Example: configuring the frequency converter on PROFIBUS

Task
A drive with a SINAMICS G120 frequency converter is to be controlled from a central
SIMATIC controller via PROFIBUS, whereby the control signals and speed setpoint are to be
transferred from an S7-300 CPU to the drive. In the other direction, the drive is to transfer its
status messages and actual speed value to the central controller via PROFIBUS.
Using a suitable example, the following section provides step-by-step instructions explaining
how to connect a frequency converter to a higher-level SIMATIC controller via PROFIBUS.
To extend the PROFIBUS network to include additional frequency converters, simply repeat
the relevant steps.
What prior knowledge is required?
This section does not explain how to use S7 controllers or the STEP 7 engineering tool.
