Real problem with time synchronization

I want my WinCC station to synchronize its time according to PLC. So that's what I've done: 1. In CPU set it as "PLC as master" 2. In CP343-1 set it to forward frames (I had no possibility to check "station to LAN" option) 3. In WinCC Time Synchronization manager I set it as slave and ethernet card on ISO protocol. Nothing happened. No time is synchronized. I have some clues by myself, but can't fully test it: 1. I use "regular" ethernet card and Softnet-IE Lean driver 2. I use CP343-1 for this. Maybe I need "Advanced" ? Has anyone ideas on this ? Thanks in advance.
	Best regards, Darius

So if some one need to do something like this, they should look this thread. It would be nice if moderators set this thread as tip.
