I wrote a basic web app to communicate with the opc server. I am able to connect to the server, but i can't get the value from opc, i am not sure what to fill in the serverhandle. and from the specs, the example uses SET, which doesn't exist anymore in the asp and vb.net. what should i replace it with?
TextBox2.Text = ConnectedGroup.OPCItems.GetOPCItem(serverhandle)
Below is the specs example for OPC.
Dim AnOPCItem as OPCItem
Dim Source as Integer
Dim Value as Variant
Dim Quality as Variant
Dim TimeStamp as Variant
'process the values
