Structure of a PROFIBUS-DP network
The figure below shows you a typical PROFIBUS DP network structure. The DP
masters are integrated in the corresponding unit, e.g. the S7-400 or S7-300 is
equipped with a PROFIBUS-DP interface. The DP slaves, namely the distributed
I/O, are interconnected to the DP masters via PROFIBUS DP.
