PROFIBUS is tuned for high-speed, time-critical data communication at field level.
Note
PROFIBUS for drive technology is standardized and described in the following document:

Note
Before synchronizing to the isochronous PROFIBUS, all of the drive object pulses must be
inhibited - also for those drives that are not controlled via PROFIBUS.
PROFIBUS interface: The cyclic PZD channel is deactivated when the CBE20 is plugged in!
NOTICE
Destruction of the CU320‑2 or other CAN bus nodes by connecting a CAN cable
Connecting a CAN cable to interface X126 of the CU320-2 can destroy the CU320‑2 or other
CAN bus nodes.
● Do not connect any CAN cable to the X126 interface.

● Master
The following classes are differentiated:
– Master class 1 (DPMC1):
Central automation stations that exchange data with the slaves in cyclic and acyclic
mode. Communication between the masters is also possible.
Examples: SIMATIC S7, SIMOTION
– Master class 2 (DPMC2):
Devices for configuration, commissioning, operator control and monitoring during bus
operation. Devices that only exchange data with the slaves in acyclic mode.
Examples: Programming devices, human machine interfaces
● Slaves
With respect to PROFIBUS, the SINAMICS drive unit is a slave.
