Data Transmission; Hardware Configuration (Configuring Sinamics Drives With Profinet) - Siemens SINAMICS DCM Operating Instructions Manual

10.3.2.4

Data transmission

Properties
The Communication Board CBE20 supports:
● IRT – isochronous real-time Ethernet
● RT – real-time Ethernet
● Standard Ethernet services (TCP/IP, LLDP, UDP, and DCP)
PROFIdrive telegram for cyclic data transmission and non-cyclic services
Telegrams to send and receive process data are available for each drive object of a drive
unit with cyclic process data exchange. In addition to cyclic data transfer, acyclic services
can also be used for parameterizing and configuring the drive. These acyclic services can be
used by the supervisor or the controller.
The total length of the Ethernet frame increases with the number of drive objects in a drive
unit.
Sequence of drive objects during data transmission
The sequence of drive objects is displayed via a list in p0978[0...15]; it can also be changed
using this parameter.
Note
The sequence of drive objects in HW Config must be the same as that in the drive (p0978).
NOTICE
A ring-type topology is not permissible.
10.3.3

Hardware configuration (configuring SINAMICS drives with PROFINET)

Communication Board Ethernet CBE20
The CBE20 option module is inserted in the option slot of the CUD. The CBE20 is equipped
with a PROFINET interface with 4 ports that can be used to connect the PROFINET
subnetwork.
Note
The ports must not be interconnected in such a way that a ring topology is created.
