Solution Overview
Problem
Current automation systems face challenges in adaptability due to limited integration options for decentralized peripherals, restricted mobility of sensors and actuators, and inflexible modularity, primarily because of signal interface variances and lack of standardized communication, which hinders universality, scalability, and compatibility.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If individual signal interfaces are used for different sensors and actuators, then device-specific control functionality is achieved, but system universality and compatibility deteriorate
Solution Approach 1:
The patent introduces a standardized interface layer (such as IO-Link or PROFIBUS PA) that acts as an intermediary between diverse sensors/actuators and the automation system. This interface abstracts device-specific signal variations, allowing different peripherals to communicate through a common protocol while maintaining their individual functionality. The standardized interface translates various device-specific signals into a unified communication framework, resolving the contradiction between device diversity and system universality.
Solution Approach 2:
The patent implements a universal interface standard that enables a single interface type to support multiple different sensor and actuator devices. By defining a common communication protocol and data structure that can accommodate various device types, the system achieves multi-functionality through a standardized interface. This allows the automation system to work with different peripherals without requiring device-specific interface implementations, thereby improving system universality.
2Adaptability or versatility
If decentralized peripherals are integrated using individual cables and remote I/O modules, then signal control precision is maintained, but system mobility deteriorates
Solution Approach 1:
The patent integrates multiple individual signal connections into a single consolidated communication bus or wireless connection. Instead of using separate cables for each signal (power, ground, data, control), the system merges these into a unified interface that carries multiple signals simultaneously. This reduction in physical connections directly improves mobility while maintaining full control functionality through the standardized protocol.
Solution Approach 2:
The patent replaces physical cable connections with wireless communication technologies for connecting decentralized peripherals. By substituting mechanical cable interfaces with wireless protocols, the system eliminates the mobility constraints imposed by physical cable infrastructure while maintaining signal integrity and control precision. This allows sensors and actuators to be moved freely without being constrained by cable routing.
3Adaptability or versatility
If signal-based abstraction is used for field devices, then integration into automation system is simplified, but functional capability utilization deteriorates
Solution Approach 1:
The patent implements a dynamic abstraction layer that can adapt its level of detail and functionality based on the specific device and application requirements. Rather than using a static, fixed abstraction model, the system dynamically adjusts the abstraction level to expose appropriate functional capabilities. This allows the automation system to access advanced device features when needed while maintaining simplicity for basic operations, thereby improving functional capability utilization without overwhelming complexity.
Solution Approach 2:
The patent segments the abstraction layer into multiple hierarchical levels, each handling different aspects of device communication. The lower levels handle basic signal transmission and device identification, while upper levels provide access to advanced functional capabilities. This segmentation allows the system to utilize sophisticated device features when required while maintaining a simple interface for basic operations, effectively resolving the contradiction between functional capability and abstraction complexity.

AI summary
In today's automation systems, there is a close coupling between the functional implementation and the connection thereof to the physical process. This coupling is above all characterised in that the integration possibilities of decentralised periphery are limited to the integration of individual hardware-specific signals. The invention relates to a component-based and function-encapsulating system architecture which overcomes present challenges by associating increasingly more intelligent devices in the field as functional components.
