Interfaces
CPU Interfaces
The figure below shows the interfaces of the CPU 41x-2 PCI:
•
PROFIBUS DP interface
The CPU 41x-2 PCI has an integrated PROFIBUS DP interface. You can use
this interface to connect distributed I/O.
The CPU 41x-2 PCI can be operated as a DP master or DP slave on
PROFIBUS DP.
•
MPI/PROFIBUS DP interface
You can use the MPI/PROFIBUS DP interface either as an MPI interface or as
a PROFIBUS DP interface (default: MPI interface).
The multipoint interface (MPI) of the CPU 41x-2 PCI is used to connect to an
MPI subnet or for direct connection of an OP or a PC or programming device
with STEP 7.
The MPI interface can also be parameterized as a DP interface. For this
purpose, you can use SIMATIC Manager in STEP 7 to reassign the MPI
interface. Here, you can configure a DP line with a maximum of 32 DP slaves.
The boundary conditions of the PROFIBUS DP interface are applicable (see
above).
