Structure of a PROFIBUS DP network
The figure below illustrates a typical PROFIBUS DP network structure. The DP masters are
integrated in the respective device, e.g. if the S7-400 has a PROFIBUS DP interface, the
master connection IM 308-C is connected with an S5-115U. The DP slaves are the distributed
I/O devices that are linked with the DP masters via the PROFIBUS DP.
