Hi,

i have write some lines of code to read a variable but i don't understand whta value i have to set for the Attribute, i have tried whit the name of the variable but nothing, this is the code:

Private client As EasyUAClient

Private value As Object



Private Sub Button2_Click_1(sender As Object, e As EventArgs) Handles Button2.Click

Dim COMUNICATIONOPCUA As String

Dim ATTRIBUTE As UAAttributeId



COMINCAZIONEOPCUA = "opc.tcp://192.168.1.251:4840"

ATTRIBUTE = 1

value = client.ReadValue(COUNICATIONOPCUA, ATTRIBUTE)



End Sub
