Connecting and Switching on the Computing Unit

MPI/PROFIBUS-DP network

Up to 32 devices (PCs, programming units or PLCs) can be connected to the MPI/DP interface to form a network segment. The physical connection to the MPI/PROFIBUS-DP network is via an isolated RS485 interface, which is an integral part of the PC’s basic board.

Several MPI/PROFIBUS-DP network segments can be connected via repeaters. The complete MPI/PROFIBUS-DP network can consist of up to 127 nodes. Data transmission rates of 9.6 Kbits to 12 Mbit/s are possible using the PROFIBUS-DP MPI network.
