Example

import InCore.Foundation 2.5
import InCore.OpcUa 2.5

Application {
    OpcUaClient {
        OpcUaClientConnection {
            // ...
        }

        OpcUaClientNodeId {
            identifier: "s=Machine"
            ns: "Example Namespace"
            id: machineNodeId
        }

        OpcUaClientValueNode {
            nodeId: OpcUaClientRelativeNodeId {
                startNode: machineNodeId
                path: [ OpcUaClientRelativeNodePath { ns: "Example Namespace"; browseName: "Example Value" } ]
            }
            onValueChanged: console.log("Example value", value)
        }
