UAClient

UAClient refers to a software component or library that implements the client-side functionality of the OPC Unified Architecture (OPC UA) standard. OPC UA is a platform-independent, service-oriented architecture for industrial automation that enables interoperability between different systems and devices. A UAClient is responsible for establishing a connection to an OPC UA server, browsing its address space to discover available data points and methods, reading and writing data values, subscribing to data changes, and invoking methods.

UAClient implementations can vary in their complexity and feature set. Some are simple libraries that provide basic read/write and subscription capabilities, while others are more comprehensive applications or toolkits that offer advanced functionalities like security management, user authentication, and complex data type handling. Developers often use UAClient libraries to integrate devices, SCADA systems, historians, and other industrial automation software with OPC UA enabled servers. This allows for seamless data exchange and control across diverse industrial environments. The implementation of a UAClient adheres to the OPC UA specifications, ensuring compatibility with any compliant OPC UA server.
