Examples: Programming devices, human machine interfaces
● Drive Unit (PROFIBUS: Slave, PROFINET IO: IO Device)
The SINAMICS drive unit is with reference to PROFIdrive, a Drive Unit.
Interface IF1 and IF2
The Control Unit can communicate via two different interfaces (IF1 and IF2).
These interfaces have the following basic characteristics:
● IF1:
PROFIdrive, standard telegrams, cycle synchronization, all DO types, can be used by
PROFINET IO and PROFIBUS
● IF2:
No PROFIdrive, no standard telegrams, no clock synchronization, servo, vector and
infeed, reduced number of transferable data (16 PZDs max.), can be used by CANopen
Note
For further information about the interfaces IF1 and IF2 see chapter "Parallel operation of
communication interfaces for CU320" in this manual.
10.1.2 Application classes
Description
There are different application classes for PROFIdrive, depending on the scope and type of
the application processes. There are a total of 6 application classes in PROFIdrive, of which
4 are discussed here.
