Parallel operation of communication interfaces
General information
The two cyclic interfaces for the setpoints and actual values differ by the parameter ranges
used (BICO technology etc.) and the functions that can be used. The interfaces are
designated as cyclic interface 1 (IF1) and cyclic interface 2 (IF2).
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 optional interface (COMM board) for PROFINET (CBE20) or CANopen (CBE10) for
insertion in the Control Unit.
Parameter p8839 is used to set the parallel use of the Control Unit onboard interfaces and
COMM board. The functionality is assigned to interfaces IF1 and IF2 using indices.
For example, the following applications are possible:
● PROFIBUS DP for drive control and PROFINET for the acquisition of 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 IF2 (CBE20), standard telegrams and PROFIsafe via IF1
● Operation of redundant communication interfaces
