controller functions is stored on the controller, the program code being equipped with at least one service function. A service configuration for the at least one service function is provided on the controller. The method includes; detecting, in the controller, the service configuration; and executing a service functionality in accordance with the service configuration when the at least one service function is invoked. The service configuration denotes at least one internal controller function which is executed as a service functionality of the corresponding at least one service function. The at least one service function, via the service configuration, provides at least one value for at least one argument of the at least one internal controller function in the controller and/or receives at least one return value of the at least one internal controller function.
