Prosys OPC UA Browser

Prosys OPC UA Browser is a generic client that connects to any OPC UA server, allowing users to explore the server’s address space, read and write variable values, invoke methods, and monitor data changes, events, and alarms. It presents the information through a web‑browser‑like graphical interface, supporting multiple simultaneous server connections and providing views for attributes, references, and historical data.

The tool includes a Data View for real‑time monitoring, trend graph visualization, and optional logging to files. Its History View can retrieve and display variable histories, applying OPC UA aggregate functions such as daily averages or weekly minima and maxima. An Event View lets users watch server events, acknowledge or confirm alarms, and access event history.

Security features cover all OPC UA security modes, policies, and authentication methods. The application also supports PubSub connections, showing MQTT topics, publishers, and DataSetWriters, with capabilities for data visualization and message logging. It runs on Windows, Linux, and macOS.
