April,

Thanks for your reply. But the issue is that we have done what is given in the link that you have suggested. But we are unable to sort out this issue. The dll was custom made one by one of our clients, which they want to use in one of their projects that we are doing.

We are using WinCC6.2 for our project.

Do we have to use any additional license or any additional options have to be installed in WinCC6.2
