Parallel Operation Of Communication Interfaces - Siemens SINAMICS S120 Function Manual

Data transfer for cyclic communication, the following applies:
● For PROFINET, there is a unique assignment of the drive objects to the slots of the cyclic
Data transfer for acyclic communication, the following applies:
● There is no slot or subslot configured at which diagnostics can be issued.
● Faults or alarms that occur are routed along the BICO connections to the drive objects.
Display of error classes according to PROFIdrive:
● For transfer with PROFINET, the PROFIdrive error class and the extended channel

Parallel operation of communication interfaces

Cyclic process data (setpoints / actual values) are processed using interfaces IF1 and IF2.
The following interfaces are used:
● Onboard interfaces of the Control Unit for PROFIBUS DP or PROFINET.
● An additional interface (COMM - BOARD) for PROFINET (CBE20) or CANopen (CBC10)
Parameter p8839 is used to set the parallel use of the Control Unit onboard interfaces and
COMM - BOARD in the SINAMICS system. The functionality is assigned to interfaces IF1
and IF2 using indices.
For example, the following applications are possible:
● PROFIBUS DP for control and PROFINET to acquire
● PROFIBUS DP for control and PROFINET for engineering only
● Mixed mode with two masters (the first for logic and coordination and the second for
● SINAMICS Link via IF2 (CBE20); standard telegrams and PROFIsafe via IF1
● Operation of redundant communication interfaces
