Communication according to PROFIdrive
3.3 Parallel operation of communication interfaces
Parameters for IF2
The following parameters are available in order to tune 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
Meaning of 88xx is identical to 20xx (for IF1)

Note
Using the HW Config configuration tool, a PROFIBUS slave / PROFINET device with two
interfaces cannot be shown. In parallel operation, this is the reason that SINAMICS drive
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'.
● An alarm is issued if the same hardware (Control Unit onboard or COMM BOARD) is
selected in p8839[0] and p8839[1]. The following then applies: The setting of p8839[0] is
valid, and the setting of p8839[1] is treated like 'inactive'.
● If the CAN board (CBC10) is used, the entry of p8839[0] = 2 is not permissible (no
assignment of the CAN board to IF1). An alarm is then issued.
● If p8839[x] is set to 2, and the COMM BOARD is missing or defective, then the
corresponding interface is not supplied from the Control Unit onboard interface. Message
A08550 is output instead.
