Using WinCC to export data to Access database


Thread Starter


To convert data from WinCC to Access, I want to know how to Link Topic and Link Item in Visual Basic. I use Visual Basic.

Thanks in advance!
the method you are proposing will use DDE which is now pretty much obsolete.

instead ...

if you are looking to access real-time data then you should use OPC (there is an example script in the WinCC manual on how to do this from Excel and can be easily adapted for use in VB)

if you want to access WinCC' historical data then there are plenty of methods and examples on the WinCC support site, in the WinCC Knowledge Base CD and at

hope this helps
