Replied by support on topic Writting in a Arrayvariable with OPC UA

Hello,

writing an array isn't much different from writing a scalar value:

Code:

' This example shows how to write a value into a single node that is an array of Int32.

Imports OpcLabs.EasyOpc.UA
Imports OpcLabs.EasyOpc.UA.OperationModel

Namespace UADocExamples._EasyUAClient
    Partial Friend Class WriteValue
        Public Shared Sub ArrayOfInt32()

            ' Define which server we will work with.
            Dim endpointDescriptor As UAEndpointDescriptor =
                    "opc.tcp://opcua.demo-this.com:51210/UA/SampleServer"
            ' or "http://opcua.demo-this.com:51211/UA/SampleServer" (not in .NET Standard)
            ' or "https://opcua.demo-this.com:51212/UA/SampleServer/"

            ' Instantiate the client object
            Dim client = New EasyUAClient()

            ' Modify value of a node
            Try
                ' // /Data.Static.Array.Int32Value
                Dim arrayValue = New Int32() {11111, 22222, 33333, 44444, 55555, 66666, 77777}
                client.WriteValue(endpointDescriptor, "nsu=http://test.org/UA/Data/ ;i=10305", arrayValue)
            Catch uaException As UAException
                Console.WriteLine("*** Failure: {0}", uaException.GetBaseException.Message)
                Exit Sub
            End Try
        End Sub
    End Class
End Namespace

Best regards

Writting in a Arrayvariable with OPC UA was created by Nordmann447

HI,
i tried to write into a Arrayvariable but i cant find the correct Code in the discription.

Reading a array was not a Problem, i write something like that:

Dim Variable As UAAttributeData = EasyUAClient1.Read(KommunikationServer, NoteID())
lable1.text = Variable.value(5)

Do you have a simply Code to write in a Arrayvariable?
