Why does the WinCC Connection String Inspector in the AS Node Type Wizard of PCS 7/OPEN OS show an empty window?

  • Entry
  • Associated product(s)
Opening the WinCC Connection String Inspector in the AS Node Type Wizard shows an empty window, although there are connections defined in the WinCC project opened in the background.

This information is important for integrating 3rd Party Systems with PCS 7/OPEN OS V8.2 directly without OPC.
The proper connection string with the Initial Parameters cannot be retrieved.
For resolving this issue please install Microsoft SQL Server Native Client V10.0.
