Structure of a PROFIBUS-DP Network
The figure below shows you a typical PROFIBUS-DP network configuration. The
DP masters are integrated in the relevant device – for example, the S7-400 has a
PROFIBUS-DP interface, and the IM 308-C master interface module is inserted in
the S5-115U. The DP slaves are the distributed I/O devices connected to the DP
masters via PROFIBUS-DP.
