Hi, I need some help on OPC and Python (using makepy and Matrikon simulator). I am getting an error when trying to AddItem. The error is: The item definition doesn't conform to the server's syntax. OPC_E_INVALIDITEMID 0xC0040008L
Any idea ? Thanks Here the code: >>> import win32com.client >>> opcserver=win32com.client.Dispatch('OPC.Automation.1') >>> opcserver.Connect('Matrikon.OPC.Simulation.1') >>> groups=opcserver.OPCGroups >>> group=groups.Add('Group1') >>> items=group.OPCItems >>> item=items.AddItem('File1.item1',1) >>> item=items.AddItem('File1.item1',1) Traceback (most recent call last): File "<interactive input>", line 1, in <module> File "<COMObject <unknown>>", line 3, in AddItem com_error: (-2147352567, 'Exception occurred.', (0, None, None, None, 0, -1073479672), None) -- View this message in context: http://www.nabble.com/problem-accessing-OPC-clients-from-thread-tp14111917p15012041.html Sent from the Python - python-win32 mailing list archive at Nabble.com. _______________________________________________ python-win32 mailing list python-win32@python.org http://mail.python.org/mailman/listinfo/python-win32
