Networking the Box PC on PROFIBUS
PROFIBUS is an open and robust bus system for industrial use. It can be used to
configure networks with up to 32 stations per segment. PROFIBUS-DP supports
data-transfer rates from 9.6 Kbaud to 12 Mbaud.
How the Network Functions
The network operates on the master-slave principle with token passing (complying
with DIN19245, PROFIBUS). It distinguishes between active and passive stations.
An active station receives the token and passes it on to the next station within a
specified time.

Using the following components, for example, you can connect or network the
SIMATIC Box PC 620 with PROFIBUS:
S RS 485 MPI/DP interface adapter (Optional product feature)
