The object sequence for process data exchange via IF2 depends on the object sequence
from IF1; see "List of drive objects" (p0978).
The factory setting of p8839[0,1] =99 enables the implicit assignment (see table above).
An alarm is generated in case of invalid or inconsistent parameterization of the assignment.
Parameters for IF2
The following parameters are available in order to optimize the IF2 for a PROFIBUS or
PROFINET interface:
● Receive and send process data:
r8850, p8851, r8853, r8860, p8861, r8863
● Diagnostic parameters:
r8874, r8875, r8876
● Binector-connector converters:
p8880, p8881, p8882, p8883, p8884, r8889
● Connector-binector converters:
r8894, r8895, p8898, p8899
Significance of 88xx identical to 20xx

Note
Using the HW Config configuration tool, a PROFIBUS/PROFINET slave with two interfaces
cannot be shown. In parallel operation, this is the reason that SINAMICS appears twice in
the project or in two projects, although physically it is just one device.
Parameter
p8839
Description:
Values:
For p8839, the following rules apply:
● The setting of p8839 applies for all drive objects of a Control Unit (device parameter).
● For the setting p8839[0] = 99 and p8839[1] = 99 (automatic assignment, factory setting),
the hardware used is automatically assigned to interfaces IF1 and IF2. Both indices must
be selected so that the automatic assignment is activated. If both indices are not
selected, then an alarm is output and the setting p8839[x] = 99 is treated just like
'inactive'.
