Connecting
Via the MPI/DP interface, you can connect your PC to
S MPI networks (S7-200, S7-300, and S7-400) or
S PROFIBUS DP networks (DP components).
MPI/PROFIBUS Network
Up to 32 devices (PC, programming device, or programmable controller) can be
connected to the MPI/DP interface to form a network segment. The physical
connection to the MPI/PROFIBUS DP network is via a floating RS485 interface
which is a component of the PC basic module.
Several MPI/PROFIBUS DP network segments can be connected via repeaters.
The complete MPI/PROFIBUS DP network can comprise up to 127 stations. Data
transmission rates from 9.6 Kbps to 12 Mbps are possible in the
PROFIBUS DP MPI network.
Note
You will find more information on setting up an MPI/DP network in the manual
"PROFIBUS Networks" Order No.: 6GK 1970-5CA10-0AA0 or in SIMATIC NET.
