PROFIBUS

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.

Hardware Requirements

Using the following components, for example, you can connect or network the SIMATIC Box PC 620 with PROFIBUS:

SRS 485 MPI/DP interface adapter (Optional product feature)

SShielded, twisted pair (bus cable or connecting cable to network).
