MPI/PROFIBUS DP
Up to 32 devices (PC, programming device or programmable controller) can
Network
be connected to the MPI/DP interface to form a network segment. The
physical coupling 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 coupled 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 12 Mbps are possible in the PROFIBUS
DP via the MPI/DP interface.
Note
You can find information on establishment of an MPI/DP network in the
Manual "Setting up an S7-300", Order No.: 6ES 7030-0AA00-8BA0.
In order to be able to use the MPI/DP interface, the port must be enabled in
the BIOS SETUP program in the submenu "Hardware Options."
The MPI/DP interface does not occupy any hardware resources if it is
disabled.
The interface has "Plug and Play" capability. This means that the necessary
resources are managed by the PCI Plug and Play mechanism of the BIOS.
