Operation
6.13 Parallel operation of communication interfaces
Note
Parallel operation of PROFIBUS and PROFINET
The data of isochronous applications can only be processed via one of the two interfaces IF1
or IF2 (p8815). 2 parameterization 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
Significance of 88xx identical to 20xx

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.
