3.7 Connecting PROFIBUS/MPI
SIMOTION D4x5-2
70 Commissioning and Hardware Installation Manual, 02/2012
When communicating with XSEND/XRECEIVE, there is no need to configure the connection
in NetPro. XSEND/XRECEIVE can be used via PROFIBUS or MPI.
Via PROFIBUS: For communication between SIMOTION devices
Via MPI: For communication between SIMOTION and SIMATIC S7 devices
The SIMOTION interface must be connected to the MPI interface of the SIMATIC S7
devices. Connection via PROFIBUS is not possible.
The baud rate of the SIMATIC S7 device must be set at the SIMOTION interface (see
documentation for the relevant SIMATIC S7 devices).
Operate MPI like PROFIBUS
The information on wiring the connector (terminating resistors) and the rules for routing of
cables for PROFIBUS apply to this interface as well. When carrying out this procedure,
consult the relevant references.
Connector features
The bus connector is used to connect the MPI bus cable to the MPI interface (X136). This
enables you to establish connections to additional nodes (e.g. PG or SIMATIC S7-CPU).
Only bus connectors with a 35° cable outlet should be used in order to ensure that the front
cover can be closed.

Available spare parts and accessories.
MPI bus cable
The PROFIBUS cable specifications apply here as well;
Please note the relevant information on setting up an MPI network.
Setting up an MPI network
Keep in mind the following basic rules when setting up an MPI network:
When using the interface as an MPI interface, it is not possible to arrange additional
control for a drive in isochronous mode or to connect distributed I/Os to this interface.
An MPI bus line must be terminated at both ends. This is achieved by activating the
terminating resistor in the MPI connector in the first and last station and deactivating the
other terminating resistors.
At least one terminator must be supplied with 5 V.
This means that an MPI connector with an activated terminating resistor must be
connected to a device that is switched on.
Spur lines (cables leading from the bus segment to the station) should be as short as
possible, that is, < 5 m in length. Unused spur lines should be removed wherever
possible.
