Solution Overview
Problem
Industrial operators face challenges in interacting with field devices due to the need for constant training and familiarity with various structured formats, leading to inefficiencies and potential mistakes, especially when dealing with devices from different manufacturers.
Innovation Solution
A gateway interface device (GID) with natural language processing (NLP) algorithms is used to convert user instructions from natural language to structured formats native to field devices, enabling interactive communication and reducing the complexity of interacting with multiple field devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If operators use structured formats to communicate with field devices, then communication precision is improved, but operator training time and operation complexity increase
Solution Approach 1:
The system introduces a natural language processing intermediary layer between the operator and the field device. The NLP module translates operator's natural language input into the required structured format, eliminating the need for operators to learn device-specific protocols while maintaining precise communication. This mediator handles the format conversion automatically, resolving the contradiction between precision and training time.
Solution Approach 2:
The patent replaces the mechanical learning process (operators memorizing structured formats) with an intelligent system (NLP algorithms). Instead of training operators to understand complex protocols, the system uses machine learning models to interpret natural language and generate appropriate structured commands, substituting human cognitive effort with automated intelligence.
2Adaptability or versatility
If operators learn multiple structured formats for different manufacturers, then device compatibility is improved, but operation complexity increases
Solution Approach 1:
The NLP system is designed with universal functionality to handle multiple field device manufacturers and protocols simultaneously. A single natural language interface can communicate with diverse devices by automatically adapting to their specific requirements, eliminating the need for separate learning curves for each manufacturer while maintaining broad compatibility.
Solution Approach 2:
The system dynamically changes communication parameters based on the target device type. The NLP module identifies the field device manufacturer and model, then automatically adjusts the structured format parameters accordingly. This parameter adaptation happens transparently, allowing one unified interface to work across multiple device types without increasing operational complexity.
3Measurement precision
If detailed menu navigation is provided in software packages, then communication precision is improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces manual menu navigation with natural language processing. Instead of requiring operators to navigate through hierarchical menus to access specific functions, the NLP system interprets natural language commands and directly translates them into the appropriate structured format, maintaining precision while dramatically improving ease of operation.

AI summary
A system and method for interactively communicating with a field device of an industrial automation system for performing a function in relation to monitoring and controlling an industrial process of a power plant includes a field device is associated with a gateway interface device (GID) including NLP algorithm, and communicatively coupled to an interactive device. The GID receives a first instruction associated with the function in relation to monitoring and controlling the industrial process, in natural language format, and converts the first instruction into a second instruction based on the NLP algorithm, where the second instruction has structured format native to the field device. The GID sends the second instruction to the field device for performing the function, receives an information associated to the function performed by the field device, and sends the information for displaying in the interactive device, the function performed by the field device.
