Automa OPC-UAC simplifies OPC UA (Open Platform Communications Unified Architecture) connectivity for Microsoft Windows applications, requiring fewer than ten function calls to establish communication. It links SCADA (Supervisory Control and Data Acquisition) and HMI (Human-Machine Interface) systems with MES (Manufacturing Execution Systems), facilitating real-time data exchange, precise timestamp tracking, and data quality management. With built-in DataChange Subscribers, developers can monitor industrial processes in real time. Multi-language support (C++, C#, VB) ensures flexibility for diverse development environments, making it an efficient tool for automation and machine-to-machine communication.

The OPC-UAC v2.0 update adds built-in support for user authentication through usernames and passwords. This enhancement aligns with standard OPC UA security practices, providing a straightforward way to enforce access control when connecting to servers. It helps developers and system administrators maintain secure communications across industrial systems that require user-level verification.
