My problem is exactly the same problem as already described in:
http://exchange.ni.com/servlet/ProcessRequest?RHIVEID=101&RNAME=ViewQuestion&HOID=5065000000080000000F5D0000&ECategory=LabVIEW.LabVIEW+General
If the computer with the OPC-Server is down, my complete LabView Applicaton hangs in an internal LabView function. I tried already every suggestions from the above mentiond link without any success.
Did NI find a solution for this problem in the last two years?
I attached a small example VI with my OPC Client.
