Simatic net -CP5431 and CP5614 FMS Communication

All Simatic Net experts,
I tried to change our WINCC computers with two new ones. I installed CP5614 card and Simatic 6.0 with windows NT 4.0. I set same Baud Rate, HSA and FMS Bus Parameters as old ones,, the only parameters I am not sure are local and remote LSAP, but the communicaiton with CP5431 is still not working even though others are no problem. Could you tell me what's the problem and how can I fix it?

Thanks

Steve

CP5412 inserted at ISA slot and Simatic Net CD 1997 software installed in old computers. Because it's difficult to find ISA computers now so we ordered 2 new PCI computers and CP5614 Profibus cards. Any suggestions and ideas will be appreciated.

Thanks

Steve
