Application example
The system consists of a synchronous master (DP master) and at least one
SIMOTION D4x5-2 synchronous slave (DP slave). The synchronous master contains the
master axis; the synchronous slave contains the following axes:
● The axes in the SINAMICS Integrated of the D4x5-2 synchronous slave must exhibit high
performance with a servo cycle clock of 1 ms and an internal DP cycle of 1 ms. This
requires that the internal fast PROFIBUS DP be decoupled from the slower external
PROFIBUS DP.
● The PROFIBUS DP has, for example, a cycle time of 4 ms due to the quantity framework
on the bus; in all cases, its cycle time exceeds that of the cycle clock of the internal DP
interface.
● The master values are transmitted via the DP bus. Further nodes can also be connected
to the DP bus, e.g. DP drives, distributed I/Os, etc.
