Figure 4-7 Connection to a redundant PROFIBUS DP
Transmission rate
You have two interconnection options for the gateway between PROFIBUS DP and
FOUNDATION Fieldbus . These result in different transmission rates on PROFIBUS DP.
● If you connect via a bus link, a transmission rate of up to 12 Mbps is possible on PROFIBUS
DP.
● The transmission speed on the FOUNDATION Fieldbus is 31.25 Kbps.
Availability - high availability interfacing
In a redundant system, we recommend that you implement the interface to PROFIBUS DP
redundantly (redundant bus link).
