Connection
Using the MPI/DP interface, it is possible to connect programming units with:
S MPI networks (S7 200, S7 300 and S7 400) or
S PROFIBUS-DP networks (DP components)
MPI/PROFIBUS-DP network
Up to 32 devices (PCs, programming units or PLCs) can be connected to the
MPI/DP interface to form a network segment. The physical connection to the
MPI/PROFIBUS-DP network is via an isolated RS485 interface, which is an
integral part of the programming unit basic board.
Several MPI/PROFIBUS-DP network segments can be connected via repeaters.
The complete MPI/PROFIBUS-DP network can consist of up to 127 nodes. Data
transfer rates from 9.6 kbps to 12 Mbps are possible on the MPI network
PROFIBUS-DP.
Note
You will find information on configuring an MPI/DP network in the manual Profibus
Networks or SIMATIC NET.
