What is OPC UA:

OPC UA stands for OPC Unified Architecture. It is an industrial automation communication standard published by the OPC Foundation in 2008. OPC UA (Object Linking and Embedding for Process Control Unified Architecture) is a communication protocol and data exchange standard for industrial automation and control systems. Its main purpose is to enable interoperability between different devices, machines, and systems in order to effectively share data and information in industrial environments.

The advantages of OPC UA include:

Open standards: OPC UA standards are freely available for anyone to use. There are no licensing fees or other restrictions for implementing OPC UA devices or systems.

Cross-platform: OPC UA is not limited to any specific operating system or programming language. It can be used on a variety of platforms and systems.

Reliability: OPC UA provides reliable communication, even in unstable network conditions.

Unified architecture: OPC UA provides a unified architecture for communication, data modeling, and security, which enables devices and applications from different vendors to interoperate.

Security: OPC UA supports a variety of security mechanisms, including encryption, authentication, and authorization, to ensure the confidentiality and integrity of data during transmission.

Efficient data transmission: OPC UA uses binary encoding to achieve efficient data transmission, which is important for real-time control applications and the transmission of large amounts of data.

Flexible data model: OPC UA defines a flexible data model that can describe a variety of different types of data, including real-time data, configuration information, and metadata.

Platform independence: OPC UA supports a variety of different platforms, including Windows, Linux, and embedded systems. This enables interoperability in a variety of different environments.

Extensibility: OPC UA supports extensibility, allowing custom features and data types to be added to meet the needs of specific applications.

OPC UA has a wide range of applications, including:

Industrial control: OPC UA can be used to control the operation of industrial equipment, such as starting, stopping, and adjusting parameters.

Industrial Internet of Things (IIoT): OPC UA can be used for Industrial Internet of Things (IoT) applications, such as remote monitoring and data analysis.

In industrial monitoring systems, OPC UA can be used to collect data from different industrial devices into a central monitoring system for monitoring and analysis, such as temperature, pressure, and flow.

In industrial IoT applications, OPC UA can be used to transmit data from industrial devices to the cloud for data analysis and applications.

OPC UA is a rapidly developing industrial automation communication standard with a wide range of applications. With the development of industrial IoT, OPC UA will play an increasingly important role in the industrial automation field.

AIC OpcUa Extender Server is an OPC UA server suite that focuses on data collection communication with systems. Based on the OPC UA communication model, we provide the required data collection platform, allowing users to use the service-oriented architecture of OPC UA to organize their complex data into OPC UA namespaces. AIC OpcUa Extender Server has features such as tag subscription and real-time updates. As a communication gateway, it plays an important role in allowing OPC UA clients to operate HMI or PLC data. AIC OpcUa Extender Server includes a configurable GUI for parameters and settings, as well as an OPC UA server service as the center of data collection and sending to OPC UA client applications, thus realizing simplified OPC UA system operation.
