Siemens SIMATIC S7-300 CPU Data: CPU 315-T-2 DP User Manual

Setting up an S7-300 with a Technology CPU
4.4 Subnets
4.4.2 Interfaces
MPI/DP interface
You can reconfigure this interface in STEP 7 as a PROFIBUS DP interface.
The MPI (Multi-Point Interface) represents the CPU interface for PG/OP connections, or for
communication on an MPI subnet.
The PROFIBUS DP interface is mainly used to connect distributed I/O. PROFIBUS DP
allows you to create large subnets, for example.
