I browsed the CD that was supplied in the course that I took a couple of weeks ago. Much to my dismay, it was a lot of AVI files, about 16Meg each. They do go through how to create scripts and such, but do not go into detail about how to write vba-excel scripting, just how to start the process.
I asked the instructor if there were examples of the script writing on the CD, and he said yes. Obiously, he didn't know.
The course/or info seminar was available to all Siemens suppliers. I would call Siemens and ask about the WinCC Flex Seminar information that would be available to end users.
I bought the WinCC Flex STD for $495.00CAD. Unbeleivable price. The advanced was not priced, but give Siemens Help a call and find out about the documentation supplied.
Sorry for the misleading information, I could post the AVI's, but they are quite large.
