writing status to PLC

Hi,
I was able to associate status of DO on my PLC via OPC connection. I could use your help on how to write (i mean change) status to my plc. Should I write a script or can i somehow do this through OPC server? Could you give me an example of how to achieve this?
Thanxs in advance!

Insert Toggle Button, and in Click event add «OnClick» callback.Then add code:

 # Arguments: Object sender, EventArgs e
 def OnClick(sender, e):
	if sender.IsChecked == False:
		Application.GetChannel("opc_connection_plug.BooleanTag").Value = False
	else:
		Application.GetChannel("opc_connection_plug.BooleanTag").Value = True


Worked like charm for me.
