Network Discovery Service for Industrial Controller Configuration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Industrial controller systems are complex and time-consuming to configure and manage, especially for non-technical users, due to multiple layers of technology and the need for manual interaction with devices, which hinders real-time data analysis and updates.
Innovation Solution
The introduction of industrial controller devices with built-in wireless and wired communications, data storage, and configuration capabilities that automatically connect to a remote management server, allowing for centralized monitoring and configuration via an interactive graphical user interface, enabling rapid configuration and data offloading for real-time analytics and alerts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual interaction with individual controller devices is used for configuration and data collection, then device-level control is achieved, but time consumption and labor requirements increase significantly
Solution Approach 1:
A network discovery service acts as an intermediary between the HMI device and controller devices. This service automatically discovers controller devices on the network, retrieves their configuration data, and presents it to the user through a unified interface, eliminating the need for manual interaction with each individual controller device
Solution Approach 2:
The system implements self-service through automatic network discovery and data retrieval mechanisms. The HMI device automatically discovers controller devices, fetches configuration data, and updates the user interface without requiring manual intervention, allowing the system to configure and monitor itself
2Adaptability or versatility
If multiple layers of technology devices are implemented in industrial control systems, then system functionality and control capabilities are enhanced, but system complexity and difficulty of management increase
Solution Approach 1:
The HMI device is designed with universal functionality to communicate with and manage multiple types of controller devices through a single unified interface. The network discovery service provides a universal mechanism for discovering and interfacing with various controller devices, reducing the need for device-specific configuration tools and simplifying system management despite the diversity of underlying technologies
3Loss of information
If real-time data analysis from multiple controller devices is required, then operational visibility is improved, but data collection and processing time consumption increases
Solution Approach 1:
The system implements continuous data collection and processing through the network discovery service, which continuously monitors controller devices on the network and retrieves configuration and operational data in real-time. This continuous operation ensures that data is always current and available for analysis without requiring periodic manual updates
Solution Approach 2:
The network discovery service serves as an intermediary that automatically collects data from multiple controller devices, consolidates it, and makes it available for real-time analysis through the HMI device, eliminating the need for manual data gathering and enabling continuous operational visibility

AI summary
Controller devices may be configured to execute a network discovery service to identify other devices on a network, including other controller devices, user computing devices, and/or human machine interface devices. The controller devices may communicate with the devices on the network. An individual controller device may, upon connection to a human machine interface device, provide to the human machine interface device via a web server, a graphical user interface from which a user may configure the controller device or connect to another controller device on the network.
