Example of an MPI network

Hardware prerequisites in the PD/OP for accessing the ET 200S
Before you can access an IM 151-7 CPU from a PD/OP, the PD/OP must fulfill the
following requirements:
S it must have an integrated MPI interface or MPI card or
S it must have an integrated PROFIBUS-DP interface or DP card.
Transmission rates
In the MPI network, all MPI transmission rates are possible with the IM 151-7 CPU.
Network components
You configure an MPI network using the same network components as those used
for a PROFIBUS-DP network (see Section 4.2).
Maximum data transfer rate and cable length with a PD connecting cable
You can obtain a maximum data transfer rate of 1.5 Mbaud using the PD
connecting cable. The cable length may not exceed 3 meters.
The PD connecting cable should only be connected for an extended period of time
during startup and service.
Data transfer rates over 1.5 MBaud require an active connecting cable for the PD
connection (order number: 6ES7 901-4BD00-0XA0).
