Parallel Operation Of Communication Interfaces - Siemens sinamics dcp Operating Instructions Manual

● Alarms or faults are acknowledged using the already known acknowledgment routes.
● Transfer possible via interface IF1 and/or IF2
Note
Constraint
If Shared device is activated, only one of the controllers can receive diagnoses.
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
communication. The diagnostics is issued at the MAP/PAP-submodule.
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
diagnostics.
8.4.4

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
● An additional interface (COMM - BOARD) for PROFINET or EtherNet/IP (CBE20) for
insertion in the Control Unit as an option.
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 actual values / measured values of
the drive
● PROFIBUS DP for control and PROFINET for engineering only
● Mixed mode with two masters (the first for logic and coordination, and the second for
technology)
● SINAMICS Link via IF1 (CBE20); PROFIBUS (only DO Drive, max. 16 PZD) IF2
● Operation of redundant communication interfaces
