Configuration telegram (ChkCfg)
Using the configuration telegram, a slave knows how many setpoints are to be received from
the master and how many actual values are to be sent to the master.
For slave-to-slave communication, a special space ID is required for each tap. The
PROFIBUS configuration tool (e.g. HW Config) generates this ID. The ID is then transferred
with the ChkCfg into the drive devices that operate as subscribers.
9.3.4.4 Commissioning of the PROFIBUS slave-to-slave communication
The commissioning of slave-to-slave communication between two SINAMICS drive devices
using the additional Drive ES package is described below in an example.
