The OPC-UA Connector Extension connects RapidMiner with an OPC-UA server, allowing easy access to machine and sensor data.

The OPC-UA connector utilizes the Eclipse Milo implementation of the OPC-UA specification (version 1.03).

The extension provides a new connection object that stores and validates the connection to an OPC-UA server endpoint.

The extension also adds three new operators to RapidMiner:

Browse Nodes

Returns a list of all nodes connected to a node ID. This can help to identify all sensors linked to an asset.

Read OPC-UA

Can collect new incoming data points from a node for a given period of time.

Read OPC-UA History

Can collect stored data points from a node with the "History Read" property. It's possible to specify the exact time period for the collected data point and also to state an interval to sample only a subset of the recored values.
