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
1)
● Diagnostic parameters:
r8874, r8875, r8876
1)
● Binector-connector converters:
p8880, p8881, p8882, p8883, p8884, r8889
1)
● Connector-binector converters:
r8894, r8895, p8898, p8899
1)
1)
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 PZD Interface hardware assignment
Description: Assigning the hardware for cyclic communication via PZD interface 1 and interface 2.
Values: 0: Inactive
1: Control Unit onboard
2: COMM BOARD
99: Automatic
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]. Then the setting of p8839[0] is valid, and the setting of
p8839[1] is treated as 'inactive'.
● If p8839[x] is set to 2, and the COMM-BOARD is missing/defective, then the
corresponding interface is not automatically supplied from the Control Unit onboard
interface. Message A08550 is output instead.
