[?]: Profibus network problem with SCADA Wonderware InTouch

[kelertas]

hello,

I need help about profibus network.
My PB network structure is:

SCADA1 and SCADA2. It is a PC's with Woodhead PB card inside. My SCADA is Wonderware InTouch.
PLC1 is S7-314C-2 DP.
PLC2 is S7-314C-2 PtP with CP 342-5.
PLC3 is S7-314C-2 DP

The problem problem is that at the moment from SCADA1 and SCADA2 I can exchange data just with two of three my PLC's.
i.e., with PLC1 and PLC2, or if I disconnect PLC2 from PB network then with PLC1 and PLC3.

Thanks in advance.
