Up to 32 devices (PC, programming device, or programmable controller) can be connected to the PROFIBUS/MPI interface to form a network segment. The physi- cal connection to the network is via a floating RS485 interface which is a compo- nent of the PC basic module.

Several network segments can be connected via repeaters. The complete network can comprise up to 127 stations. Data transmission rates from 9.6 Kbps to
