Additional notes on configuration

Device-specific number of interconnections
The number of interconnections available as Backup Link Master for an FF device is device-
specific.
Make sure that the permissible number of interconnections on the FF segment is not exceeded
during configuration. The configured interconnections are added:
● Interconnections with the process image
● CiF interconnections
You can find additional information about this in the section ""Interconnection Editor" dialog
box (Page 37)"
Capability level
The automation system can only communicate with the device if the capability level of the
device matches the configured capability level.
Changing the configuration
Separating FOUNDATION Fieldbus from PROFIBUS DP
If you separate the interface module for the FOUNDATION Fieldbus from PROFIBUS DP in
HW Config, this has the following effects:
● The bus system is orphaned with all FF devices.
● The FF devices and CiF interconnections will be retained.
● The addresses will be released.
● The interconnections between the FF and the automation system will be retained.
● This bus system is disregarded during compiling and downloading of the automation
system.
Changing interconnections - Impact on communication
● The FF device must be restarted when you change (device-internal) interconnections. The
FF device is not available during the restart period.
Connecting the separated FOUNDATION Fieldbus to an automation system (behind
PROFIBUS DP)
● When you connect an interface module for the FOUNDATION Fieldbus that was separated
from PROFIBUS DP to an automation system (behind PROFIBUS DP), observe the
following:
– Interconnections between the FOUNDATION Fieldbus and the automation system can
