I'm using LV 8.5 with the DSC module. Within a project explorer I define an OPC IO server with few tags and then I bound that tags to define the relative shared variables. If I drag and drop them directly to the front pannel of a blank VI, they work fine. If I drag and drop the shared variables to the block diagram of the same VI I get the following error
Error -1950679020 occurred at Shared Variable Read in Untitled 2
Possible reason(s):
LabVIEW: (Hex 0x8BBB0014) Read access is denied to the shared variable.
This warning occurred while reading \\My Computer\IO_OPC_Test_Shared\Random (\\192.168.10.140\IO_OPC_Test_Shared\Random)
The shared variables are well deployed otherwise they could not work with the fron panel.
Where am I wrong ?
Thank you a lot for the help

Hi Gaetano!
This is a know issue of LabVIEW 8.5.
Here you can find the description and the workaround (look on the page for the error code 1950679020).
Have a nice day
