Issue Details

I need to interface LabVIEW share variable with 3rd party SCADA software via OPC DA. NI Variable Engine will act as OPC DA and I need the CLSID key number to configure in my SCADA software, where I can find the CLSID key number for NI Variable Engine? 


You can open the Registry Editor and find the CLSID key number from the path below:

Computer\HKEY_CLASSES_ROOT\National Instruments.Variable Engine.1\CLSID
