Operating The Profibus Interface (X21) As An Mpi Interface - Siemens SIMOTION D410 Commissioning Manual

Parameter assignment / addressing
4.3 Configuring the PROFIBUS DP interface (only D410 DP)
If any change to the DP cycle violates this rule you must also change the SINAMICS cycle
clocks. In order to change the cycles in the Expert list of SIMOTION SCOUT, select the
"Control_Unit" from "SINAMICS_Integrated" in the Project Navigator, and then open the
"Expert List" by selecting the "Expert" command from the shortcut menu.
Example:
A default value of 4 ms is set at the SINAMICS setpoint channel. If the DP cycle is to be set
to 3 ms, the fact that an integer multiple value is required means that you will need to set 3 ms
or 6 ms (for example) for the setpoint channel.
Current controller cycle clock
With the SIMOTION D410, the following current controller cycle clocks p0115[0] are configured
for the SINAMICS Integrated:
● for servo: 125 μs or 250 μs
● for vector: 375 μs (chassis) or 500 μs (PM340).

Operating the PROFIBUS interface (X21) as an MPI interface

The X21 interface can also be operated as an MPI interface instead of a PROFIBUS DP
interface. The typical (default) baud rate is 187.5 Kbaud. A baud rate of up to 12 MBaud can
be set for communication with other CPUs. It should be noted, however, that a rate of 12 MBaud
is not supported by all CPUs (e.g. smaller SIMATIC S7 CPUs).
The following list provides examples of when using MPI (Multi Point Interface) may prove
effective:
● If a PC/PG is being used with an MPI interface
● If an OP/TP only has an MPI interface (newer devices have PROFIBUS or PROFINET
● If SIMOTION and SIMATIC CPUs are coupled via XSEND/XRECEIVE
