Communication PROFIBUS DP/PROFINET IO 10.3 Communications via PROFINET IO

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.

10.3.2Hardware setup

10.3.2.1Configuring 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!
