PG 720 P Programming Device
C79000-G7076-C721-02
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 programming device 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. The data transmission rate in the MPI network is 187.5 Kbps.
Data transmission rates from 9.6 Kbps to 1.5 Mbps are possible in the
PROFIBUS DP via the MPI/DP interface.
Note
You can find information on setting up an MPI/DP network in the manual
