Operation
8.4 Communication according to PROFIdrive
Assignment of communication interfaces to cyclic interfaces
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).
With the factory setting p8839 = 99, the communication interfaces are permanently assigned
one of the cyclic interfaces (IF1, IF2), depending on the communication system, e.g.
PROFIBUS DP, PROFINET.
The assignment to the cyclic interfaces can essentially be freely defined by user
parameterization for the parallel operation of the communication interfaces.
Properties of the cyclic interfaces IF1 and IF2
The following table shows the different features of the two cyclic interfaces:

Plugged hardware interface
No option, only use Control Unit onboard interface
(PROFIBUS or USS)
CUD with CBE20 (optional PROFINET interface)
Parameter p8839[0,1] is used to set the parallel operation of the hardware interfaces and the
assignment to the cyclic interfaces IF1 and IF2 for the Control Unit drive object.
