OpcUaClient

Description

The OpcUaClient object is a container object for all OPC UA related objects. It is required to directly instantiate objects from the Qt OPC UA QML module. Alternatively these objects can be used as properties within any InCore object.

› Inherits:: Object

Overview

Properties

Methods

Signals

Properties

objects

This property holds a list of OPC UA related objects, such as OpcUaClientConnection.

› Type:: List<Object>
› Signal:: objectsChanged()
› Attributes:: Readonly

Methods

fullNodePath(OpcUaNodeIdType nodeId)

This method returns the full node path, i.e. namespace + identifier of the given node ID.

This method was introduced in InCore 2.6.

› Returns:: String

Signals

objectsDataChanged(SignedInteger index)

This signal is emitted whenever the List.dataChanged() signal is emitted, i.e. the item at index in the objects list itself emitted the dataChanged() signal.

import InCore.OpcUa 2.5

Application {
    OpcUaClient {
        OpcUaClientConnection {
            // ...

            identifier: "s=Machine"
            ns: "Example Namespace"

            onValueChanged: console.log("Example value", value)
        }
