Requirements for the COM Manager

Requirements

  • Windows operating system.

  • Correctly installed WinCC OA version.

  • Reference to WCCOACom 1.0 Type Library (located in <wincc_oa_path>/bin/windows/WCCOAcom.dll). Only if the Excel Report add-on is selected in the WinCC OA setup, the "windows" folder will be created andWCCOAcom.dllwill be registered automatically. The methods of the COM Manager were defined in the WinCC OA class library. The class library is located in the object library COMMANLib. You have to refer to the COMMANLib (WCCOACom 1.0 Type Library) in the project so that the methods can be used (for example, with the Visual Basic editor in Excel the reference is executed via the menu item Extras > References...).

Note:

Also dyn_dyn arrays (2 Dim arrays) (int/float/string) are supported for COM methods, for example,

 dyn_dyn_float data;
for(int i = 1; i <= 20; i++)
  for(int j = 1; j <= 20; j++)
    data[i][j] = FunctionSin(i*0.314);
CWGraph3D.Plot3DSimpleSurface(data);

For the system there are no special requirements concerning the central memory and fixed disk storage.

Note:

The COM Manager is not a console application (this means that the manager cannot be added to the console like the other managers - see manager administration). The methods of the class library WCCOACom 1.0 Type Library should be used for the manager (see also ComManager object).
