OPC UA is a communication protocol for the Industrial Internet of Things (IIoT). It provides a standard for the secure and reliable exchange of industrial automation data between devices and systems from different vendors and platforms.

In order to handle and manage the OPC UA address space in a scalable and efficient manner, Node4i utilizes the OPC UA MILO SDK and implements modifications on the Address Space Management. The goal is to optimize and monitor the address space in real-time with advanced features such as Redis-Search and a Lua Script Engine.

Redis-Search

Redis-Search is an efficient search engine that utilizes an in-memory data store to provide fast search results. By integrating Redis-Search into the Node4i platform, the OPC UA address space can be searched in real-time, providing quick access to the required data and reducing the latency associated with traditional database searches.

Lua Script Engine

The Lua Script Engine is a powerful scripting language that provides the ability to extend and customize the functionality of the Node4i platform. By integrating the Lua Script Engine, Node4i can execute scripts that modify and manage the OPC UA address space in real-time. This allows for custom logic to be applied to the address space and enables advanced use cases such as data filtering, data transformations, and custom data processing.

Address Space Management

In traditional OPC UA systems, the Address Space Management is responsible for managing the nodes, references, and attributes in the address space. With Node4i, the Address Space Management has been modified to support advanced features such as real-time data updates and historical data retrieval.

By utilizing the OPC UA MILO SDK, Node4i is able to handle and manage the OPC UA address space in real-time, providing a scalable and efficient solution for industrial automation data management. The integration of Redis-Search and the Lua Script Engine provides advanced features and capabilities, allowing Node4i to meet the demands of modern industrial automation systems.

The integration of Redis-Search and Lua Script Engine in Node4i provides several benefits in handling the OPC UA address space:

• Optimization: By using Redis-Search, Node4i can quickly search and retrieve data from the OPC UA address space, resulting in improved performance and faster data access.

• Monitoring: The integration of Redis-Search allows Node4i to monitor the OPC UA address space in real-time, providing a better understanding of the data flow and enabling users to make informed decisions based on real-time data.

• Improved Scalability: Redis-Search is highly scalable and can handle large amounts of data, making it ideal for industrial applications where large amounts of data need to be processed.

• Better Data Management: The use of Redis-Search in Node4i enables better data management by providing a centralized database for data storage and retrieval, improving data accuracy and consistency.

• Customizable: The integration of Lua Script Engine in Node4i allows for customization of the OPC UA address space to meet specific industrial requirements. This flexibility enables users to tailor the solution to their specific needs and optimize their processes.

• Efficient Data Processing: The use of Lua Script Engine in Node4i enables efficient data processing by providing a lightweight and fast scripting engine, resulting in improved overall system performance.

In conclusion, the Node4i platform provides a comprehensive solution for OPC UA address space management, offering advanced features such as real-time data updates, historical data retrieval, and customization through the Lua Script Engine. With its optimized and monitorized approach, Node4i is well-suited for use in industrial automation systems and the IIoT.
