3.13 Networking the Field PG P4 with Other Stations on
PROFIBUS
Networking the SIMATIC Field PG P4 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 Field PG P4 with PROFIBUS:
• RS 485 MPI/DP interface adapter, integrated
• Shielded, twisted pair (bus cable or connecting cable to network).
