3.12 Connecting the Field PG to a SIMATIC S7 Network
(MPI/DP)
Connecting an S7 Programmable Controller via an MPI/DP Interface
You can use the potential-separated*) MPI/DP interface to connect the SIMATIC
Field PG to a SIMATIC S7 programmable controller or to a PROFIBUS network.
The MPI patch cord (5m) for connecting to SIMATIC S7-CPUs (Order no.:
6ES7901-0BF00-0AA0) is included in the consignment. The data transfer rate is
limited to 187.5 Kbit/s when using this patch cord. For baud rates > 1.5 Mbit/s you
must use a PROFIBUS cable for 12 Mbit/s (Order no. 6ES7901-4BD00-0XA0).

MPI/DP interface
Fig. 3-12 Connection Using the MPI/DP Interface
Proceed as follows when connecting to a SIMATIC S7 programmable logic
controller:
1. Switch off your device.
2. Open the interface cover on the left-hand side panel of the device.
3. Connect the cable to the MPI/DP interface.
Caution
Before plugging in the cables, the static charge on your body, the unit, and the
cables must be equalized. You can do this by briefly touching the metal mounting
plate for the interfaces on the rear panel.
*) Electrical isolation in the safety extra-low voltage circuit (SELV circuit).
