 Problems in connecting OPC-Server with LabVIEW 5.1.1

I use DataSocket to connect to a OPC-Server. With the "Select-VI" I
choose an item and try to open it with the "Open-VI". In the "Open-VI"
the following error occurse:
"Can't add item to OPC-Group" (0xC0040007).

Is there somebody how has some experience on this??

Does anyone know if I need some update, patch, service pack , AddIn or
something else.

Best regards and in hopping for a answer

There are two things that you can try on labview side.
- In the DataSocket Open Connection VI use Read instead of
ReadAutoUpdate. If your OPC server does not support asynchronous I/O,
ReadAutoUpdate will fail.
- Upgrade your DataSocket by upgrading LabVIEW. The newer DataSocket
handles these low level operations much better. DataSocket 3.0 should
fix this problem.
