About
Prosys OPC UA Browser is a generic OPC UA client that can connect to any OPC UA server. You can connect to several servers at the same time, browse the server address space, read and write data, and call methods. You can also monitor data changes and events, acknowledge and confirm alarms, and read data change and event histories from the server. The application is available for macOS, Windows, and Linux.
The Data View lets you read and write variable values and monitor them for changes, and a trend graph can visualize those changes. The Data Logger records data changes to a file. The History View reads variable histories and shows them in a graph, and it can request aggregated data, such as daily averages, using the aggregate functions the server supports. The Event View monitors server events, including alarms and conditions, and lets you choose which fields to monitor. The Event History View reads event histories from the server.
Prosys OPC UA Browser supports all OPC UA security modes and policies, including different user authentication methods. It also provides PubSub connections, which can display available MQTT topics, publishers, and DataSetWriters, monitor data changes and events, and log messages.
