Note
Parallel operation of PROFIBUS and PROFINET
Either the isochronous mode or PROFIsafe functionality can be assigned to an interface via
p8815 (IF1 or IF2).
Example:
• p8815[0] = 1: IF1 supports the isochronous mode.
• p8815[1] = 2: IF2 supports PROFIsafe.
Additional configuration options are available if additionally the PROFINET module CBE20 is
inserted in the CU320-2 DP:
• p8839[0] = 1 and p8839[1] = 2: PROFIBUS isochronous, PROFINET cyclic
• p8839[0] = 2 and p8839[1] = 1: PROFINET isochronous, PROFIBUS cyclic
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

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 2 projects, although physically it is just one device.
