OPC UA Client library for Windows applications.
OPC-UAC is a client library for Windows applications that need to interact with OPC Unified Architecture (OPC UA) servers. It provides a straightforward interface for reading and writing variable values and monitoring changes. Developers can integrate industrial data communication into C, C++, C#, or Visual Basic applications while handling connections and subscriptions through configurable settings.

OPC UA Client Library For Windows Applications

OPC-UAC provides a client-side library that allows Windows applications to connect to OPC Unified Architecture servers. It enables software systems to exchange data with industrial equipment and automation platforms that expose information through OPC UA communication interfaces.

Support For Read Write And Data Monitoring Operations

The library exposes functions that allow applications to read variable values, write data to server nodes, and monitor changes in real time. This allows production management systems and other industrial software to react to process events and updated device information.

Simple Programming Interface For Application Integration

OPC-UAC provides a straightforward programming interface that simplifies integration with existing software projects. Developers can implement OPC UA communication features without building their own protocol stack, reducing the complexity of connecting applications to automation devices.

Configuration-Based Connection And Subscription Management

Connections, monitored items, and subscriptions can be defined through configuration files. This approach allows developers to manage server connections and data items outside the application code while maintaining consistent communication settings across deployments.

Server Discovery And Item Browsing Capabilities

The included configuration environment supports OPC UA server discovery and browsing of the available address space. Developers can explore the structure of data exposed by servers and select the required items for reading, writing, or monitoring operations.

Alias-Based Identification Of Data Items

OPC-UAC allows items to be referenced through alias names instead of direct node identifiers. This abstraction simplifies application code and hides protocol-specific node identifiers, making it easier to maintain and update data mappings in industrial software.

Communication With Multiple OPC UA Servers

Applications using the library can connect to multiple OPC UA servers within the same network environment. This allows a single application to collect and manage information from multiple automation devices, controllers, or industrial software systems.

Compatibility With Multiple Programming Environments

The library can be integrated into projects developed in languages such as C, C++, C#, and Visual Basic. This enables developers working with different Windows development environments to implement OPC UA client communication within their applications.

Integration For Industrial Automation Systems

OPC-UAC enables applications such as MES, SCADA extensions, and production management systems to exchange data with automation infrastructure. Through OPC UA communication, applications can interact with PLCs, machines, and industrial platforms connected to the network.
