OPCSiemensDAAutomation???

Question

Hi,

I have to support a project with MS Visual Basic 2008 Express and Siemens S7 PLC.
The Visual Basic needs a reference to OPCSiemensDAAutomation, but I can not find out
if this belongs to the Visual Basic package (if so, which version?)
or to a Siemens software package (which).
Please tell me what I need.

Answer 1

Got some more info: OPCSiemensDAAutomation
may be part of the Professional version of the MS Visual Basic 2008.
