Multiplatform graphical user interface to view data from any OPC UA server.

Prosys OPC UA Client is a generic OPC UA Client application supporting all main OPC UA information models. Browse address space, select nodes and read and write data. Access nodes that contain historical data and use trend charts to illustrate the data. Subscribe to events and alarms from the desired node and acknowledge and confirm alarms.

Data Access

With OPC UA Client you can manage multiple server sessions at once by tabbed pages. For secure connections OPC UA Client supports full security features defined in OPC UA specification: signing and encrypting messages with 128 or 256 bit key, and authenticating clients by user name and password or certificates and private keys. Connecting to server is based on server URL, but OPC UA Client also supports discovery.

Server address space is illustrated using a tree structure that can be used for browsing the nodes. Nodes can be picked from tree to monitored item list, in which it is possible to view node attributes and read and write variable values. In addition to the attributes presented in the monitored item list, there is a view for illustrating all the attributes and references of the node selected in the tree.

Historical Access

Using OPC UA Client you can access nodes that contain historical data and use graphical drawing tools to illustrate the data. You can set the charted time span, chart several nodes at once and perform basic actions for the chart, like zooming, saving or printing it. Historical access functions can be found under History View tab.

Alarms & Conditions

Under Event View tab you can subscribe to events and alarms from the desired node of the server. You can customize the view freely and select what event or alarm information you would like to see in the event list. It is also possible to acknowledge and confirm alarms.
