ARDI can connect to OPC-UA clients using the new OPCUA driver.

Note that OPC-UA is only a live driver. Historical data access is not currently available.

Performance Note

The driver does take a while to establish the initial connection - it takes some time to get the node IDs for thousands of points of data.

However once connection is established, the driver works extremely quickly.
