Configuring the PROFIBUS communication with STEP 7

Using a suitable example, the following section provides information on how you connect an
inverter to a higher-level SIMATIC control via PROFIBUS.
What prior knowledge is required?
In this example, it is assumed that readers know now to basically use an S7 control and the
STEP 7 engineering tool and is not part of this description.
A.3.1.1

Creating a STEP 7 project

PROFIBUS communication between the inverter and a SIMATIC control is configured using
the SIMATIC STEP 7 and HW Config software tools.
Procedure
● Create a new STEP 7 project, e.g. "G120_in_S7 ". Add an S7 300 CPU.
● Select the SIMATIC 300 station in your project and open the hardware configuration (HW
● Add an S7 300 mounting rail to your project by dragging and dropping it from the
