Configurations Using a PC with an MPI or CP Card: Multiple-Master Network

Many configurations are possible when you use a multipoint interface card or
communications processor card. Either card provides a single RS-485 port for
connection to the network using an MPI cable. You can have a station running the
STEP 7-Micro/WIN 32 programming software (PC with MPI or CP card, or a
SIMATIC programming device) connected to a network that includes several
master devices. (This is also true of the PC/PPI cable if you have enabled multiple
masters.) These master devices include operator panels and text displays (TD 200
units). Figure 7-9 shows a configuration with two TD 200 units added to the
network.
