dear sir,

The same problem am facing but the link which they were provided was not working, so please find my following queries

1.To communicate with the foundation field bus the s7300 CPU with dp-ff link is enough or we need to go for s7400 CPU with dp-ff link.

because I found the manual which they are explained in DCS and S7400 but they not provided  about s7300.

Split from Foundation Field Bus communication with S7300 .
