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 in the data transfer
The sequence of drive objects is displayed via a list in p0978[0...15] where it can also be
changed.
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.
10.3.2 Hardware setup
10.3.2.1 Configuring SINAMICS drives with PROFINET
Communication Board Ethernet CBE20
The CBE20 option board is inserted in the option slot of the CU320. The CBE20 is equipped
with four ports that can be used to connect the PROFINET sub-network.
New device ID for PROFINET (from FW2.5 SP1)
From FW 2.5 SP1, a new device ID is maintained in the firmware, which uniquely and
distinctively identifies the drive object (e.g. S120 or G150) where the CBE20 is plugged in.
Note
This new device ID can only be evaluated and processed with SIMATIC S7-CPUs that have
loaded FW version 2.5 or higher. With a different FW version in the S7, no communication
between the S7 and the drive with a new device ID is possible!
