Problem with WinCC and S595U

Hello,

I have one big problem.
I'm replacing old SCADA(FIX32) wih WinCC 6.2. There are 8 PLC's,5 of them are S5-95U, 2 areS5115Hand one is S7-300. Protocol is Profibus FDL. In PC is CP5613A2, communication card, which supports FDL protocol.
In PG/PC interface I parameterized Profibus FDL, Profibus - 500k Baudrate in kBaud...., and also in PG/PC interface, inDiagnostics,all PLCs in network are shown (with Profibus addresss).
In the WinCC, there is communcation with S7-300, all tags are displayed in RunTime (in WinCC - added driver isPROFIBUS, under SIMATIC S7 PROTOCOL SUITE), but S5 communcation is not established(in WinCC - added driver isFDL (5412/A2-1), under SIMATIC S5 PROFIBUS FDL), S5 tags are not displayed.

Is it a problem with driver? I have CP5613A2, added driver is FDL (5412/A2-1).
Can you tell me where is the problem?
Is there another way to configure WinCC?
Is it posible that WinCC can't communicate with different drivers at the same time?
Job is to just replace old SCADA with WinCC, so I need to configure WinCC side. PLC's side is OK, and is good parameterized.
