Typical Profibus Dp Network Structure - Siemens SIMATIC ET 200S Manual

Structure of a PROFIBUS DP network
The figure below illustrates a typical PROFIBUS DP network structure. The DP
masters are integrated into the relevant device -- for example, the S7 400 has a
PROFIBUS DP interface and the IM 308-C is inserted in an S5-115U. The DP
slaves are the distributed I/O systems connected to the DP masters by
PROFIBUS DP.
