7.2 System changes during operation

Configuring
You configure the following:
● Bus link on PROFIBUS DP
During configuration, the couplers for the FF segment are always part of the bus link.
● FF devices on FF segment (FF subsystem in HW Config)
The necessary configuration steps are described in section "How to prepare a FOUNDATION
Fieldbus for FF devices (Page 27)".
S7-400H as DP master
The following AS components operate as DP master:
● CP 443-5 ext.
● PROFIBUS DP connection of the CPU
The following requirements are met for the DP master systems:
● The DP masters process the same user program.
● The DP masters have the same parameter assignment and configuration for the interface
modules.
