OPC Toolbox™ provides an OPC UA client to connect to OPC UA servers. Using the client, you connect to the server, query server status, browse the server namespace, read and write current values, and read historical values from nodes on the server. Historical data is retrieved as OPC data objects, which allow you to process historical data in preparation for common analysis tasks.
