Communication
10.1 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 or CANopen.
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:
